Crazy K Posted January 16, 2006 Report Share Posted January 16, 2006 this is a 4t60 tranns, 4t60e attached to 3.1 came out in 93. I think it should have a vacuum modulator. Quote Link to comment Share on other sites More sharing options...
Prospeeder Posted January 16, 2006 Report Share Posted January 16, 2006 that could be ur problem, lol, might wanna get a Trans Vacuum Modulator, thre around 20$ from like shucks or where ever, there adjustable, and just need about 2 turns with a very small screw driver to adjust, soo is there just a gapping hole on the trans or did some1 block it off?

THe_DeTAiL3R Posted January 16, 2006 Report Share Posted January 16, 2006 The 4T60 in my 88 had a modulator, and the 4T60e in my 95 has a modulator. Although I would think that not having one would just cause really hard shifts.. Quote Link to comment Share on other sites More sharing options...
1QUICKHATCH Posted January 17, 2006 Author Report Share Posted January 17, 2006 well I have not spent alot of time in the car untill today and noticed that its not a 4t60 its a 3t40 :oops: my boss lent me a dealer plate so I could take it down the road today and found out that it will shift at like 4000-4500rpm (60-70 km/h) :? so I am going to adjust the kick down cable and see if that lowers the rpm it shifts at! thanks to every one that replyed.
