we own a 96' gmc sierra the truck has been look after very very well has 300,000+ kilometers and is still running great i had in my school shop awhile back and look over it everything in the steering is good same with exaust and motor shape still silent, we replaced the tranny about a two years ago but hey they wear out, anyhow once the truck is warmed up the check engine light comes on and after that the tranny starts to clunk (hard shift) slowing down and speeding up, i had a hand held computer pluged into the truck, a good one at that, and it could tell the light had been on but could not figure out the problem or what was wrong. another thing this does not always happen but we would like to get rid of it so if you have any idea what the problem is please tell.
sorry lol its an automatic
 
your car is OBD 2 which means it can monitor your transmission as well as the engine.it would help if you told us what code is it it but if you take it to your local auto parts store, they can read the code for free and you will prob. find that it is one of you shift solenoids in the transmission.
