jake91 Posted February 18, 2010 Report Posted February 18, 2010 what would be a good one for my car, dont want something that is jaring when it shifts normal but at wot i want somthing that will be quick enought to almost or lightly squeak the tires in second Quote
digitaloutsider Posted February 19, 2010 Report Posted February 19, 2010 Those two things do not go together. Additionally there are some pretty good writeups on shift kits on the forum. Personally, its not worth your time. Quote
RobertISaar Posted February 19, 2010 Report Posted February 19, 2010 Personally, its not worth your time. X2... for a stock motor anyway. start making more power and then it would be a good thing to help your clutches last longer. Quote
WhatTheFehl Posted February 19, 2010 Report Posted February 19, 2010 I've never understood why anyone would essentially ruin a perfectly good automatic transmission by putting a shift kit in it. If you want more noticable shifts, put a manual tranny in. The S-10 we had at work had a shift kit in the automatic transmission... all it did was piss me off and chirp the tires when it went into second. Quote

It actually helps preserve it Quote
WhatTheFehl Posted February 19, 2010 Report Posted February 19, 2010 Yes but isn't it very difficult to "undo" a shift kit? Quote
Night Fury Posted February 19, 2010 Report Posted February 19, 2010 I wouldn't see why it would... Quote
slick Posted February 19, 2010 Report Posted February 19, 2010 Generally just as easy as it was to install it. Quote
xtremerevolution Posted February 19, 2010 Report Posted February 19, 2010 I'd leave it alone. You probably won't gain much at all, and it will get annoying after a while. Not to mention it will possibly wear out your engine mounts quicker. Quote
digitaloutsider Posted February 19, 2010 Report Posted February 19, 2010 Yes but isn't it very difficult to "undo" a shift kit? Our shift kits are nothing more than shims put into the accumulator to keep the springs from deadening the pressure on the shifts. They go in as easily as they come out. It's still pointless. Quote

I've read somewhere before about drilling holes in the valve body and some other shit to put in a "shift kit" ... to me that seems like ruining the transmission. I didn't like the one in the S10. I think it contributed to the pickup's dislike of going uphill... Quote
digitaloutsider Posted February 19, 2010 Report Posted February 19, 2010 Ours are nowhere near that involved. Quote
alec_b Posted February 19, 2010 Report Posted February 19, 2010 If your shifts are too soft, invest $25 bucks in an adjustable pressure modulator. Available at any auto parts store. That will allow you to modify your shift pressure (to a point). It's not as good as a true shift kit, but it will help put a little "perk" back in your shifts. I put one in my bonneville, and at WOT it greatly helped the shifts. Around town it was slightly firmer but not much. It's one of the easiest things on the car to change, the whole process should take you about a half hour, plus adjustment. Quote
White93z34 Posted February 19, 2010 Report Posted February 19, 2010 I'm 90% sure my Bonneville has a mild shift kit put in from when I had the transmission rebuilt, it helps improve clutch life as it quickens up the shifts and reduces time that the clutches drag. It is not harsh at all. Quote

jake91 Posted February 21, 2010 Author Report Posted February 21, 2010 well you just get your ass down here and obd2 swap my car then Quote
douellette Posted February 21, 2010 Report Posted February 21, 2010 Who needs a shift kit these days i have no idea what those pictures mean lol. my car is obd2, but i didnt think u could tune the stock computer on it Quote
digitaloutsider Posted February 21, 2010 Report Posted February 21, 2010 Who needs a shift kit these days You have your PCM commanding full pressure all the time???? :shock: Also, you don't want to lower the 4th apply speed that low. Keep it stock. Quote
BXX Posted February 21, 2010 Report Posted February 21, 2010 well you just get your ass down here and obd2 swap my car then Holy fuck, pay for my air fair and im there!!! Its cold as shit here in Ohio!! Quote

Keep it stock. The bottom one is my CS. Line pressure isnt controlled by the PCM (vacuum modulated) however shift time does make a difference and something I dont have shown is Force Motor Current which ive played with very carefully to firm the shifts up. Fuck up the FMC map and your likely to need a transmission soon. As for the 4th apply, are you talking about the top pic? Thats our 06 Impala which has stock shifts and everything shown Quote
RobertISaar Posted February 21, 2010 Report Posted February 21, 2010 Who needs a shift kit these days those of us that don't like the 4t65e... Quote

It is not harsh at all. do you have more details on this? or how much this particular kit would cost? As much as a few washers, a new filter, and trans fluid costs. Quote
douellette Posted February 21, 2010 Report Posted February 21, 2010 @ 3.1cutlass - what about those typical ones that modify the valve body plate? how would i tune the stock computer? Quote
