Re: 6-speed trouble (kingvet)
I found out it was the clutch slave cylinder the resevoir had gone dry. Put some brake fluid in it and it shifts like a dream. Looks like I'm buying a slave cylinder now, guess that is what happens when a car sits. :rolleyes:

Re: 6-speed trouble (kingvet)
I just went through this with my '89 ZF.
Refer to

Then do the following in the cold car:
1. Check the fluid level in the resevoir. Check it's color and if you can see the level and topoff as necessary (the fluid for my car is is dot3 hydraulic fluid, same as in the brakes, your may be different as noted above).
2. Inspect the underside--trans housing on the driver's side to see if there is a stain (that is the slave cylinder location).
3. In the interior of the car, put your fingers in the slot in the carpeting where the cluch goes into the firewall. If it is wet that means that there is leakage from the area of the master cylinder. (I had leakage here, but it turned out the previous owner must have removed the caps from the cylinder and it leaked down the firewall, but there was no damage, they just didn't top off the resevoir)
4. Start the car from cold in N, Pump the clutch several times and then try to put it in Reverse. If it goes in, that means that the master is probably bad, since you "pumped" up the pressure. (that is also why it will go in the second or third time when the car is warm.)
5. None of this precludes a clutch replacement. If the pressure is low and the forks can't be moved to the right position, the clutch will wear abnormally.
I think that is everything--but be sure you look at the website, I printed it out and gave it to the chevy mechanic and he told me the info was better than that provided by GM. Like knowing to change the trans fluid in the ZF every 30K with Castrol 10-60 w motor oil (the same oil run in BMW M-6 engines.)
Good luck
