This product is currently out of stock.

Our transmission shift kit speeds up the shifting of any 4T65E. It works on the standard non HD and HD versions of the transmission and can be installed in 2 hours. Shift kits can increase the chance of hard part failure but they do increase clutch life. We do not recommend this kit for cars running 20" wheels due to the chance of breaking an input shaft due to additional rotational weight.

We found with many kits is the lack of instructions as it relates to shift firmness. Many users find themselves guessing at how firm to set up their kits or end up with a kit that shifts great on the 1-2 and weak on the 3-4. Because our kit comes with more shim sizes than our competitor's kit, you can choose 4 levels of shift firmness for the 1-2 and then again for the 2-3 shift. Only ZZP brings you a kit with the options and instructions to get the precise shift quality you desire and all at a price you can afford.

What is included in the kit are a bunch of various sized shims, a new transmission filter, and detailed instructions. You can generally reuse your trans pan gasket since it is rubber.

Perfect time to upgrade to Dexron 6 fluid.

Works on 4T65e '98+ GT/LS, '97+ GTP/GS/SSEi. Also works on Pontiac Montana.

good product

Very easy install. I wish I would have put in the 1 inch and 3/4 inch spacers in the 3-4 shift and 3/4 inch 3/4 inch spacers in the 1-2 shift. but the change is definitely an improvement over stock.

Didn't install

I love zzp's parts. I ordered a PCM tune and shift kit,trans pan dexv1. guys to be honest I was so happy with how much harder the car shifted with ZZP'S tune that I really didn't want to mess WTH a shift kit. Now maybe you guys that don't have a trans tune this wld be great but I don't want to over do it and start hurting the trans. My opinion get the 1.0 tune first then if you want a harder shift then install the kit. I did swap to new fluid,filter,al trans pan. Just my opinion tho
