Tranny slipping? Or is it? Help!!!!

[racerex]

I have a 91 awd talon. I bought the car knowing the clutch was bad. Well we took the clutch out and it looked new. Instead of doing the job 2 times I went ahead and installed a new clutchplate, disc, and bearing and sent the flywheel out and had it turned. Reinstalled and what do ya know....Same problem. So after reading I adjusted the clutch both ways... same problem. So someone said the clutch isn't releasing so I put a new hose between the slave and c. master. Same problem. I put a new slave cyl. and c.master and bleed it today to rule it all out. GUESS WHAT>>>>>Same Problem. I can start the car and put it is 1st gear and let the clutch all the way out. to car will make a small jerk but then idle with the clutch released and in first gear. Rev it up and it will start to engage. Take it out for a drive and dump the clutch from about 2500rpm and you hear a whine then it grabs and smokes the tires after a second on slipping. What could this problem be? I have yet to smell the clutch buring. Can something in the trans do this? I hear no popping.....Just the whine. Please help....Out of things to replace. WTF

Are all 3 differentials stock?? Also, how many miles are on the tranny and has it ever been rebuilt?

Yea they are all stock. 120,000 miles. Could the viscous couple do this. I was just in the garage with the car on the lift and the rear wheels do NOT spin at all running in 1st gear. They don't even try.

The 1G clutch pedal assembly is known to wear out over time, check it for freeplay.

Recently a car was brought to me that had the trans removed and installed. The person complained that clutch was slipping. He stated when he stepped on the gas in 3-5th the rpm's and speedo would rise bought car didn't go any faster. Upon inspection I found that the right front outer cv joint was not assembled. Meaning the shaft was not in the joint. The boot was there tho with no visible exterior damage. Had he continued driving it would have burned the center diff up. Upon reading your post I would assume the center dif is now junk and I would pull the front axles and examine them.

Yea I checked the freeplay and it is ok. I will check out the diff and axles next. I have a spare VC I picked up today so I will try that juist to rule it out. If it doesn't fix it. Out comes the tranny AGAIN!!!

Yeah, that was my initial guess too. But if he slowly took out a diff, I think he would feel it. I've taken out my front diff before, and it was violent. I experienced excessive bucking and noise and then shortly after, the car would not move. Every tooth on one of the gears had been completely sheared off so none of the power was being transfered to the half-shafts.

Now, you say his diff may be junk, what exactly could have happened to it? I mean, how can you slowly ruin a stock diff other than shearing off the gear teeth?

Update......Transfer case has no teeth at all left on the gears. Shinny and smooth. Hope this will cause the symptoms I listed. I realize it is problem with the rear wheels not spinning. But I don't know if it is the cause for the slipping condition? Wouldn't it just drive the front like normal or would the diff be trying to put the power to the transfer case since the gears were gone and there is -0- resistance? I will have a new transfer case next week just wanted to know what you guys think.

Yup, there's your problem.

Same thing happened to me, but I only have one diff (FWD) so my car wouldn't budge. At least you still had your front wheels powered..... Replace that, and your problems will be solved for another day....
