Thread: Shifting hard/jerking when shifting

Hey guys, I just recently bought a 99 gtp. Anytime I drive the car normal, it shifts ok, still kinda hard. When I give it a lot of gas, it shifts really hard almost as it's jerking the whole car. The guy I bought it off of, just had the torque converter and flywheel replaced and fluid exchanged. Any ideas? Maybe a tranny or motor mount?

I asked the guy that I bought it from, and he sent me a link of a shift kit he put jn. It's a thrasher one

He said that it's the shift kit that I'm feeling. He said it's supposed to **** harder than normal..

That's pretty much what it is.

I'm not sure about the thrasher shift kit, but other kits have firmness levels. the transmission I have, and the shift settings in my computer will chirp the tires on a 1-2 shift when the pedal is pushed down all the way, which you can probably imagine is a hard shift.

I am in the car now, no codes whatsoever

Maybe it's normal. I'm thinking it's the thrasher shift kit.

your power level should be there, maybe if you had some transmission work done, or a more aggressive trans tune. my shift time is .0125 in pe mode
