How to Put Transmission Fluid in an Cars

by Contributing Writer; Updated June 12, 2017

Both automatic and manual transmissions equipped in the Volkswagen car are sealed units. While there is a drain plug and a fill hole for the transmission, there is no dipstick within the engine bay to either check the transmission fluid levels or fill the transmission with fluid. The fluid within the transmission is meant to last for the life of the vehicle, but premature wear can make replacement necessary. It is advised that you take your Volkswagen car to a trained Volkswagen car mechanic for transmission-related servicing. However, you can drain and fill both manual and automatic transmissions by following the steps below.

 How to Put Transmission Fluid in an Isuzu Rodeo

Park the truck on a level surface and set the emergency brake. Leave the engine running. The transmission fluid levels in Isuzu Rodeos has to be checked with the truck running regardless of what kind of transmission they have.

Crawl under the passenger side of the Rodeo and locate the drain plug. If the transmission is a manual transmission, the fill plug will be on the very back of the transmission. There will be two plugs on the bottom of the transmission. The drain plug is in the middle of the transmission on the bottom. The fill plug is about 6 inches to the rear of the drain plug; it will be inside a recessed groove on the rear of the oil pan.

Remove the fill plug on the rear passenger side of the transmission with the ratchet and 7/8-inch socket. Turn the fill bolt counterclockwise to loosen and remove the plug. If no transmission fluid comes out of the recessed fill hole, then the transmission fluid level is low.

Add the transmission fluid by sticking a long plastic tube inside the recessed hole and using a transmission fluid pump on the other end of the plastic hose. Fill the transmission with the engine running until fluid runs out the recessed fill hole. Remove the plastic hose. Reinsert and tighten the fill plug. If the Isuzu Rodeo has an automatic transmission, you will check the transmission fluid level with the dipstick. If adding fluid is necessary, you'll add fluid through the filler neck where the dipstick seats.

Locate the transmission dipstick on the passenger side of the engine bay. The transmission dipstick should have a red pull handle on it. Remove the dipstick, wipe it clean, insert it fully into the filler neck, pull it out again and check the fluid level on the dipstick. There is a "Full" mark on the dipstick and an "Add" mark below the full mark.

Put the longneck funnel into the dipstick filler hole and add Mercon-3 automatic transmission fluid a half-quart at a time until the transmission fluid level reaches the full mark. The engine has to be running to get an accurate fluid reading on the transmission dipstick.

Items you will need

  • Ratchet

  • 7/8-inch socket

  • Transmission fluid pump

  • Long plastic tube

  • Long neck funnel

  • Dexron-3 automatic transmission fluid

 How to Add Transmission Fluid to a Mountaineer

Locate the transmission of the Mountaineer. The drain plug is located on either the left or right side of the transmission.

Remove the plug by unscrewing it with your hand. Place a pan underneath the transmission so that any excess fluid that may leak out can be caught.

Place a fluid level tube into the hole and attach a small funnel to the end of the tube.

Pour the transmission fluid into the funnel until the compartment is full. A completely dry Mountaineer will generally take around five quarts of fluid.

Replace the plug and start the engine. Let the engine idle for about five minutes to allow the fluid to fully lubricate the transmission.

Items you will need

  • Pan

  • Fluid level tube

  • Small funnel

  • Transmission fluid

 How to Put Transmission Fluid in an E320 Mercedes Benz

Turn you car on, allowing it to run for about 10 or 15 minutes to let the engine warm up.

Pop the hood of the car and locate the transmission cap. You will see a red cap behind the engine and near the transmission.

Unscrew the transmission cap. Insert the dipstick into the fluid well. Let it set for about 10 or 15 seconds.

Pull the dipstick out and check the readings. You will notice a line on bottom that says "LOW" and one on top that says "FULL". If fluid does not reach the "LOW" line, you will need to add more.

Pour transmission fluid directly into the hole where you unscrewed the cap. To re-check levels, wipe the dipstick clean with a rag and repeat the process. Once the fluid level is correct you may screw the cap back on and turn off your vehicle.

 How to Add Transmission Fluid to a 2001 Isuzu Trooper

Park the 2001 Isuzu Trooper on a level surface and engage the parking brake.

Slide under the 2001 Isuzu Trooper near the driver-side door. Locate the transmission pan on the bottom of the transmission. There are two plugs on the bottom of the transmission. The plug in the center of the pan is the drain plug. The plug in the recessed area near the back of the pan is the fill plug. You have to add transmission fluid to the recessed fill hole with the engine running.

Crank the 2001 Isuzu Trooper and let it run for about two minutes to heat up the transmission fluid. Crawl back under the Trooper and position the drip pan under the fill plug on the back of the transmission pan.

