I have been doing a lot of searching on this and was wondering if you old xj jeepsters could help me out
This is what i know (or think i know)
The Jeep AW4 is made by Asian Warner and is remarkably similar to the A340F
internals and solenoids similar a340H (tcases aside)
The Jeep AW4 uses a transmission control Unit (TCU) to regulate all solenoids.
The solenoids are very similar (possibly interchangeable with a340x's)
here is the question...
I am about 2 weeks away from putting a 1UZ in my 1994 4runner, can I wire an AW4 TCU to control my transmission (a340h) instead of having the 1UZ ecu try and interpret/send the incompatible signals? This is a wiring diagram for an AW4 with Economy/Power switch similar to our transmissions.
AW4 TCU inputs:
12 v (switched)
Iíve seen Lextreame.com uzswap.com but never heard anyone speak of this option. Am I just thinking about this wrong? Thanks!
