fleetwoodguy79 Posted November 22, 2004 Report Share Posted November 22, 2004 I'll try to explain this as best as I can! I dont know if its slipping, or not having enough vacuum pressure. First to second normally shifts fine, but when it tries to go into third, its like it shifts into neutral unless you give it some throttle then it will START to shift. Sometimes you can hear this grinding noise when its shifting into gear, VERY strange. 3rd to 4th is perfect and the tq. converter locks up after that just as it should! And when I take turns, if I'm accelerating, it tries to find a gear like no other! Slips, grabs, slips, grabs... Is it a vaccuum related problem?? Or is my trans about to die?? Any help would be greatly appreciated guys! Thanks! Quote Link to comment Share on other sites More sharing options...

95 3-4 Posted November 22, 2004 Report Share Posted November 22, 2004 Sounds like tranny is cashed, you could try replacing the vacuum modulator since its cheap and easy, costs about $15, and is right on the front of the transaxle by the drivers side radiator fan. Its a round tin can a little shorter than a beer can , also with car running the vacuum line that runs to it should have plenty of vacuum signal, a thumb over the tube is all thats needed to test signal Quote Link to comment Share on other sites More sharing options...
fleetwoodguy79 Posted November 22, 2004 Author Report Share Posted November 22, 2004 Sorry bout that! 94 GTP Quote Link to comment Share on other sites More sharing options...
Regal_GS_1989 Posted November 23, 2004 Report Share Posted November 23, 2004 Yea, thats why I wanted to know, you got a 4T60-E, so there is no vacuum controls on that tranny at all. Your problem would most likely be caused by an electrical problem. I doubt that it would be slipping that bad, if at all. Quote Link to comment Share on other sites More sharing options...
95 3-4 Posted November 23, 2004 Report Share Posted November 23, 2004 My 95 3.4/4T60E has a vacuum modulator on it Only electronic trans I've seen with a vacuum modulator, the 4L60E and 4L80E dont use it Tv governor controlled transmissions are way easier to troubleshoot and have a longer service life than electronic trannies, thank god for technology Quote Link to comment Share on other sites More sharing options...

95 3-4 Posted November 24, 2004 Report Share Posted November 24, 2004 GM's Hydra Matic has always built good trannies, I was very suprised when this 4t60e went out of the 95 @ 108k, I thought it was the strongest link, seeing as the 3.4 has no power 92 Regal parts car has 4t60 and it has 200 and its just starting to slip and the 3.8 in it runs like a dream Ford automatics are usually quite thrashy, I love my aod but would never want a e4od, a4ld or 4r100 or 5r100.

Regal_GS_1989 Posted November 24, 2004 Report Share Posted November 24, 2004 Tv governor controlled transmissions are way easier to troubleshoot and have a longer service life than electronic trannies:lol: I agree with that, my 89 GS has 377000kms (235650miles) on it. It's all original, never been rebuilt. The only thing that is a little touchy is if you give her in reverse, than it will slip just a bit.

z34_nut Posted November 24, 2004 Report Share Posted November 24, 2004 i'm telling you right now, its all on how you maintain the vehical. you could prolly make either the 4t60e or the 4t60 last almost if not more then 350,xxx/ that is if you take care of it and change the fluid in intervails.

95 3-4 Posted November 24, 2004 Report Share Posted November 24, 2004 The 92 Regal parts car I have has 200k on it and 1st is starting to slip, 95 GTP has 108k and its completely gone save for 1st, I dont believe either had any type or normal transmission maintnance With transmission I think alot of the life has to do with how it is driven, if you have wot shifts all the time that tranny will be fried real quick, with normal acceleration they last alot longer grandma driver last for ever, quick shifts help also, a long sluggish shift wears the friction clutches out quicker. And if you have 70 or 100k on original tranny fluid you better not change it or plan on changing trans soon cause that fluid is the lifeblood of that tranny with all the friction material flowing in the fluid maken it grab, in a high mile trans that has had good maintnance 8oz of Ford Trak-Lok friction modifier isnt a bad idea The aod in my Mark is great it has 71k on it, I really ham on that car and tranny, but rwd trans are easy to rebuild and the aod is one of the easier rwd autos, I have never touched thm transaxle but now that I have one to check out I will do so. I did notice the rebuild kits for the 4t60e is like $350, damn aod or turbo 350/400 rebuild kit is $90 Next car will have a t56 and a snake on the side Quote Link to comment Share on other sites More sharing options...

95 3-4 Posted November 25, 2004 Report Share Posted November 25, 2004 Yea a built aod can handle a helluva lot more power than that weak azz "world class" t-5, and the t-56 is 2 grand, a built aod is 1 grand w/ transbrake I like the manual shifters but autos are more consistent at the strip Quote Link to comment Share on other sites More sharing options...
