will a 92 4L60 automatic swap into a 87 Vette?

will a 92 4L60 automatic swap into a 87 Vette?
I know that the kickdown cable is different.
Just use the 87 cable?
any other differences?
a 4L60 is just another name for 700R4, correct?
Thanks

..... If the transplant donor is a Corvette then its straight up ... Non Corvette transmissions have a longer tailshaft by 5/8" ... There may be some speedometer drive differences but that would be solved by swapping the parts from original to the replacement ... on the '85 , the torque converter has different splines on the input shaft , so just use the converter from/for the newer trans .....

I'm pretty sure the 85 had a higher stall rating than the later cars, so if you'd be interested in keeping the higher stall re-use the converter from your 85

Yes, 700R4 same as 4L60. I believe the 92 trans is going to have a round electrical connector that needs addressing. Also, in the interest of accuracy, these transmissions did not have a "kickdown cable". It is a throttle valve(TV) cable.

Be careful make sure its not a 4L60E the E= electronic means a computer controlled transmission.
I was going to fit one in my 85 was a reco box real cheap, ended up the 93 onward is a 4L60E witch needs a computer to control it. Was going to cost around $500 to get a controller module to run it , ended up i got my T700R4 rebuilt instead.
Make sure you can tell the difference between them.
See link to an aftermarket 4L60E controller below.

A 93 Vette transmission is not a 4L60E

This is 'correct' !!
The OP needs to be able to correctly ID what it is that he's actually anticipating to use. If he can't it could certainly be an 'adventure'.
In post #6 it was pointed out the connector could be different. This certainly is the first 'visual' the OP needs to confirm. OP never mentioned what the donor actually is. In post #3 output shaft length differences are mentioned.
If it's thought to be an untouched/original 4L60 the ID on the case rail could be quite valuable. Previously reman'd/rebuilt = WAG

The new transmission is a 1992 Corvette 4l60 (NOT an "E")The new transmission is an original with 50k on it.It has not been rebuilt or messed with.It is bone stock.
The new transmission will be installed in a 1987 Corvette.
The new 1992 transmission will be installed with its original 1992 torque converter.
What I am mainly interested in is:
The wiring of the 4 pin and 5 pin connectors and if there is anything else that needs to be done with the wiring.
Thanks

The transmission itself is a direct swap, the wiring connector could be swapped between transmissions. Torque convertor input splines are the same between a 1987 and 1992 so you could use either convertor. Check the speedometer gears and make sure the parts are the same, if not swap them. The 1992 was calibrated for an lt1 so it will shift at higher rpm then the 1987 so you may want to swap the govenor.

I'll post some connector information a little later but this is how I'd think it appropriate to accomplish what you need.
Perhaps arbee will comment!
EFI sells the connector - they've recently changed their web presence and an old link I had didn't work so this is newer and should.

It's way less expensive from vendors such as Mouser or Del City. Just search 12034342. You need to be careful when ordering terminal though, this is typically a 'female gender' terminal device but in this instance it requires 'male gender' terminals. Terminals should be a local purchase making sure you buy sealed or possibly you could un-pin the car connector now and just insert into the connector. You should get some 'cavity plugs' for the unused cavities. I'd think local also. A fleet truck parts supplier most likely or maybe NAPA.
