Is it bad? I usually just shift it manualy here in town, but just while cruising. The transmission is in a '96 Trans Am with 96K on it and I was wondering if it would mess anything up. I wouldn't want to have to buy another transmission now.

 

shouldnt matter

 

yea i usually do that too but when i got my transmission rebuilt for my 73 camaro the guy said its fine up shifting manually but its not a good idea to downshift manually like you would do in a manual, let the car stop then shift back to one and then keep going

 

Alright well thats good, Thats what I do. I usually just wait till I hit a dead stop to shift down to first. Thanks for the help guys.

 

Your trans is controlled by your pcm, you can select any gear but the pcm is still going to shift when it decides to.

 

Why bother doing that? You're not going to make the car any faster by manually shifting an electric automatic. If you want to manually shift an automatic, put a manual valve body in it

 

but downshifting to bring the revs up is so much fun.

 

its pointless....theres no way you can shift faster than the computer. there is no point to manual shifting unless you have a turbo 300 or 400 tranny....

 

I have a TH400 with a ratchet shifter, it lags a second when i upshift if i dont let off the gas, this good or bad? I almost think i have a better time when i leave it in Drive

 

my car shifts into second whenever i put it in second from first. i can be rolling 5mph in first, put it in second and if shifts into it right when i do it, not when it feels like it. it will also take off in second too if i leave it in second from a stop. but ive heard manually shifting them is bad so i dont really do it anymore.

 

It comes handy in stuff like autocrossing. As for straight line just let the D take care of that..

 

Is there not some table on Hptuners for manual shift?? i have seen it butnever dared to change anything??? and yes for autoX its nice to have have
