Bought the car used and the seller said the clutch was replaced. Car has a self adjusting clutch and slave that does not need bleeding. There is a slight drip from the overdrive unit, yet it has plenty of fluid. Although the fluid looks more black than red. The manual portion of the transmission has plenty of fluid that looks to be in good condition. It does not matter if the overdrive unit is on or off. Also, it seems like the clutch gets harder to depress as the car gets hotter. According to the specs book, the car should run between 190 & 255 degrees. It typically runs between 170 and 205. Any suggestions as to what the problem might be?

Sometimes folks replace clutches and let the trans hang on the shaft of the trans which can bend up the new clutch like a warped record album while they tighten up the trans. NOT good. It may not be that but it does cause problems. Not sure how temp sensitive that would be. Nail the clutch hard to the floor and if it gets easier to shift that's an area to look. Always support the weight of the trans until it has at least one bolt tightend up, T 86vette New User Aug 23, 2006, 8:10 PM Post #3 of 4 (3593 views) Re: 4 + 3 Transmission Problem Sign In Yes there does seem to be enough (proper) play in the clutch. If the clutch is warped I would think there would be some noise. There is no noise, odd sounds, or smells coming from the trans. This seems to be a very strange problem. Tom Greenleaf Ultimate Carjunky / Moderator Aug 23, 2006, 9:03 PM Post #4 of 4 (3592 views) Re: 4 + 3 Transmission Problem Sign In A warped clutch disk should make noise but just woudn't work well. Sometimes they shake or chatter (an unsmooth feel) but if you feel decent freeplay that probably isn't it. I think I would change out the gear oil(s) for new and go synthetic and that may make a big difference. The new oil(s) should work as a cleanser and if you notice a difference do it again later and you may avoid something expensive, T   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
