Yet another transmission question

[Eric Wettschreck]

I smoked the 700r4 tranny in my truck not too long ago. 89 chev, 5.7, 4wd, 1/2 ton.

I've been looking for one and not having the best luck finding one fairly local. I've been able to find a few from 90 sububarns. I know the 700r4's have evolved over the years with numerous improvements. My question is will a 700r4 from a 90 suburban 4x4 bolt into my 89 truck?

Anyone know??

Without a doubt it will bolt to the engine, and if it has the same transfer case in both vehicles it should be fine. My information shows 1989 through 1992 is the same.

Sweet. Thanks again Mac.

Looks like I know what I'll be doing next week. Good thing the garage is small and the heater doesn't work very well.

[Macgyver55]

Like I said, make sure they have the same transfer case and it should be good to go.

Where did you find one?

[Eric Wettschreck]

Nordstroms in S. Falls.

They don't want the core but I'll be bringing the burnt out one along for comparison. I was going to re-use my old transfer case. Isn't it the tailstock that makes the difference? I'm not too familiar with these trannys.

I have done many of these. Just make sure you keep your mount that bolts to the cross member. I have seen 3 differnt styles.

Not trying to be too annoying, but here's another question. And, I should add I'm only asking this after doing some reading on the internet aboot these transmissions.

I only have first gear and reverse. If I put in drive it will not shift out of first at any RPM. Dry road or slippery doesn't matter. There is no vacuum modulator. I don't see anything ripped off this trans.

After reading up a bit I'm learning the governor controls quite a bit, and they have a habit of shearing their gear. Since I have the truck in the garage thawing out will all intentions of swapping a tranny out tomorrow I'm thinking about pulling the governor first and seeing if there is any noticable damage to it before I yank out an entire trans. Have any of yous guys swapped out a governor on a 700r4? If so, what should I be looking for when I remove it?? I figure since if all else fails, this trans is coming out, but, if I don't have to pull the whole thing I'd rather not.

Thanks.
