I was wondering if anyone knows the NSN for the GM transmissions?

NSN = National Stock Number

6th gear

If you have fed-log downloaded on you a MSD handy at work than you can look it up by that. I am assumeing you are in the millitary since you are asking for the NSN.

I am not in the military, but know a place that can order from military surplus. Only issue is everything is by NSN.

I'm an active duty Marine, and I'm pretty sure that none of the military vehicles currently in inventory have 4L60Es or 6L80/90Es. Some of the old Cut-vees (blazers I think) had 4L80Es or turbo 400s. Most of the Vans and trucks that the military has are serviced by outside dealerships. I know we aren't allowed to do ANYTHING (even change oil) on our vans and GOVs. HMMMVs are a different story though.

Humvees use 4l60s

Which transmission is being used depends on the year Humvee you are referring to. H1s had 3L80/TH400s, 4L80Es; H2s had 4L60Es (which explains why we did so many repairs on them in Iraq). I'm not entirely sure on the 6L80Es, as I haven't worked on them in a while, so I may be mistaken. I can look it up and see what I can find.

TH400 NSN 2520-01-161-2136

4L80E NSN 2520-01-489-0850

That's probably all you're going to find. the TH350, 700R4, 4L60/65E and 6L80/90E's have no military application... yet. I looked all over hell and half of Georgia through my newest Fedlog disc, and all the GM part numbers I had didn't cross to anything. Good luck.

All military HMMWV's are H1's. The A1 model has the TH400, the A2 model has the 4L80Es. A1's had the NA 6.2's or 6.5's, the A2's had the Turbo 6.5 hunk of *****. When were you working on H2's? I worked on some Chevy trucks, Suburbans and even a few F350s, but never any non military Hummers.

Oh, and I think you're talking about CUCVs. We finally just got rid of most of them in the Nat'l Guard. They ALL had TH400's behind an NA 6.2 or 6.5 diesel, blazers and pickups alike. Bummer too, those things were AWESOME!

I. Know for a fact some humvees use 4l60es/700r4s, we pulled one last week out of a 998