Loosen the fill plug with the 1/2-inch drive ratchet, extension and socket by turning the fill plug counterclockwise. Then pull the plug out and set it on the floor.

Pour transmission fluid into the handheld fluid pump. Slide the long plastic tube onto the end of the pump. Then insert the other end of the plastic tube into the recessed fill hole. Pump transmission fluid through the fill hole until the fluid starts to run out of the hole.

Pull the plastic tube out of the fill hole and screw the fill plug back in the hole. Tighten the fill plug back down tight with the ratchet, extension and socket. Pull the drip pan out from under the Trooper and turn the engine off.

Items you will need

  • Drip pan

  • 1/2-inch drive ratchet

  • 1/2-inch drive extension

 How to Add Transmission Fluid in a Duramax

Drive the Duramax around for about 20 minutes to heat up the transmission fluid. The hot transmission fluid will give you a more accurate reading on the dipstick. Park the Duramax on level ground and open the hood.

Locate the automatic transmission fluid dipstick on the rear of the engine. Pull the dipstick out and look at where the fluid level is. Wipe away the excess fluid from the dipstick with a shop rag.

Slide the long neck funnel into the dipstick holding tube. Pour Dextron VI automatic transmission fluid into the funnel until the fluid level is near or at the full mark on the dipstick. A completely empty transmission on a Duramax diesel engine will hold around 13 quarts of fluid. A regular drain and fill will take 7.4 quarts of fluid to fill the transmission with fluid.

Pull the funnel back out of the dipstick tube and reinsert the dipstick. Close the hood.

Items you will need

  • Long neck funnel

  • Shop rag

  • Dextron VI automatic transmission fluid

Checking and Adding Transmission Fluid

Make sure your car is on level ground. Put the car in park and turn on the engine. Let the engine idle for a couple of minutes.

Open the hood. Locate the transmission dipstick, which is found on the passenger's side near the back. Pull out the dipstick and wipe it off with the rag. Insert the dipstick again and pull it out. Check the level. There are two gauges, one each for hot and cold engines. If you just started the vehicle you will want to make sure the fluid is in line with the cold mark, and if the car has been running for awhile, the hot mark.

If the fluid is low, it is time to add some more to bring it up to the proper level. Remove the dipstick and put it off to the side. Add a small amount of ATF PLUS 3 Type 7176 fluid into the dipstick tube. Let it settle for about five minutes and then check again. Do this until the desired level is reached.

When checking the level also check for the color and transparency of the fluid. It should have a reddish color and be clear. If the fluid is dark brown or black and hard to see through then it is time for a change.

Items you will need

  • Clean rag

  • ATF PLUS 3 Type 7176 transmission fluid

 How to Put Transmission Fluid in a Jeep Cherokee

Engage the parking brake on your vehicle. Also make sure the car is in "Park." Make sure your car is parked on level ground before proceeding, ensuring stability of your vehicle and an accurate fluid-level reading.

Start the Jeep and let it idle for about 15 minutes. Transmission fluid must be checked while your engine is at operating temperature in order for the fluid level to be accurate. Letting your car sit gives the engine time to heat up.

Pop the hood and locate the dipstick near your car's transmission. This will be located at the rear of the engine. The dipstick will contain a colored circle at the top, usually yellow or red.

Remove the dipstick and wipe off any transmission fluid. You must clean off this fluid so that, when you reinsert the dipstick, any fluid left on the stick will accurately reflect the level in your transmission. Any fluid on your dipstick at this point is just excess and does not reflect a proper fluid-level readout.

Replace the dipstick. Wait 3 seconds to allow fluid to fall in place, pull the dipstick and measure the fluid levels.

Check to make sure that your transmission fluid reaches the "HOT" arrow. If it doesn't, add more transmission fluid.

Place a funnel over the tube where the dipstick is housed and slowly pour transmission fluid, allowing it to flow into the fluid well. Repeat the process by adding more fluid and checking the dipstick until it reaches the "HOT" arrow.

Items you will need

  • Automatic Transmission Fluid 4 (ATF 4)

  • Paper towels

 How to Add Transmission Fluid to a Dodge Stratus

Park your Stratus with the engine idling. Engage the parking brake. Cycle the gear shift through each gear and place it in neutral. Raise the hood of the Stratus and lift the prop rod to support it.

Pull the transmission fluid dipstick to test the fluid level. The dipstick is located in the front center of the engine compartment. Pull the dipstick out of the tube and wipe it clean with a dry rag. Insert the dipstick and promptly remove it. Read the fluid level on the stick. The fluid should be at or near the “hot” level.

