94 4L60E -Compatibility
94 4L60E -Compatibility I'm wrapping up a build on a 4L60E for my '79 Cherokee LS swap. I found this thing in the mud at the local junk yard, brought it home, ripped it apart, found it to be all new inside, proceeded to add a bunch of Sonnax parts for Level 1/HD truck build, molded pistons, some bushings, etc.
I am not certain what year it is. It has the 93-94 TCC valve, no PWM solenoid for the TCC. The 3-2 Solenoid is the new (on/off) style. The pressure control solenoid looks current.
My plan is to finish putting it back together (once my new '94 separator plate and shift solenoids arrive) and run it behind a 4.8 with an adapter flex plate, new torque converter for a 94 k1500, and use the 00 or 02 pcm to control it. I was going to keep the harness inside the trans that it came with and modify the engine harness to have ~25 ohm 5 watt resistor to simulate the TCC PWM solenoid.
Thoughts, challenges?

You have a couple options.
A. just get a TCC solenoid, plug it in, and let it sit in the pan.
B. Turn off any codes for TCC in the pcm
C. do what you've described
Sounds like you understand the issue and how to fix already. Kudos

Can you just set it to no error reported in hp tuners? I did some searching, but couldn't get the full story.
My internal harness doesn't have the connector for the solenoid, which is why I was thinking of going external.
Thanks!

I was going to say yes, as I've done that before...but I got to thinking and I've just done it on mismatched solenoids, not missing ones.
So...I can't say with full certainty.
I don't see why not.
The On/Off solenoid for TCC should work the same, and the shift noids/epc should work fine.
As long as you set to no error reported, I don't see any reason it wouldn't work
