Ok, A stern warning on my bone headedness of running a Tune from an unknown tuner. Lol

Either way the issue was self induced on my end and I did not take it to heart.

If the transfer case is in bad enough shape, it can cause the output speed sensor to read incorrectly. That can cause the transmission to shift strangely, but shouldn't cause higher temps.

With how heavy you use the truck, I would look into at least a mild build on the transmission. Get a good converter (MikeL can recommend one for your turbo & use case), updated clutches, and the valve body mods to remove the pressure knockdown in lockup. I would also consider a bigger transmission cooler while it is down. MikeL used to sell a kit that is very well regarded, not sure if he still does. I pieced one together with an aftermarket oil cooler from Jegs, and it has served me well.

Just make sure you use large enough lines or you will actually make temps worse, as the transmission will bypass the cooler if it has too much restriction, resulting in NO cooling. And don't bypass the cooler in the radiator, you just replace the stock aux cooler with a larger one. You absolutely need the cooler in the radiator, as it sucks down a massive amount of heat.

Depending on where you are in the US, there are a handful of good transmission shops that will put together a solid Allison build. MikeL is the goto for the southwest, and we can get you recommendations for other regions.
Thanks bud, Im in Idaho

If you keep losing fluid at the back of the tcase yoke, you need to inspect the driveshaft yoke. Its a common problem to get grooved from the seal and leak no matter what seal you put in the t case.
Replaced with a brand new driveshaft last year this time, for I thought the same thing and my driveshaft had thrown some weights and needed rebalanced... Since the truck is leveled and lifted about 3 inches, I had one custom made with new GM yoke... But I will double check that again.

Bump

For my application should I pay the extra money for the Billet Shafts
I can get an Input, and Output, and a Main?

Considering price of build, which one of the three is most applicable?

Thanks in advance

I'm at 660+ HP to the tires and on all stock shafts. You'll break the P2 planet before a shaft it seems, since I ate one of those, and the C2 hub. It seems your goal is below my power level (if I recall correctly), so shafts would be a waste of money IMO.

I'm literally out in the garage right now assembling my transmission, haha.



I only went with a billet input for one reason: so that it doesn't snap off inside the converter, and thus pissing $1800 into the wind. My brother lost a converter with a broken input on his 4R100. I've heard of it happening with the Allisons as well.


So I just went with it for peace of mind. Doesn't sound likely that you'll break any of the shafts under 600 rwhp, but it was worth the extra $600 to me to know I won't take out a part that costs 3x as much if it does break.