Place the transmission in park. Turn off the ignition. Raise the car with a jack. Place the Stratus on a set of jack stands. Locate the drain plug near the bottom of the transmission. Unscrew the drain plug and quickly insert the transmission fluid bottle. Squeeze the bottle to add fluid to the transmission. Check the fluid level again to confirm.

Raise the car with a jack to remove the jack stands. Lower the car to the ground. Close the hood.

 How to Add Transmission Fluid to a 1997 Volkswagen Jetta

Drive the Jetta for at least 10 minutes. This will warm up the transmission fluid. Drive the Jetta into your work area and apply the brake. Move the shifter through each gear, leaving it in gear for 3 to 4 seconds before moving to the next gear. Return the shifter to park (or neutral if it is a manual).

Leave the engine running and use a drive-on or four-post lift to raise the vehicle. The vehicle must remain level when reading the fluid level and replacing the fluid.

Locate the service plug on the lower right-hand passenger side of the transmission. Place a catch pan underneath the transmission and remove the plug with a ratchet and socket. If the fluid level is normal, a small amount of fluid will leak out.

Locate the fill plug on the side of the transmission fluid pan. Loosen the plug with a ratchet and socket and use the VAG 1924 transmission filler tool or equivalent to pump the VW transmission fluid into the pan. Pump the fluid into the pan until it overflows out of the plug. Reinsert the plug into the side of the pan.

 How to Add Transmission Fluid to a Mazda B4000

Start the engine on the truck. Allow it to idle for about five minutes so the engine can heat.

Release the hood trigger and open the hood. Make sure it's propped up.

Pull out the transmission dipstick located near the engine. Wipe it off with a towel and reinsert it.

Pull the dipstick out again. Check the bottom of the stick for the fluid level. There are two dots on the stick, one above the other. Your truck has the proper amount of fluid if the fluid level lies between those two dots. If it lies beneath the bottom dot, add fluid.

Pour transmission fluid into the transmission reservoir. Measure the fluid level periodically, and continue to add fluid until the correct level is attained.

 How to Add Transmission Fluid to a 2007 Toyota Tundra

Drive your Toyota Tundra around for 15 to 20 minutes. This gets the engine going and heats up the transmission fluid, which must be hot before it can be changed. When finished, park on even ground but leave the engine running.

Lift the truck using jacks or ramps and locate the transmission under the front of the truck cab. Remove grease from the drain plug with a clean rag and cleaning solvent. Also, wipe off any dirt or grease in the area around the plug.

Remove the dipstick from the filler tube. Place the funnel into the filler tube and put the drain pan beneath the tube to collect the old fluid.

Use the socket wrench to remove the overflow plug and the refill plugs. The old fluid will drain out into the pan. Be sure not to let the fluid touch you because it should still be very hot and could burn.

Wait for the old transmission fluid to stop draining. Pour the new transmission fluid through the funnel into the filler tube. Wipe off the dipstick using the rag and use stick to monitor the level of fluid inside the tube. Stop adding fluid when the level indicated by the dipstick reaches the desired point. Otherwise, continue adding the transmission fluid until it starts to trickle from the overflow tube. Note that a slow steady drip is not a trickle and, as such, does not mean that the fluid is at the desired level.

Install new overflow plug along with a new gasket, and then turn off the engine. Install a new refill plug with its own new gasket in place of the old one. Replace the dipstick in the filler tube and start the truck without revving the engine. Let it run for 5 to 10 minutes, then shift the gears a couple of times, finally putting the truck back into park.

To ensure everything is in order, examine the dipstick again and see what fluid level it indicates. Add more transmission fluid using steps 4, 5, and 6, if necessary (though the new overflow plug and refill plug need not be replaced again).

Items you will need

  • Jacks or Ramps

  • Transmission fluid

  • Cleaning solvent

  • Torque wrench

  • Socket wrench

  • Drain pan

  • Clean rag

  • New overflow plug with new gasket

  • New refill plug with new gasket

 How do I Add Transmission Fluid to a Jaguar XJ8?

Start the car. Let it sit for about 2 minutes.

Pop the hood of the car. Pull the dipstick from the transmission. The dipstick is located at the front of the engine underneath a few hoses and cables; use a flashlight to find it if necessary. Wipe it clean with an old rag or a set of paper towels, and then re-insert the dipstick. Pull it once more so that you can measure the transmission fluid levels.

Check the transmission fluid level using the lines at the end of the dipstick. To add more, place the funnel into the transmission fluid cylinder, which is the same hole you pulled the dipstick from, and pour in the fluid.

Re-measure your fluid levels. Repeat this process until an adequate level is reached.

Items you will need

  • Long funnel

  • Transmission Fluid

  • Flashlight (optional)
