Re: Update
Ok, I was fishing for a physical limitation on the shifter stick
itself. A body lift can cause the shifter to bind on the boot. I think
I mentioned mounts before too.
My T-5 acted like that when the tranny got GL4-GL5 'compatible' oil in
it. I changed out to semi-synthetic because it was the only oil I could
find in a GL4 with no limited slip additive or 'friction modifier'.
So if the clutch appears ok for the rest of the gears except the lower
ones, reverse is a 'low' gear, that implies something is spinning up
the tranny input shaft.
The next suspect is the pilot bearing. Lots of folks forget the pilot
bearing in the flywheel needs a good grease job when the clutch is
done....

Re: Update
Ok, I was fishing for a physical limitation on the shifter stick
itself. A body lift can cause the shifter to bind on the boot. I think
I mentioned mounts before too.
My T-5 acted like that when the tranny got GL4-GL5 'compatible' oil in
it. I changed out to semi-synthetic because it was the only oil I could
find in a GL4 with no limited slip additive or 'friction modifier'.
So if the clutch appears ok for the rest of the gears except the lower
ones, reverse is a 'low' gear, that implies something is spinning up
the tranny input shaft.
The next suspect is the pilot bearing. Lots of folks forget the pilot
bearing in the flywheel needs a good grease job when the clutch is
done....
