Hopefully the no-reverse is caused by low oil level.
If not, you can try to fix it by replacing the solenoid.
I read this whole thread, I found no more than 3 posts when the person said that replacing the solenoid fixed the problem.
By the way, TCC stand for torque converter solenoid, so it's not really
the "reverse solenoid", although it can cause a no reverse condition when defective.
