Ok, so i've been trying to give my new mechanic [and that depends on how this is all resolved..] some time to dive into my issue and he doesn't believe my issue is in the cv joint since it's only locking up when i go in reverse.

Anyone know what would make an NV-T350 [A578] transmission lock up only in reverse?

It has had the proper fluid for the past 3 years and i've changed it twice by my own choice/boredom. Last time was 8 months ago.

umm well you do know it has a differental on the side of the transmission u may have knocked the pin loose at one point and its causin that to lock up or u have took out some splines on the cv shaft which u could pull it out and look

 

Transmission locks while reversing cause just because the lock pin might got corrupted, so by servicing lock pin results as a solution to this problem.
