2ML70 Rebuild

[Knagawa350]

Alright so tested all the way through on a new neutral safety switch, it never gave me reverse lights, so it is a BCM issue. My scanner is not solid enough to figure it out, I’m sad to say she was towed to Chevy for a full diagnostic this morning. But by the weekend they will be able to tell me where I f****d up. Will relay their information as it comes.

hopefully they get you up and running without being to expensive

Well they’re charging me 300 for diagnostic, and I’m sure it’s something stupid I forgot to plug something in or something. They’re also doing the airbag recall finally too, which I forgot about and was wondering what was taking multiple days, they had to order the replacement airbag.

ahh well while I'm sure that's annoying. it could be much much worse. I don't have much faith in dealers with this trucks. so that they were able to fix it without wanting to sell you tons of parts is a very good sign

They still haven’t told me what’s going on with it yet, but like I said I’m willing to bet money that I missed a step somewhere electrical. They are waiting to diagnose it for when the airbag arrives.

Have one ? Where did u find the o-rings that go into the drive motors? Have mine torn down now and the o-rings are past the point of using due to swelling

They have to be replaced no matter what the swelling is part creating the seal when the fluid get put in. EVERY PART is carried by SMC performance, I ordered everything from them for my rebuild. The o rings aren’t listed on the website you’ll have to call them:

Better yet DM me I ordered 10 and only used 4. I can probably ship you some just as quick. I literally just ordered everything except electric drive motors new. And if you need help on reassembling, some shit is out of order if you’re following alldata I’ll give you my cell number

Thanks I’ll try calling in the morning if they don’t have them I’ll get ahold of you.

They’re out of Michigan and they are only open Mon-Friday in that time zone 8-4 I think

I forget if I asked already or not, in your research did you find any difference between years of trannys. I know they changed the aux fluid pump from 08,09 to 10. anything internal?

mines a 11 and there's a 09 caddy local that got crashed, looks clean I was going to contact them about picking up the tranny for a spare and maybe the gauge cluster, cause they look kinda wild.

any clue about the 2wd or 4wd being able to be swapped around by changing the tail shafts?

you're kinda then only one that's had hands on inside of one, at least this late in time. maybe some dealer techs did when new, but long gone info.

I just saw a youtube that popped up on my feed of a shop trying to fix one, and said they couldn't get trannys or parts. so the truck went to the junkyard. such a shame.
