| Option 1: |
Four options of shifting firmness
Easy to follow instructions
No special tools required
Comes with shims and filter
Our transmission shift kit improves the shifting of any 4T65e. It works on the standard 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 keep the clutches from slipping and burning. We do not recommend this kit for cars running 20" wheels.
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.
Perfect time to upgrade to Dexron 6 fluid !
Works on 4t65e '98+ GT/LS, '97+ GTP/GS/SSEi.
Also works on Pontiac Montana!

I have installed two of these kits on both of my cars...the kit definitely makes a difference, especially when the transmissions downshift to accelerate...would buy another kit if i had any other 4t65e trans
fixes the hard shift from the p1811
2006 grand prix.been having the hard shifting on and off for a year or so,heard about this kit solving it,and it has.used the same combination judd did becuase i didn't want too hard of a shift.easy to do,and it works
Love it. I think 3/4 on both side of both accumulators would be a nicer shift in 1-2. 2-3 is a very nice shift. It's not neck breaking at all, I think it's just right. Definitely recommend. :)
I put this kit in about a month and a half ago, car has 160k miles. Shifts much better, took about an hour and a half taking my time. Used the recommended settings. No regrets so far.
grest kit for the price would recomend..
