Hey guys I'm new to the forum. I just bought an M1008 two months ago and haven't had any issues with it until the other day when I believe 3rd gear in the tranny went out. I need to replace it asap and I'm not sure of the exact specs and what tranny I need. I know it's a turbo 400 that's it. Any advice or info would be greatly appreciated!

Blown transmission in M1008

Check your vacuum to the trans first before you call it quits, Loss of third gear will usually mean a weak reverse as well. The 4x4 400 does not interchange with the two wheel drive version, you will need to find a replacement with the same output shaft length as yours or have yours rebuilt if need be.
Pull the rear end cover, could be a G80 taking a dump with those symptoms....
It does sound like a G80 taking a dump, but an M1008 should have a 14BFF w/ Detroit in the rear. G80 units were just used in the M1009 Blazers.
So it has repeatedly locked up in 3rd gear? And continued to drive afterwards?
That sounds kind of terminal, should be evidence of catastrophe in the pan, an inspection is advisable.
Sounds like some bands went
Two bands in a 400, one is low reverse, only applied in reverse or manual low, the second is the intermediate brake band, only comes on in manual second and helps slow the direct clutch drum down.
Ah. I had a jeep lose od and it was a band. Then noise then catastrophic failer.
So It would need to be rebuilt then right?
It sure is looking that way. Pull the pan and have a look first though
Don't do a fluid flush.
Depends on the shop and the parts used, warranty etc. Anything from $800-$1200 on the bench with converter and upgrades would be expected
That's definitely out of my budget at the moment but thanks for the info. I'm gonna have to go used.
