Curlybandit Posted May 28, 2005 Report Posted May 28, 2005 I searched the forum and found one mention of the Shiftplus for the 4T60-E. Just wondering if anyone knew if this would make a difference in the 4T60, and if it's even worth it? Thanks. Quote
SleeperRed90TGp Posted May 28, 2005 Report Posted May 28, 2005 So what are you talking about a shift kit for the internal trans or a shifter.? Trans-go makes a shift kit for the 4t60 called the 4t60 jr or something like that. You defiantly have to take the trans apart. About 50 from everybody. Jud Quote
Curlybandit Posted May 28, 2005 Author Report Posted May 28, 2005 The second item down is what I was looking at. ShiftPlus Vacuum Shift Improver Part #SPVSI Quote
scorpion_x9 Posted May 28, 2005 Report Posted May 28, 2005 I bought an aftermarket vacuum modulator that is adjustable for about $20-$30. And it does the same thing as that Shiftplus, except you can't adjust it while driving. Quote
Curlybandit Posted May 28, 2005 Author Report Posted May 28, 2005 Did you notice any difference? Is it worth installing? Quote
THe_DeTAiL3R Posted May 28, 2005 Report Posted May 28, 2005 I once disconnected and plugged the vac line from my vacuum modulator on my 1988 GP (2.8). This way it shifts as hard as it can, but I didn't notice ANY performance improvement. I took it to the track and could not tell a difference between plugged vacuum line or plugged in the modulator. All I DID notice was how damn hard it shifted from D to R/ R to D (if you were rolling at all), and when it downshifted was very hard. Quote
