Transmission failures!

Agree... why not? Not mandatory and useful for extending life of hard parts.

And I like being out of practice rebuilding T56s.

Sean I agree heat is the main issue. I installed a cooler for Hallet and was happy with result

[Sook]

I agree with it as well. I also lost a trans at Hallett near the end of the last race, heat related IMO. I'm going to try to heat shield the exhaust pipes passing near the transmission at the very least.

Sean are you running the T 5 or T 56? Good luck getting that to pass when they won't allow you to run an aftermarket aluminum diff cover on a weak GM rearend but they will allow you to swap it out for a 9"?

Tyler made the T5 go BOOM! Just ignore the fact I was driving and it was a 2-3 shift coming out of The Bitch a few weeks ago. I think it made 3 years-ish behind the LS motor...

T-56 going in for Nationals.

I'm impressed and surprised the T5 lasted that long. Seems most or all of the Fords have abandoned the T5.

Are you going to submit an RCR to allow that toyota transmission? Hah.

1 minute google search came up with a t56 kit. https://www.bowlertransmissions.com/...-pump-upgrade/
Then here is how to do it. http://www.pozziracing.com/Bowler%20...il%20pump.html
But Mark Stielow says it's needed above 450 hp.

Maybe allow it for the T5 if that will keep them together-is it legal to put the T5 in a fourth gen?

Personally for the T56 I don't think it's needed. What kind of fluid are you running and how often are you changing it? Have you had it analyzed? I don't think it should break down at 250 but I'm certainly not the one to know.

Change?
Never analyzed - would be a good time with the car now a project.

Late model ZO6 Corvettes and Z/28 Camaros have internal oil pumps to provide external transmission cooling. On the Z/28 the cooled oil is also run through a heat exchanger in the differential cover, then back to the transmission. When asked about T56 cooling needs, Camaro great Mark Stielow indicated a track driven T56 starts needing transmission oil cooling from around 450rwhp & up. Those driving Road Course events with high horsepower engines should incorporate transmission cooling to extend the life of their transmissions.

Late model, i.e. not the stuff we run. Apples to apples we should add a cooler.
