4T65E Shift Kit

SKU: ZZ-4T65E-SK

$18.99 Sale price

Regular price $18.99

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.

Cheap and respectable

This kit gave me exactly what I was looking for. No more sloppy or hard *****, and no more trouble downshifting. ZZP makes it easy with the setup they suggest and the instructions they send. Thanks again ZZP.

Great kit, solved my trans problems.

So far, after having this kit on for about a week now, I can say that it has taken away my sluggish 1-2 shift that I have in the morning and made everything transmission wise smoother, but harder shifts, which is good. 2-3 shifts are a lot quicker now and the overall shift points are a lot easier to identify and predict, no longer having erratic shift points.
