TH700r4's from 82-92 and some 93's just needs TCC wiring. A simple switched +12v circuit.

4L60-E's are totally electronically controlled. I've seen hacks done to get them to function 'computerless' but then are fully manually shifted.

Shift *kits* re-calibrate the valve body. TCC lockup is not controlled by these.

All of GMs "E" trannys must have the computer to operate them as an automatic. If you don't run the computer you have to replace the valve body (and some other things) to convert it to a full-manual shift tranny with fixed line pressure. Its not easy to convert it backwards to a non-electric transmission because all of the hydraulic/mechanical things were removed and replaced with computer controls; governor, servos, some valves... Its just not feasible.

But, the 700r4/4L60 is basically the same transmission, but with all mechanical operation. The rotation guts in most cases switch over all the way up through the latest 4L65E, so you can have the best of both worlds; better rotating guts of the later tranny with the simplicity of the non-computer tranny.

Upgrading a 700r4 isn't cheap, but retro-ing an "E" tranny is not even really possible.

I just wanted to verify with you guys the casting number : 4YP004B..just to make sure I am dealing with the 700R/4l60E. So basically I would be better off to go get a standard 700R4?????...is the length/mount the same as I would rather not move my transmission mount.
Thanks again

Well, I don't have casting numbers committed to memory but the E's have a round multi pin plug on the passenger's side.

TH700R4's have a 4 pin square plug on the driver's side. A few '93's had a 5 pin.

Same pan.

A 4 hole / pin electrical connector on the dirvers side indicatres a 700 / 4L60 trans. No computer needed to operate the trans or the lock up converter. There are ways and kits to control the torque converter lock up clutch.

A 4L60E has a electrical connector on the passenger side , about 1.25 inches in diameter. The 4L60E requires a computer to shift automatically

correct me if i'm wrong but 700r4/4l60's have a tv cable where the "e's" don't.

A photo of the 4L60E electrical connector:




4L60E would need a computer to operate in an automatic shifting mode.

Tomslik... the fellow is confused about electrical hook up on the trans indicating that the 700r4 trans will need a computer. This is a common misunderstanding.

And Yes , Tomslik the regular 700r4 trans does have a TV cable ... some folks do not understand what that Cable is.
