2008 GMC YUKON HYBRID Transmission/from AZ

@NickTransmissions

would you happen to know of any way I can find out if a 2wd one of these trannys can be converted into a 4wd to bolt the T case on it? I've looked all over online and found nothing. I'd buy a manual if I could find one.

I keep seeing posts about 6L80s being quoted $7k to rebuild these days, there's a 2wd hybrid one local for 600$. I have no way of testing it, but he says it came from a running truck. feels like it can't hurt to have in a corner if I ever need it.

Unfortunately, I don't at the moment (not for 100% certain, anyway) but will be going to my transmission parts supplier this afternoon so will ask to see what 2ML70 stuff they have and level of effort to convert (though I suspect is just an extension housing assembly swap since the output shaft and rear gear train are all nested w/in that extension housing kinda like a Chrysler 42-48RE).

Will post back later this evening with what info Im able to gather and we can go from there.

@j91z28d1 - no luck at the parts place. The only thing they sell is a filter and gasket for the hybrid trans. They haven't seen a core come through in about 5 years so couldnt tell me what all had to be done for the conversion.

thanks for asking.. I'm not surprised at all that they haven't seen one in a while. low production numbers and I believe most out live the battery and the afm stuff leading up ending up in junk yards before the trannys gives up. I'm just hoping to keep mine for a very long time. I have seen a few posts here and there that did sound like a motor or something went bad and not just a bad diagnostic blaming the tranny for failing undersized prius batterys in a 6k lbs truck haha.

I get the feeling if this one ever goes, I might have to try my hand at rebuilding haha.

You're welcome, man.

It will make for an interesting rebuild project.

Another issue is the X175 connector getting backed out pins OR chafed wires near the parking brake area

Causing a No start or NO shift condition
