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.

It works great, I put it in in hopes of solving some hard shifts and it worked great.

Works on Volvo!

My 01 s80 2.9 has a 4t65 transmission that shifts great. I wanted to service and figured why not upgrade? Went on the stiffer setting with the spacers and it shifts like a brand new transmission! ZZP for the win!

Easy install

I installed this in a 2008 Grand Prix GXP. Super easy, just follow the supplied directions. Maybe add some detail on the thermostatic element in case it falls out like mine did, I figured it out no biggie. I didn't have any issues with my transmission, just wanted to change the filter since it was probably the first time since I bought the car with just 52k miles. I noticed a 10+ degree reduction in temps. Also like the way it shifts, nothing too drastic, just firm like they should for those of us that like performance.
