How to Troubleshoot a Chevy Silverado Transmissionby Lawrence Stephens
Troubleshooting the transmission in your Chevy Silverado may seem like a daunting task to someone who has never done it before, but there a several common things you can check for before you need to take the vehicle to a mechanic. By troubleshooting the transmission yourself, you may find that the problem can be fixed by yourself and could save you a lot of money in mechanics fees. If you are unable to diagnose the problem, you will need to have it looked at by a certified automotive repair technician.
Crank the engine and allow it to run until the temperature gauge needle is resting in the center of the gauge.
Open the hood of the vehicle and remove the transmission dipstick. The dipstick is located at the rear of the engine.
Clean the transmission fluid from the dipstick and re-insert it into the filler neck. Push it all the way back down.
Remove the dipstick again and check the transmission fluid level. The level should be between the two marks on the end of the dipstick. Put more fluid into the vehicle, if needed.
Enter the vehicle and put the transmission in gear. If there is a clunking sound as you do this, the transmission mounts may have failed.
Drive the Silverado for a short time. If the transmission slips out of gear while driving, the clutch or torque converter may have failed and it will need to be taken to a qualified automotive mechanic.
