These give me warm fuzzy feelings

Do they intend to produce those indefinately?

Forget the fuzzy warm feelings, hearing them say "indefinitely" would be full-on ASMR ... but I truly do not know, sorry sir!

Pretty sure no one is going to know the meaning of that without googling. But very funny.

Transmission and T-case dropped at TMZ this afternoon! Super exciting!

 

[rabenne]

Got some pics from Tim of the carnage inside the case. 4th gone. Center diff took a bit of damage but will be salvageable for other projects. Going to use new cross shaft, neat gears, and ppg center diff housing in the new setup.

I don't want to give it a "like", what happened to cause it to loose a few teeth? Nice pictures, the last one is exactly where I need to be on my 5 speed to fix it and get my Red 90 Talon on the street again. I seem to be intimidated by the 3 rails and springs and check balls or I'd have mine apart to that point.
Good luck on the rebuild, it's in good hands.

Red dotted line is RPM, 4th gear let go around 5200 rpm on a tuning pull.

Seeing this makes me wonder if maybe I should get a PPG gearset and be done with it. I just don't want to spend that kind of money right now. Hope it all works out for you.

I wish I had. The rebuild on the evo 2 unit lasted about 12 pulls. Not a great roi. I also wish I had opted for the billet bearing plate the first time around. Also the input shaft was a bit twisted, so ya, it's probably a miracle I didn't completely trash the whole thing.

Would the bearing plate have saved it though? I'll be building a 2.3 as well so this is scary.

No way to know now. Probably not tho...

Looks like you found the rev limiter like I did when my auto let go and my son said "Man dad, you were on the limiter A LONG TIME!"
I hope you get her all fixed back up and cruisin the streets again soon!

I'm curious as boostin specifically states "tired of breaking 4th gear?" when advertising that billet plate.

I am sure it would help, right? In theory, better structural support for the bearing races would help to keep things from flexing and shafts getting out of proper meshing alignment, maybe?? Less of a problem on straight cut gears as they don't inherently produce an axial load, like helical gears do.

I just don't think it solves the problem, the fatigue life of the gears themselves. Anything above the fatigue limit is slowly (or not so slowly) killing them.

I think @bastarddsm explains it well here:

Center diff tear down photos from Tim. Everything inside the diff looks to be working as intended, shame the housing took some damage!

I don't want to go through what you are going through right now. Although this can happen at any time to anyone, I'm fairly certain I need to go with a PPG.

Yikes. What kinda power are you making...? Heck..my stock transmissions have lasted a little longer than that. I don't however do 4th gear pulls on the street. Almost never...omly at the track I pull 3rd gear teeth though.

I don't think I was making any real power when it let go, but it was a used gear set. Who knows how much time it lived above the fatigue limit before I bought the thing.

You say, "my stock transmissions have lasted longer than that"? To be fair, an evo 2 transmission with a fresh rebuild is still a stock transmission. Containing used gears with unknown histories - I should have known better, clearly! Now I am going to pony up and buy some gears that should survive my very modest power for a long time.

On one hand, it is not going to be cheap. On the other, I am extremely excited about having a TMZ-built PPG gearbox to bolt in! I can't tell you what the right move for you happens to be, but you can learn from my experiences if you think they are similar enough.

Cheaper in the long run though. I'm not looking to set records. I just want a quick, fun car I can take out when it's nice out. I'd rather over build it and have some wiggle room in case I decide to turn up the wick later. Let us know how you like the PPG.

Ouch - my drive line aside from clutch is still stock 2G GSX. I wonder what will die first?

Maybe send it in for a refresh? Get the bearings replaced if needed, or perhaps do the work yourself? My first transmission made it 1000 miles before the intermediate shaft bearing failed, locked up, and trashed the entire cluster.

Chan: do see any problem here Ted?
Ted: no
Chan: we don't have any engines Ted, no engines!!!
Chan: a couple of 4G63's would pull in a real premium 1 week before race wars huh.
Ted: yeah they would.

I've been meaning to ask you if your PPG box is still at Tim Zimmer's place getting built.
