transmission type poll
As most of you know, I have a 84 suburban with a 350 motor. I know the 700r4 transmission needs rebuilding. I do a lot of towing with this suburban and am deciding whether to rebuild the 700r4 trans, or put in a 350 trans with a 9 inch tailshaft.
I am letting the majority decide for me on which one to go with. Thanks for the help Tommy Davis

Not wanting to loose the overdrive, just wanting to know which one would be better on the heavy towing it will be going thru. I am not too familiar with them, so I thought I would let the ppl here decide for me.
Thanks for the help. Looks like I will try to get the 700r4 rebuild. I know it is a 85. Is there other years I should look at that would be better? I am not running any emissions and am not sure what all I would need to install it after rebuild. Tommy

If possible get a 1988-1992 year 700R4 from a K-truck (4wd) and have it rebuilt.

You can update your 85 transmission with later parts. But I would just add extra clutches in the 3rd-4th gear, add corvette servo, .500" boost valve, shift kit setup for towing, good transmission cooler and a lockup kit so you can lockup the torque converter in 3rd gear. You could also just get a later model valve body too I think, thats the only real difference bewteen the early and later model transmissions, I don't remember if the valve bodies interchange though. You could also upgrade to a heavier sprag but for our year 700r4 its kind of expensive because the whole thing needs to be replaced, also the sun gear shell can be replaced with a stronger unit.
How much weight are we talking about here?

Not sure on exact weight. I do know my wife has a 26ft trailer loaded with her flea mkt items. Just want to be prepared if she gets more in there.

Do get a newer style 700R4, don't bother updating yours. It should be cheaper to just buy a core newer model and rebuild it instead of updating the old one.

Rebuild any core from 85 and up. I have an 85 and beat it pretty good. No problems with a stout rebuild.
