They are good born warner trannies. I would go for it if you are thinkin about a swap or somethin. If in fact it does blow, you can have it rebuilt, like in that ebay photo above. They are strong durable trannies.

ummmm, i don't see a stock T-5 lasting longer than 5 minutes behind a stout motor like that. i have a Trick Flow headed 355 w/ 10.2 comp, and the tranny is already on the way out, after just two weeks. i told myself i was gonna be nice to the thing, but it's just a force of habit to rip each gear as hard as i can. these things DONT take abuse very well at all. Slicks are a huge no no, as are hard clutch drops and power shifts. If your extremely nice to it, it'll last for a while, but it's still gonna grenade sooner or later.
Now, there are several people who have had good luck with them, all the way into the low 12's high 11's even, but far more people are dropping them in the mid 14's
Good luck,
Eric

You are looking at about $800 to get one rebuilt if you take it out of the car and drop it off at a shop. Not a lot to do to make it stronger. I rebuilt mine myself for around $500.
Your best bet is to try a T56 or Tremec 3550. The Tremecs are durable, but are a little harder shifting transmission.

Yeah, I am pretty vertain that is a joke...
The transmissions are nice and smooth shifting, but the countershafts are too weak to handle any kind of abuse.
Typical problems with these trannies are you will break teeth off the main drive gear on the counter shaft, this cause wear on you input shaft gear and a slight wobble where the input shaft attaches to the output shaft. That wobble then eats up the race on your output shaft and you wind up replacing almost all of the trannie...

Could the tranny be the vibration i have been getting in my car since a (fairly tame) 350 went in? No vibration untill you go over 3000 rpm in gears 1-3 (not 4, 5 or neutral)..
That just a dead tranny or something else?

I have an idea...
Since a lot that I've read states that case flex is the main culprit behind the gears breaking, why not just dip the case in molten steel and let it harden? Sure, it'll add a couple hundred pounds, and probably won't help, but it would sure be *******...
Seriously, someone could probably design a girdle that goes around the tranny and prevents case flex. Shouldn't be hard to install, either. I wonder...

flex is only increased with the torque arm
I got an unrebuilt T5 behind my 400 and (for the time being), it has not broke. No factory TA though.
