Funny, my car sits at a dealer right now with the tranny in repair.

They are starting with the reverse lockout soleniod and plunger. The other items, trouble getting into 1st and reverse will be looked at after reverse lockout fixed.

You may want to do the z06 clutch, flywheel and slave replacement while they are all apart. The cost for all of this through Luke is rumored to be less than 675 for the parts as needed. There should not be much in labor extra, since all that is different is the flywheel and replacing the slave (some extra work needed to bevel case).

If my trans is bad I hate to be that far behind in the waiting list!
Good Luck!
Sorry didn't see your other thread.
