Default Shift Kit.

Im bidding on a intense shift kit for the car, and Im wondering If i can put this on in the driveway on a set of jackstands. Granted I will be putting new tranny fluid in, but the principal question is how easy is it to install. Oh yea, if there are any GR or local area members that are thinking of a shift kit, and would want to come over and assit or see what is needed, your more than welcome, just PM. [assuming I win the item ]

I had one in my 98 GTP. With the option of reprog PCMs nowadays, I dont see the need for the shift kt. HONESTLY.

But if your not doing a PCM, and just want some firmer shifts. Then i guess a shift kit is the best option.

As long as you drain the fluid first, the install is pretty much straight foward. There are 7 8mm bolts that hold the accumulator housing to the tranny. And 4 that bolt the housing together. Just make sure you have the lines in and tight when your puting it back together. There are only 3 lines to worry about, they are all metal and only go in one way. You will be fine.

i would think that shift kit would make a greater improvement to shift firmness than simply boosting the overall line pressure with the PCM..

Agreed. Having had the PCM first, I can tell you it doesn't do JACK compared to a good shift kit.

Keep in mind I don't have the run of the mill DIY shiftkit. My valvebody was extensively modified during install of the kit.

The shift kit works mechanical magic in a way that a PCM can't hope to do.

But you can't adjust line pressure with a 4t60 via PCM. You can with the 4t65 though.

But we do have the option for an adjustable vacuum shift modulator that does the same thing.

A shift kit is alot more than raised line pressure. That'* just a tiny piece of it. Firmer shifts is one thing, QUICKER upshifts and downshifts is a totally different ballgame for performance and longevity of the trans.

If the line pressure was the only issue, the only aftermarket for the 4T60 would be the vacuum modulator. But it'* not. The 4T60 shift kit is extensive, and the 65 is almost identical in nearly every way.

Raised line pressure doesn't come close to replacing a good shift kit.

For shifts, PCM<Shift kit by a huge margin.
