Unfortunately if it is brown rusty color you have a serious problem! this usually occurs once you have burned up the clutch plates with in the core of transmission! honestly I do not aim to discourage you but your probably going to have to eventually change this transmission! if you have a strong aroma from the dip stick it is burned up!!!! I have change plenty of these over the years due to the same circumstances.Good luck and hope that it all works out for you,John

I have a 1990 GMC Suburban. The transmission is slipping. I still have reverse, 1st, and can manually shift into second. No 3rd or overdrive... it just slips. What should I look for?


is it a 4l80e electronic shift transmission....it may be an issue with the solenoid pack...you can take it to someone who has a scanner tool for the trans...if it is indeed a 4l80e

it may be a bad transmission modulator valve located on the side of your transmission,vacum operated. a sudden downshift or forward shift when unexpected is sign of a bad modulator valve or a vacum leak to the transmission.best to shop around for a garage w/references when it comes to transmission work though. check all the vacum lines to your transmision,you need to look on the underneath side of your truck on the side of transmission for a loose or disconnected vacum line on the side of the transmission. when you feel the vacum line,follow it to the top of engine,the vacum line is about 3/8th line,and may be disconnected or losing air. to make this short,when you drive the car,start out in low gear and shift the transmission,manually from 1st to 2nd to 3rd does it do right with no slipping? if it does this right and shifts great manually,the modulator valve on the side of the transmissions bad,or a bad vacum leak in-between.thank you for choosing fixya.com

Shift letters for a 1992 chevy 2500. what does each mean?


The D inside of an O is for overdrive. It is an automatic overdrive transmission. There isn't an overdrive button on it. If you want to disable the overdrive you have to shift down a gear.
