[91RCSBsilvy]

If you give me the last 8 of the VIN I can look it up.

can you tell me what my tranny is? last 8 is MZ193990

 

[MIHELA]

Yep, that's an HM290.

what would be the best replacement if im going to do mostly bolt ons and a lift and daily drive it?

If you're still doing all those bolt-ons, I'd run a t3 exh turbine on each side with a t4 intake turbine. When doing your search for them, use the term "hybrid", that's when you mix different sized int/exh turbine housings.

 

[MIHELA]

You could go with a later NV3500 96+ has stronger parts, or an NV4500. If you want to break new ground you could try to fit one of those ZF S650 transmissions from a GMT800 heavy duty. Unfortunately 4wd is limited due to having to be able to bolt up a transfer case.

i have a nv3500 and i have no ploblems with it holding the power...the only thing i had that wouldn't hold the power is a 10 bolt

 

[91RCSBsilvy]

would a nv3500 bolt right up to my current t-case?

When did we start talking about hair dryers?
