Was wondering if anyone else had this issue, and if the bushing kit and mounts would help solve it. Seems to pop out of only 4th Gear at high Rpm 5k+ not all the time kinda random, the shifter feels like it goes under some serious Vibration [harmonic] when it pops out. OR if my 4th gear blockers are trashed also it is HARD to get to go into reverse, so i know the Reverse Syncros are going. Ive rebuilt a few Tremec 5 SPeeds TKO trans in my day so i know what to do, just asking to see if anyone had a issue like this and resolved it with the bushing kit or mount kits. Cause my mounts and bushings are all stock 53k miles on her now, aftermarket LOUD *** CLutch thou.

 

what clutch?

 

Previous owner put in a ACT, its been in there since i got the car @42k miles and havnt had any issues with it, other then it being very chattery at idle.
