ZT3- transtrem does not lock solidly -?adjustment possible

position there is a tiny bit of play up and down, maybe .010" - .025". This can
produce buzzing - vibration of the entire movable part of the trem - on certain
The TT3 trem locking system consists of two blocks; each with serrated teeth that
fit together. One block is connected to the movable part of the trem; this
block can be moved either toward the headstock or toward the endpin by a cam mechanism
attached to the trem arm. This movement allows the user to either lock or
unlock the trem by rotating the trem arm. The second block is screwed to a static
bottom plate beneath the movable part of the trem.
The movement in my TT3 is occurring because the serrated block on the movable
part of the trem is not fully engaging the mating block that is screwed to the static
bottom plate of the trem. In the "locked" position there is a tiny gap between the
mating teeth of both blocks that allows movement.
There are two screws that hold the second block to the bottom plate. I've tried
loosening these and shifting this block closer toward it's mate. This worked for
awhile but soon things shifted back to their original position and the problem
Is there a way to adjust the cam that's controlled by the trem arm to push the
movable block a little further out so it's teeth engage the static jaw better? Any
BTW, I've tried contacting Gibson several times about this,and haven't had a reply.
Most dealers have no idea whatsoever on how to adjust these things and would only
offer to sent the guitar back to Gibson; for a nice 1-3 month vacation!
Does anyone have any suggestions on how to adjust the mating of the movable to
the fixed trem locking blocks on the TT3?

Don't have an answer to you your poroblem but maybe you can help me with mine? The 2 blocks with serratted teeth - has the one mounted to the body got a similiar ammount of teeth as the trem one? I ask this because I bought a ZT3 with transtrem problem and the block in trem cavity looks like its broken. Thanks and hope you solved your problem

The "big plastic wheel" adjusts the spring tension and thus the position of the trem when not locked. This is why the setup process starts with the trem locked in zero position (E) - tune - unlock - adjust the tension to match locked and unlocked position.
If your trems are really broken or defective, you need to find a "Gibson authorized service provider" in your area. These are the only ones being able to sell Steinie parts.
