I used to manually shift my 1997 Trans Am when i would race i was wondering was this bad for my automatic transmisson bc recenty i had problems with my transmission i used to to have hard shifts when i would gun it it would have a second gear chirp its doesnt happen any more now it feels like it wants to shift hard but instead it feel like it starts to slip to second then again to third gear but i take well care of my trans getting it oil change and also tranmissiion oil change and flushed every 10000 mile i have about 102000 miles on it im the second owner of this bird Ihad it when it had 72000 miles on it it was in perfect shape when i got it just feel like its lost its power due to the transmission problems. Ur thoughts on my perblems plz?

 

Just a lot of miles on the trans. The bands and clutches will wear out with time even if you change the fluid out often.

 

also do not manually shift an auto tranny, just put it in overdrive, and let it do the rest. I just got a brand new tranny, clutches, and stall converter put into my car cause i f-ed up my last one. I knew the guy so he didn't charge me labor but it did cost me $3,200 for a new tranny and a stall and clutch upgrade.

 

Does it shift when as soon as you shift it? If not, you might want to get a valve body recalibration (shift kit)kit to make it an automatic/manual valve body so it puts less stress on the transmission.

 

There is no need to manually shift a computer controlled transmission such as the one in your car. The computer knows when an how to shift better than you do. Never the less, your transmission is ready for major repairs, and a shift kit may help temporarily, but it will start slipping again fairly soon.
