Reverse when cold?

Does it grind the gears when attempting to engage reverse when everything is cold?

If so, then I believe your problem is actually that your clutch is NOT disengaging all the way, even though the slave may be moving all the way. When the pressure plate is retracted, the clutch plate should move on the splined shaft away from the flywheel and allow the tranny input shaft to stop.

If the plate stays in contact with the flywheel, the input shaft spins, grinding non-synchro gears and making it hard for synchro gears to engage (since the synchros are trying to stop the shaft to allow engagement).

This could be due to grit or improper grease being used on the splined input shaft, or a build-up of clutch debris and whatever lube might be on the splines. NO grease (only graphite powder) should be used on the shaft.

If this is happening and reverse engagement grinds, you are wearing your synchros at an incredible rate. Expect failure within 10,000 miles.

If slave travel is normal, and the clutch is NOT fully disengaging, you need to pull the tranny and fix the problem PRONTO.


Lately I have had trouble putting my car into gear (manual tranny) when it's cold. I have to let it warm up before I can put it in any gear, and shifting is almost impossible for a while. After about 15 min. or so of driving (usually around town only in 2nd :( it will gradually get better to the point where I can shift it almost normally (albeit a bit stiff). If I drive the car a lot in any given day it will get to the point where it's normal. Would a worn clutch cause this? Does anyone have any experience with similar problems? I'd appriciate any feedback. TIA
