Default 1995 6 speed question

I had $4500 worth of transmission work done by the corvette paramedics in mount holly NJ. I got the car back and there is no reverse lock out mechanism in place. They claim the 1995 corvettes do not have any type of reverse lock out mechanism. I only had the car a short time before I had the work done, but I could swear it did. So I am wondering if any six speed owners can help me solve this mystery. If the car does come with this feature then I urge you not to use this shop for repairs. If it doesn't (which I find hard to believe) then I am mistaken. They returned my call once claiming it didn't exist. I contacted a ZF specialist in arizona and he said it absolutely does but they refuse to answer or return my calls.
If there is a lock out does anyone know if it can be fixed without removing the tranny?
:cheers:

The only reverse lock out mechanism on a 95 is a spring that resists the shifter from going over that far in the pattern. There is a lock out mechanism on earlier models, but I believe it stopped in 93 or 94.

Do you know if I can replace this spring by just popping off the console cover and locating where it is supposed to be on the shifter........or is it located inside the transmission itself? Either way, there is nothing to prevent the shifter from entering the reverse gate which makes 5th gear shifting a problem. thanks

I replaced my shifter with a hurst, I didn't see anything that I thought was a reverse "lockout" spring. I assume it is in the transmission.

$4500 :eek: :eek: :eek: what had to be done????

I don't know about 95's, my 94 has a deal you have to lift up on.

My car would sit a long time if these trannys are that much to fix!

Early ZF's had a ring that had to be lifted to engage reverse, later ZF's did not have the ring. I don't know the year break. You may find some information on http://www.zfdoc.com

Expensive to fix, darn right. Why do you think we get such long posts about the correct lubricant to use in these things? Folks are concerned and wish to make a correct choice.

1994 was the last year for the lock out ring, my 1995 doesn't have it, it has the spring type of lock out.

*Note* If you have a B&M Ripper shifter, there is no reverse lockout at all, no matter the year.

According to the ZF Doc, 89 thru 95 had the lockout. My 95 doe`s not. I believe 95 and 96 have the "crash thru" version. :cheers:

What was the reason for the rebuild?

No lockout on mine either. It should as noted in some of the other replies the '95+ have a "detent" spring that requires an extra effort push toward the passenger side to get it into reverse. Most of the transmissions Bill Bodreau works on are out of ZR1's I believe - perhaps the ZR1 kept the lockout on all model years, and hence the confusion over '94 or '95.

I had a '95 model ZF6 in my '91 Z28. It had no lockout ring. '94 was the last year for it.

4500 dollars worth of transmission work was due to a bad synchronizer. Once they opened it up they replaced the gear set, some synchronizers, replaced all the seals and I had them throw in a clutch while they were at it. A remanufactured tranny from gm is 6500 and brand new is 10k. So take care them because they are $$$$$$$$$$$$$$$

Wow the price of these things blow me away!!!

If a 700r4 is so much less, then that should make a zf6 car worth lots more!
wishful thinking I know!

A new tranny is more than some of our cars will book for! That is ludacris!

Makes me not a little worried about power shifting my car so much!

My 95 does not have a lock-out; only a "crash thru" If the current makers of the T-56 would make a T-56 to replace the ZF, they could make a mint. It would not be to difficult to mod the T-56 and we would have a better and far cheaper tranny. Sid.

I had my ZF rebuilt late last year and from talking to Bill B, http://www.zfdoc.com, it sounds when they rebuilt your tranny they did not get the detent spring back in place. From what I recall this is further in the tranny than the shifter. It has been awhile though.
