i was driving my car kinda hard today an noticed when i floor it on the hwy at like 80 it seem so kick down kinda hard and it doesnt seem to do that from a 30 punch. is this normal or somthing i should get checked out?

 

get it checked... tranny may be going

 

Check to see if your fluid is burned/brownish.

Also, how hot was it in your area? Tranny can shift more harshly when hot.

 

it was about 85 and i was driving alot... is there a trans cooler you can recommend or that will fit in front of the radiator well. also would a trans cooler void my warranty?

 

are you saying that it is just shifting hard when shifting up or did it down shift on its own?

 

only when i floor it and it downshifts
