Bought a used 85 700r4 that was advertised as a 91. It's a used remanufactured one with low miles. I gave $700 delivered. Is the 85 ok or a turd? I was hoping to get the updated one, but it might be futile since I bought it out of state. Going in my 83. The one I put in earlier has no 3-4 gears so I get to swap transmissions again. Yay

typically you want a 88 or later it has the auxiliary valve body and most all the improvements they did on the 700r4 to make them reasonably reliable. the aux valve bodied cases have the st louis arch in the casting making them easy to identify.
You must be registered for see images attach


82-87 had a bad reputation however if updated when rebuilt they can be good to, but will not have all the updates the 88 and later did. Now if you got this from a rebuilder who can't tell the difference between an 85 and a 91 I would not have a lot of faith in him IMHO.

:sorry:Someone caught this is actually a 4l60e without the throttle valve cable. however the arch is what i was trying to point out here was used in 88 up 700r4 and the 4l60e versions.

Salvage yard. That why I wanted the later model. I guess someone put an older one in a 91 k1500. I can tell it has been redone just looking at it, but like you said I wanted all the updates. I'm just afraid I'm SOL. I'm going to call tomorrow and see if I can get an exchange or partial refund

Moto, sell what you got and get a newer case. 88/92. Make sure the case has the arch like in the pic with the 4l60e. if you see a connector plug like in the pic, dont buy it. A 700r4 has a kick down cable.

Yeah, that's not a 700r4 at all. 4L60-E all day long. Try to find an 88-92(93) yes there are some 93's in 700r4 too.

I don’t know about towing and spending a long time behind more than stock motors but my daily driver, right now more of a long haul driver, uses a 700R4 that would have come off the line in around October 1985. I drove a thousand miles in it this past weekend, and I’m at 288K with no rebuild. Granted, you don’t know how a used one has been treated, quality of rebuild, etc., but I’m constantly surprised at how smooth this thing still is even though it’s behind a Wee-Oh-Five as HRPC calls them.

No, not at all. Shifts perfectly, doesn’t leak, fluid maintains normal color. The torque converter lockup can be screwy when there are drastic temperature changes, usually in the spring and later fall, but I don’t count that. @CorvairGeek is in the same boat. He’s probably in the mid-low 270s, unrebuilt, and that’s a 1984 model 700. I never expected it to make 300K, but I expect it to breeze by that now so we’ll see what things are like at 325K.

Glad to hear someone has good luck with them. I can't say I've had for any length of time but they worked with a couple of wierd clunks here and there but they worked.

I thought was getting a 1991 version. That's what they advertised on Car-part.com. and it's going behind a badass 350. Well the opposite of badass.
