1991 Trooper reverse gear problem

Hi there:

Could someone be kind enough to help me with the following question?

Everytime or most of the time when I try to put the trooper in reverse, it tends to refuse to enter reverse gear. So what I do is to put it into any other gear and then try the reverse. This usually works. What could be the problem that it doesn't shift smoothly?

Thanks for your help!

I have this problem sometime also,

I belive it is due to.

1. RPM to high ( 8000 is normal)
2. Check throttle return

I can't remember the rest but I have a helm manual with walk throught I could check if you would like.

I definitely would appreciate if you could get me some more info on the problem. Thanks!

I will look up the information and post it for you. I have to find my book because I just moved that is why it has taken me so long to reply.
