transmission replace issue Sign In

1985 GMC S15, 4WD, 2.8L Jasper Engine 173.

I have a 4 speed borg warner T5? in this truck now and when I try to shift from 1st to second it won't go. The shifter lever moves back and forth like the tranny is pushing it away from 2nd gear. I can go 1st to 3rd, then 4th ok, and I can shift into 2nd and start the truck in it will cooperate and move in second, then third, etc.

It does not seem like the clutch is slipping and I don't hear gears grinding. I was told to add tranny fluid and if that didn't fix it the syncronizer was bad?? Did that, same problem.

Can I put a 5 speed S10 manual transmission in in place of the 4 speed w/o modifications (bolt pattern the same)?? Can I keep the same transfer case currently in there? ('83-'89 from the tranny interchange book).

Is there any other way to tell what is actually wrong without dropping the transmission or am I just SOL??

Last, could the clutch be the problem??? All have proper fluid levels.

Please answer all the questions as I am new at this. If Jerry Lewis had a Labor Day Telethon for Mechanical Dystrophy, I would be the Poster Child, lol.

Thanks much, Joe

Will it go into second if you double clutch?

Google or Youtube it. A video would better describe it better than I could.
