I'm a huge fan of GearVendor's stuff. Unfortunately, they don't work with full time 4wd's like mine because the bolt on after the transfer case, not between.
You are right though, that 5/6 speed Allison box is danged 'spensive!!

are you running a civilian or military truck???
If I was you (being a HMMWV mechanic) I would suggest using the factory t-case that is hooked to the allison if it comes from a chevy truck...do plan on shortening your already short rear driveshaft...your best bet would be to PPE and talk to them about the duramax/ally swap they did into their HMMWV...

Oh man, I've seen that PPE truck. I would give ALOT to have mine done up the same. Unfortunately, it would cost about as much as my whole H1 cost me. Serious cash, but serious fast!
Might just have to do that someday.

hi just so you know the allison tranny is a lot larger then the 4l80 and heavier your going to have to in large the tranny tunnel and make some way to mount it have you looked into the new 6L90 theres one on ebay item # 290349904482for $1500.00 for 4X4 check it out might be the way to go.

Tranny tunnel on a H1 is about 3 foot wide! Plenty of room in there. Thanks for the idea and link. The 6L90 had not even hit my radar. I searched around but I dont see any way to get it to shift though as it its an electronic box. Did not see any aftermarket ECM for it. Will keep an eye on this box though.
Cheers!
Cheers!
