How to Remove the Transmission From Carsby Contributing Writer
Transmissions are a work of automotive genius. The transmission takes power from the engine and then multiplies this power through a series of gears to make the car go. When you have a four wheel drive vehicle, like a Jeep car the transmission works with a transfer case that splits the power in half to work both the front and rear axles. You need to have some experience with cars in order to be able to remove the transmission from a Jeep car. This is a project that will take some time to do, so allow yourself at least two days in order to fully complete it.

Chock the Jeep's tires and set the parking brake. Remember, putting the vehicle in “Park” only works when there is a transmission in it. With nothing holding the wheels in place, it will be necessary to have the vehicle safely chocked. Bricks, pieces of wood and actual wheel chocks all work well.
Remove the drive shaft. Technically, only one end of the drive shaft needs to be removed, but it is recommended to remove it completely to avoid any problems when the transmission comes out. If your model has a slip-yoke (the drive shaft slides into the transmission as opposed to being locked in), be aware that some or all of the fluid will likely come out with the drive shaft, so having a drain pan handy is a great idea.
Undo the transmission bolts and the shifting linkage. The shifting linkage can be found on the driver's side of the transmission, near the top. Simply unhook it and move it out of the way for removal. Put a transmission jack under the transmission to stabilize it and have your partner steady it with their hands. Then loosen all the bolts around the transmission and be sure you remember the two hard-to-reach ones at the top. Keep the bolts in a pan or other container so they do not get lost.
Remove the transmission. Pulling slightly back on the transmission will disengage it from the engine. Make sure that you and your partner have the transmission balanced well on the jack at this point because, if it starts to fall, it will be very hard to stop. Slowly lower the jack until the transmission can be slid out from under the Cherokee.
Items you will need
Jack up the Jeep and secure it on four jack stands so you have room to get beneath the SUV. Remove the exhaust and the skid plate from the underneath it with the socket wrench set.
Use an open-ended wrench to disengage the rear driveline from the transmission. Repeat this process with the front driveline. Detach all wiring from the transmission. Remove the transfer case and linkage from the back of the transmission using the socket wrench by unbolting it and pulling it off the transmission.
Position the transmission jack beneath the transmission and jack it up until it touches the bottom of the transmission pan. Loop the chains on the jack around the transmission. Bolt the opposite end of the chain to the jack with the open-end wrench. Confirm that the transmission is secure.
Use the socket wrench to remove the transmission crossmember and rear transmission mount from the frame. Pull the crossmember away from the frame so that you can remove the transmission from beneath the vehicle without obstruction.
Use the socket and ratchet to unbolt the transmission from the engine. Unfasten the clutch brace rod before lowering the transmission away from the motor with the jack.

Removing the Starter and Transmission Fill Tube
Pull your car into the garage and lift the hood. Disconnect the negative battery cable (black cable). You can do this by loosening the nut that holds the clamp tight, and pulling the cable free from the battery.
Lift the vehicle with the floor jack and support the jeep with jack stands. When the car is completely secured you can remove the jack.
Remove the screws that are holding the upper transmission fill tube bracket. You can then take off the fill tube.
Remove the torque housing converter cover. The cover is held on by bolts so you need to find the right ratchet and socket to fit the bolts. Remove the bolts and lift off the cover.
Label all the wires that are connected to the starter. Use a small piece of duct tape and the permanent marker. Once the wires are labeled remove them from the starter. Remove the bolts that hold the starter to the engine block. Take the starter out of the jeep.
Remove the Driveshaft
Take you white chalk and mark the position of the driveshaft at the transfer case and front and rear axle pinion yokes. The reason that you have to mark the driveshaft is that it has to be reinstalled the same way so that there are no vibrations when you're driving.
Disconnect the U-bolts that are holding the U-joints to the front and rear axle pinion yokes.
Slide the rear driveshaft underneath the rear axle to remove it from the transfer case. Then remove it from the vehicle.
Remove the front driveshaft by sliding it forward underneath the front axle to remove it from the transfer case, and then remove it from the jeep.
Removing the Throttle and the Shifter Connections
Remove all the screws and nuts that secure the center console to the body hub. Once the the bolts and screws are removed you can remove the center console from the vehicle.
Remove the the cables that connect the shifter to the transmission. When you have removed the shifter cables you can remove the shifter assembly.
Put a waste pan underneath the transmission and remove the plug so you can drain the transmission fluid. Keep the pan underneath the drain plug until you're sure that it's completely drained.
Find the correct size ratchet and socket and remove the bolt that connects the throttle rod to the carburetor. Turn the throttle rod until it comes loose from the throttle valve lever. When the throttle rod is loose you can remove the throttle rod from the vehicle.
Take off the spring that is attached to the throttle valve lever.
Take the electrical connector off of the neutral safety switch. Then unscrew the electrical connector from the transmission.
The Final Steps of Removing the Transmission
Take your chalk and mark the position of the torque converter and engine flexplate. The reason for marking this is because you have to put the torque converter back in the exact same position.
Remove the flexplate and the torque converter bolts. Remove theses bolts and then you can take off the flexplate.
Put a transmission jack under the transmission and make sure that the jack is secure. Secure the transmission on to the transmission jack with a length of chain and bolt it to the jack.
Get the proper ratchet and socket and remove the bolts that attach the transmission crossmember to the transmission. Remove the crossmember.
Disconnect the transmission cooler lines from the transmission. You need to plug the ends of the lines with old rags to keep from getting dirt or water in the lines.
Get a ratchet and socket that fits on the bolts that connect the transmission to the engine. Remove these bolts.
Remove the transmission and transfer case as one whole piece. Slide the transmission straight back until it comes out of the flexplate and crankshaft. Now you can lower the the transmission jack and remove the transmission from underneath the car.
