I have a 1989 chevy s10 (4.3L) with a 700r4 transmission [all stock] and i
was going down the interstate at about 75mph and approached an incline..
held steady on the throttle and the transmission (even with a recent
filter/fluid change; perfect fluid level) shifted down 1 gear too many or
something but just for a spliit second... then went into the proper gear..
acted fine for the rest of the highway....
then i get to the end of the offramp... come to a dead stop and when the
light turns green I give it gas and it bangs (like bang bang bang) into 1st
then when it shifts into second it shifts HARD... So hard it shutters and
shakes the truck...????
seems fine in the gears after that....
Problem has been ever since...
A close look reveals:
1.) It has no problem with reverse
2.) It will grab 1st fine when manually put into 1st (or 2nd) AND...
3.) Has no problem with the 1-2 shift when manually put into 2nd (What I put
it in to start off with now)
4.) Only has the problem in drive and overdrive
5.) Can still do a mean brake stand!
Any help would be appreciated. I'm mostly wondering if there is a quick fix
(Like something to replace with the tranny in the vehicle) or If I really
have to switch it out with my space 700r4 from the same type of truck
Thank You! ---> jurtaman!
