If you do purchase another transmission, I'd be willing to go through your trans for a very reasonable price to try and learn what is going wrong with 5th gear synchro. I plan to do this to my trans when I install our stronger straight cut gearset.
Ensure you're using quality fluid and that the shift gate to reverse isn't causing a slight misalignment.
Thanks,

Yeah I wanted to open it up when I build the trans! It's annoying that this car as so many problems after boost. Might need those gears sooner! haha

We went with the mixture after looking at the specs for the factory specs, and the Motul stuff. We were aiming for a low temp viscosity that was just a little less than factory, to help with the cold weather operation. I haven't had any troubles with shifting in anything from 5 degrees to 40.

Good to know! Yeah I might try another fluid this week and see how it goes. Hopefully it helps because I like my 5th gear on the freeway!
