He can get it to shift to second if he does it manually but cant get third or fourth. They were all 700R4 trannies except for the 1994, and i was looking into a 4L60E for the 1992 since i was thinkning the same thing and went to the junk yard as they were brining me the 700R4 out of a K3500 with a 350 in it.

If both nonelectronically controlled and electronically controlled versions of an otherwise similar transmission design are offered, an E suffix for electronic is appended to the designator. With the pan off, all 1987 or later units had an auxiliary valve body. Id build the heck out of it if its laying around and upgrade it as you go. The brakes and shocks are need of changing very soon and so is the steering shaft.

Give California Performance Transmissions a call you can talk to the trans man him self Art Carr. I would be scared to run with the V-6. Oh he answers the phone too.

Use the serial number located just above the pan on the passenger side of the transmission and there you'll find a letter M 700 , believe it's 4th digit. I thought they went electronic by then, but I swear it looked like a 700R4. I am not 100% but i think the 700R4 from a 2wd S-10 with the 4. My question is, The trans oil is still a bit dirty, can I drive the truck for two weeks and change the oil again, repeat this process for two months changing the oil and filter each time until the trans oil seems clean and the transmission is shifting to my satisfaction? So just about anything fulsize from 1992 back will work. On the next transmission oil change I will install a drain plug to make the job a lot easier.
