I have a 99 convert. & stick shift and it wants to pop out of reverse at times. Is there an adjustment I can do to help stop this problem???

Been wondering about that myself- mine will do that sometimes when parked. Never had it happen while car was moving.

There is no adjustment per se. A forum member sent me this (see below) for my problem which is the same as yours. It did not work for me. I can say this with 98% confidence to fix it, the tranny has to come out. I never had mine fixed. (it got totaled and I don't have it any longer)

Good Luck




I had a problem getting the MN6 into reverse. Tried double clutching and going forward first but sometimes even when it went into R it would pop out.


This is my version but it is in the GM shop manual as well:

I installed a Ripper and questioned the pin that hangs off the bracket on the front of the stock shifter but it was not mentioned in the Ripper install instructions so I put it in the Ripper box with the stock shifter in the attic with other stock takeoffs. Loved the Ripper but reverse might have been a bit worse. Read a post which I can no longer find on this alignment procedure so I took the console apart again and did the procedure and like a miracle I have never had the slightest problem since. Reverse like a real car! I think it was C4C5 Specialist who suggested it. You will have to remove the console and engage the pin found stored on the front of the shifter mechinsm into the shifter rod and down into the rod that runs back to the trans. If before you do this, you remove the pin and the holes are not perfectly aligned you have the problem. The shifter should be in its "natural" 4 gear centered position when checking. With the pin in, loosen the four torx bolts. I think there are three that are on the casting (one shown in picture) and one that clamps the rod to the trans. You do not have to remove the shifter which is removed in the picture. With these loose the shifter can self align. Tighten the bolts, remove the pin and try shifting. If all is good reinsert the pin loosen the bolts one at a time, torque and locktite. Once all is tight pull the pin try it out. I would drive it before putting the console back together. If you want to try this procedure I will scan my Ripper instructions which show you how to get console apart. There are a few tricks. If you ever wanted a Ripper do it now and save an hour or so. Let me know if I can help.

Before you go into overhaul-mode, try this;
You should notice that similar to engaging 1st gear, there is a sort of "double-notch", where you really have to have the gears lined up to "fully" engage reverse. If not, and you are only in the "first" part of the gate, it can and will pop out under load. I only had to have this happen one time to me in 1st to make sure it never happened again.

So to review, you may need to move forward a bit to line up the gears to fully engage reverse. If you are indded sure it's all the way in when it pops out, then I agree, you have a mechanical issue.

Tranny problem, not a shifter problem. Good Luck.
