1990 chevy 1500 4.3 vortec v6 automatic. it had been shifting hard and after it was drove for about 30 minutes, it was like something was getting hot and it quit pulling after it set for about 30 minutes, it would take off and start pulling again. we took the transmission pan off and in the bottom of the pan was some kind of gasket or some kind of band.i thought it was the gasket from the pan but it was it good shape. does these models got a thing called transmission brake band and could that be why we are having trouble out of the transmission and if so were can i find one of these? please help!!! thank you

 

no sugestion on this. needing help. thats your job to answer questions

 

First off, I don't know of anyone that gets paid to post possible answers, second, perhaps no one knows? My guess is if it is a band (yes 1, 2nd, 3rd, ect) are "bands". I don't know how one could survive if it "came off". Sounds like what I'd say is it is new tranny time.

 

It's a "job"? Don't forget then when Christmas bonus time rolls around!
Could be that "gasket" material you found was part of a clutch lining. The trans has a clutch pack (disc/plate/disc/plate, etc) which is what makes it go. Terribly worn or disintegrating discs is what makes it not go.
