Hello,
I need help from my ZHP aficionados. First and reverse gear has been popping out of gear in the last month. I am positive the gear is fully engaged. The odd part the behavior is inconsistent for example the shop bucking the car by letting the clutch out fast in 1st gear without it disengaging. In some cases, it will pop out of gear under light throttle load and other times its fine at 3400 RPM under medium throttle. No issues with 2nd to 6th gear is fine under full throttle.
An audible pop sound [although no grinding sound] can be heard when the transmission decides to disengage.
Does anybody have any ideas that would cause this?
I'm really hoping I don't need to replace the transmission.

* (Mid April 2021) - Shop installed Autosolutions short shifter, Rouge transmission mount, Guibo replaced, and Driveshaft CV joint
* (~ First week of May) - 1st & Reverse gear popping out of gear
* (~2nd week of May) - Issue occurs more frequently
* (May 19th) - Car sent to shop and is able to reproduce the issue
