T5 experts help
We rebuilt my T5 about a year ago and I have put about 1000 miles on it and it worked great up until a few days ago! I was on the highway in 5th and it stopped working
! Well I knew right away what the cause was, but why would it do it I dont Know.
The 5th gear driven gear pushed the retaining ring over the splines on the mainshaft and it just slid back? I think I just got a reject snap ring . They are thick hardend steel I dont know why it would stretch that easy unless it was a dud! I have it fixed and it workes great again but I am just worried about it doing it again. does anyone have better answer?

Transmission: Completed
Axle/Gears: ones that turn.
Only reason I can think of would be the clip wasn't properly seated when the trans was re-assembled, but I'm sure you checked that.
Or maybe a slightly larger snap ring was used, and it worked it's way off?

Did you use a pair of inside snap ring pliers when you removed the ring? The reason I ask is that if you muscled the ring off and on it may have streched beyond its failure point. It may not have been noticeable at the time, but the stress caused it to weaken and eventually fail.
I always use the right pliers, and then squeeze the ring with a pair of slide jaw pliers once it's seated to make sure that it's fully locked. I've yet to have a failure with this method.

That's not right.... IIRC the teeth are cut in such a direction as to tend to pull the driven gear the other way, up against the bearing.... you might want to see if you can run yourself down another set of 5th gears (drive and driven)

I thought about this one for a while and came up with another possible solution.
It may have nothing to do with your gears at all. It could be a shift linkage problem. The 5th/Reverse shift mechanism in the trans is tricky to get back together, and it isn't entirely uncommon for that big torx head bolt to back its way out of the case, which would most likely cause a problem just like you mentioned.
Regarless the trans needs to be pulled and the problem determined. Make sure that the threads for the torx bolt are good, clean, and apply some locktite on reassmebly. It's cheap inusrance, even if that isn't what turns out to be wrong.
