I have one under the bench from Carlisle last year. Haven't gotten to it but wondering how it went for anyone else?

Bump to the top if you don't mind....

I'd at least crack it open and make sure all is well, I saw them there last year .

What is the date on it ?

I believe it was late 1980's - I thought I would at least stick a new front pump seal in it. The case in my car has some stripped threads and a a few other issues so I liked the fact of starting over with a new shell.

Other than not knowing what the calibration of the Valve body is it's an unknown ?

the seals are all 20 plus years old so a reseal through , and an internal inspection to get a good idea of clutch counts and planets would be the minimum.

If you like how your current trans shifts/drives you could dupilcate it's interanl clearnaces and swap the VB over and have a fresh case.

I have helicoiled many holes in the last few transmissions I have rebuilt , as many as 30 in one case that was matching numbers to a car and welded up a crack and a hole in it.

Those 727's that went into the M880s and M882s were extra HD. The army bought thousands of them and spec'd them so that they could handle to requirements of a tactical vehicle. They needed to withstand the harsh pounding they got. The M880s and M882s were the precursor to the HMMV

What's the part number stamped in the pan rail below the shift lever?
