AW4 question

[Eagle]

I have an '88 2.5L, 4-speed, 2WD Comanche. I'm undecided between replacing the 2.5L engine with a low-mileage rebuilt and a 5-speed, or converting to an AW4 with the engine job. I have the AW4 and a 2.5L bellhousing and torque converter. I don't have a 2.5L TCU.

 

Is there a difference? Can I use a 4.0L TCU with a 2.5L?

The TCU doesn't care what the engine is. But I don't know if the harness for your 88 2WD w. manual transmission has the TCU connector built-in. Also, the TCU had slight pinout variations over the years.

I have parts heaps -- an 87 4.0L auto, and an '89 4.0L auto. And I have the electrical manual and a soldering gun ...

 

Frank Swygert, a retired AMC engineer who was active on the OLD old XJ bulletin board (the predecessor to NAXJA) had a 4.0L with AW4 running in an AMC Hornet. He controlled the tranny manually, with a 6-position rotary switch connected to the individual solenoids. Anything is possible.

I remember Frank well. Very sharp guy. Passed many emails back and forth with him picking his brain when I had questions. He always had the time and the answers. Is he still around?

Frank was doing an AMC subscription newsletter a few years ago. A good information resource.   I got it for a couple of years, then dropped it when I joined jeepstrokers.

 

Pete, I assume you are aware of the manual shift AW4 options that are out there.

Guess he's AMC retired.

Well, found he is still posting on theamcforum.com

I thought I remembered that he was a retired AMC engineer, but his profile/bio says he retired from the Air Force. Wrong again, eagle -- that's at least twice this year, and it's barely more than a month old.
