I just bought my 68 Camaro and it will not go into reverse. The PO says that it "used to work". I have never had a car with a muncie trans and I don't know where to start looking to fix it.
The chilton manual does not say much about it.
Anyway, long story short, the gear shift lever will not move over to the left far enough to then move it up into reverse. I did get under the car and manipulated the linkage and it seems that it will work if I could get the lever to go over far enough to engage it.
I did not want to dive in an tear the linkage apart without asking first.
The first thing is to put the shifter in neutral, get under the car with a 1/4" drill bit and see if will slide through the holes in the three linkage arms and shifter bracket. If it doesn't, adjust the linkage so the drill slides smoothly through. I had to make this adjustment a couple of times to get it just right. What is the proper way to adjust my Hurst four speed shifter? Here's the info from the Hurst website.
There is a 1/4 inch hole at the bottom of the Hurst mechanism that runs through all three levers. This is called the neutral alignment hole. To ensure proper adjustment, run the shifter from first into second and then back to neutral. Insert the neutral alignment pin (or a 1/4 inch drill bit) into the neutral alignment hole. If the 1-2 lever interferes with the smooth insertion of the alignment pin, remove the 1-2 linkage rod from the shifter and thread the adjuster button either in or out to eliminate the interference. Repeat this procedure with the 3-4 lever and reverse. To adjust the stop bolts, back the bolts out of the shifter frame until only a few threads remain. Push the stick firmly into third gear and hold. Screw in the stop bolt until contact is made. Release the stick and back the stop bolt out one turn and tighten the jamnut. Push the stick into fourth gear and repeat the procedure.
Thank you for the adjustment information. I will try that out this afternoon. I looked up Muncie on the internet and found exploded views and other info but no information about adjustments.
I will have to look up the Hurst site (I didn't think of that one).
Thanks again for the info.
The Hurst shifter adjustment procedure above is dead nuts accurate!.....This info is in my old Chiltons book also!.....Anyway, when my car was a project and I was assembling the clutch linkage, I did not have it adjusted properly, I mean, it would go into 1-2 and 3-4 but clashed really bad while trying to position it into reverse gear!....A little more adjustment on the clutch solved that!.....Also, keep in mind, you may have to wait momentary, as the gears are still spinning with the clutch disengaged, while shifting into reverse gear!
Another thing to consider here is that if it is physically blocked from moving far enough to the left is the possibility that the shifter's adapter plate is not correct for the shifter mechanism. I had to fabricate a plate for my M-22 in my 69 Camaro and ran into this very thing. I had to go back in and mill out the slot for the rod inside the shifter to slip into when in the reverse position. Hope I explained it well enough to be understood as this could be the issue.
Ok, here is where I am at now. I adjusted the linkage with the 1/4" drill bit and that seems fine. It shifts from 1st to 2nd just fine and from 3rd to 4th just fine. And neutral is easy to find.
The gear shift will still not physically move over far enough to the left to be able to push it up into reverse.
I disconnected the reverse linkage and pushed on the linkage from under the car and the transmission goes into reverse just fine. No problems with the transmission so the problem has to be in the linkage somewhere.
With the reverse linkage disconnected the lever at the shift assembly can be moved back and forth with no resistance. Is this supposed to happen???
I am wondering if there is supposed to be something that engages this lever when the shifter is moved over to the left, but is just not engaging???
Maybe I did not put the 1/4" drill bit in far enough to engage the third lever??? I will have to look agian.
I have never adjusted the clutch. I have only had the car 3 weeks and it is not registered or insured yet so I have not been driving it. Also I am doing all of these adjustment with the engine off and the car up on jack stands.
I hope this is written in good enough english to be understood.
Thanks for the input it gives me more things to try out to get this fixed.
