CGT tranny problems

[Craig D. Niederst]

Looks like the clutch is gone on the '86 CGT. My brother, who drives the
car, reports that car would not move when put in gear and clutch was let
out. Strangely enough, he had the car out last night, and everything was
fine. I tried to move the car just a few minutes ago, and he is right, the
car basically does not go when the clutch is depressed. It does move
slightly, but basically just revs when given gas, so not enough to be
driven. The only symptoms of a problem in the recent weeks was the basic
total loss of reverse (I posted on this before, basically you put the car in
reverse, let out the clutch, and the car immediately pops out of reverse.
This problem has been there for months, but it has gotten noticeably worse
in the past few weeks), and a slight, occasional grinding (maybe 1 in 10
shifts) going from 2nd to 3rd. Besides that, the tranny has been OK. I have
no record of the clutch ever being changed on this car (now has 195k on it),
so thats why I say clutch. Any other items that could cause this type of
problem? I see the clutch slave on the top of the tranny, could a bad one of
these cause this (I thought the clutch was mechanical, not hydraulic?)? How
difficult would a clutch replacement be on a CGT? Is pulling the tranny a
DIY job for someone without a pit/lift? I would need to be able to complete
the job for a couple of hundred bucks (i.e. price of parts), since thats all
my brother can afford, so taking it to a shop who would want probably $1000
or more for the job is out of the question. Any advice is appreciated. TIA.
