Reverse stopped working on my a while ago, and I have finally decided to deal with it.

Unfortunately, first thing I did was pull the tranny because I was sure it was either the syncros were gone or the shift fork was bent. Once opened up, everything looked fine to me, and I was able to shift it into reverse and watch the fork engage the gear. Since everything looked good, I threw the rear housing and differential back on and re-installed it.



At this point I felt dumb, and thought it must just be an issue with the shift linkage. Stuck a drill bit in the neutral neutral hold pin hole (mine is missing the pin to just push down), loosened the clamp on the rod and the two bolts holding the shifter box in place, then tightened all 3 up. Still have the issue.

Won't go into reverse, no matter if the motor is running or not. Just before it went out completely, it would work so long as I turned the car off, put it in reverse, and started it back up in reverse already. Now, not even that works.

Is this pointing to reverse lockout solenoid? How do I test it? Is there a fuse that may be blown?
I am new to Corvettes (in the last 6 months), but not new to cars. I have never had a transmission with so many "you can't drive so we are going to make it so you don't **** up your transmission" solenoids.

Thanks,
Nick

 

im having a similar problem, what i do is use put a lot of pressure on the shifter to get it over and kinda wiggle it just slightly and it goes. it takes a lot of pressure.

someone had a thread that said it was his flywheel. do a search.

 

The lockout solenoid is "activated" when the car is moving. Being a mechanical movement, it may have locked. They are made so that IF that did happen, you can push past it. It's a firm push to get past it though. There is a special tool made to remove it w/o dropping the tranny. The dip sh'ts at GM had to make sure it is in a non-accessible place... on the top of the trans.

 

Ok, and it feels like the shifter is going into the correct location, it's not like im going over to reverse and not able to get it that far right and forward.

 

Also, if you try forcing it into reverse with the clutch in and motor running then letting the clutch out slowly, it grinds.

I tried bleeding the clutch..... and even if it was the clutch not being adjusted correctly, wouldn't it engage when the car was off?

 

My car (2006 z) is having intermittant problems engaging reverse. when I get it in and release clutch it shakes a lot and doesn't back up I was told it was the reverse lockout mechanism and fixing it requires dropping the tranny and that they (Kendall Chevrolet) wouldn't cover it under warranty b/c I have motons, stoptech brakes, and race seats! estimate is $1700. I said no way and am going to another more reasonable dealer.

 

You may need to re-align your shifter - may want to try these instructions on the forum. Could be a faulty reverse lockout solenoid. I don't think this problem relates to the flywheel.

 

Called D & D they said if you can put the shifter into the position for reverse and that it shakes or grinds, that it is not a reverse lockout solenoid but a clutch disengagement issue. bringing mine in tomorrow to chevy

 

My original post states I already did the shifter alignment.
Wouldn't reverse lockout solenoid prevent me from putting it in the gears position (or even all the way to the right of the H)?

I don't see how it could relate to the flywheel at all.

Thanks for the info. I'll try messing with the clutch linkage a bit.

 

anyone know if there was a TSB about this issue?

 

Alright, I have confirmed it is a clutch disengagement issue.... so how do I adjust the clutch engagement? The master linkage is not an adjustable threaded rod.

 

New clutch fluid...


Seriously...


I've been there, the full story is in another post of mine where I responded to some dude with similar problems.


Beat on your shifter to get it into reverse and you can probably get a bent fork like I have...


I'm living with it since I can get it to work, but it's definitely not working like it did when the car was new, and I know I'm going to have to have the trans pulled again to fix it...


I really wouldn't doubt that you're going down the same road I've gone on...I already wrote this story at least once...simple solutions can help...


Have a good one,

my car is at the dealer now, tranny is being pulled as we speak will update you guys.

 

Wrong... clutch is bled with fresh fluid.

Make sure to let us know. I'm pretty sure mine is my clutch not disengaging because....
I did an experiment, went on a hill and rolled backwards pretty fast until I was able to get it in reverse. Once I was in, I was able to hit the brakes and upon letting the clutch out was moving backwards! It was amazing, haven't been able to do that in a couple months.

So I basically need to figure out how to get the clutch to dis-engage, and why it doesn't go in when stopped.

 

Got my '06 z back. it was the reverse synchros--- worn very badly. replaced 5th and 6th synchros as well since it was difficult to go into 5th at 160 mph. car goes into reverse perfectly now. clutch was ok, fluid was ok. remeber my car would go into the position for reverse but would just grind at times
