No Reverse...
Hey guys
I have been fighting this for awhile. I have no reverse...[I]ts not even selectable and cannot be forced in...its like it doesn't exist. I have a 2001 Z06 wit an M6 RPM style built tranny. I have tried adjusting the Tick master and once before this helped and reverse was smooth as silk but then was gone again after a short while. I fully replaced and bled the master as well as replaced the reverse lockout solinoid. I am getting 12.06 volts to the wiring on the ;\lockout solinoid so this is not the issue. When reverse was working it never grinded and felt fine. Now its been gone for a few months with no ryhm or reason. No sure what to check next. I have a dual ACT clutch and B&M Sport shifter as well. I do notice that ever since replacing my tranny from the M12 version that my shifter has 2 nuetral positions and gates are further apart but the tranny seems fine other than no reverse.
Tranny has
carbon syncros
billet keys
bronze pads
steel shift fork
cryoed gears
cryoed 30 spline output shaft stock is 27 spline
please let me know what you think as this is getting very frustrating,
thanks

It's the shifting fork that lost the plastic tips that fits into the shifting collar groove. Had it happen to me. Look at this pic and see the black plastic tips? It's a crappy design.

And since it does have to come out......R&R your clutch,flywheel,pressure plate, slave cylinder since it's right there.
Edited: But I see you just installed new clutch and stuff, so ignore my advice on the clutch and flywheel.

If it was a clutch disengagement problem, I'd think you'd have a problem engaging first too.

I just finished installing a clutch 3 times after having engagement/disengagement problems. I measured the distance between the fingers and throwout bearing after discovering it was slightly out of tolerance. I made a .065" sheet metal shim and placed it under the slave. It calls for a space between .100 and .225". Doing that moved the point of full engagement, but it still wouldn't shift into reverse. The way to tell if you have an engagement problem is to jack up the rear, start the car, push in the clutch, put it in 1st and if the wheels turn, your clutch is dragging. Another test I did was to try to put it in reverse and while holding the shifter in that attempt, I would turn the car off. It would pop right in with the car off. I was warned that the clutch manufacturer would test it, replace everything, but tell me there was nothing wrong. After getting the replacement back, it worked perfectly.

I would try adjusting the bushing that ties the shifter in to the shift rod before pulling anything. I had the same issue and solved by adjusting the bushing. I found it to be VERY sensitive, took several attempts to adjust properly.

No, there is a sleeve behind the shifter that couples it to the rod that goes to the trans. The sleeve is adjusted with an allen wrench and controls the pitch of the shifter and the feel of the gates. Mine moved a bit to the left towards first gear and I could no longer shift into reverse. Loosen the allen bolt and move the shifter left and right and you will figure out where it needs to be to get all gears shifting/feeling proper. One other note, how tight you lock down that allen bolt also effects the feel of shifting. Took me about half an hour to get it right but my car shifts so much better than it ever has. I spent five years literally muscling it into reverse with two hands and thinking it was a clutch dragging problem.

Drew,
I expect that even if the reverse lockout solenoid were broken, it would still let you engage reverse with the car turned off. I have seen the collar come loose on the shifter adjustment before, but that only created a situation where you had to push it hard over to the right to engage reverse. RagtopWS6 (aka Rick Kim from RKT56.com) is a supporting vendor and one hell of a trans builder and great guy. You might PM him for ideas as well.

The collar I am talking about is the same regardless of the shifter. When my collar came loose, as you reference, I physically could not get my trans in reverse, not possible. Depending on how you adjust the collar radially, you can lock it too far in either direction and loose 1st/2nd or reverse. Definitely an easy 5 minute deal to check it before he pulls anything apart.
Sounds like you're talking about an aftermarket shifter.

Also try aligning your shifter again and see if that helps.
If not, I would look at Bret's suggestion and pull your inspection plate and check the air gap on the clutch as it could be dragging some.

The same thing has happened to me (no reverse with car off or on), just after installing an aggressive cam, I suspect the increased vibration has moved the collar.
Is that the allen key bolt you use to adjust the sleeve on the lower right corner of the picture below?
