6.5 TD FSJ Conversion

[MidTNJasonF]

Back in 2006 when I visited the Mishawaka, IN AM General HMMWV plant, I was told about the proprietary mil-spec TCM they used. Memory fades, but I remember that it was not a GM sourced module. I suspect the programming was designed for the HMMWV and its rather unique roll (maybe EMP resistant) - not a highway cruiser.

Yes it is "Hardened". From My research it is a PCS (Powertrain Control Solutions) module that is installed in a very robust sealed case that is mounted in the interior cabin of the vehicle.

There were apparently several versions but many are interchangeable. There were only two chip/program variations used in various models but again the can be interchanged somewhat with no ill effects to the transmission.

The two EPROM Chip versions I have found reference to are:
CZSU and CZSW

I do not know how accurate this information is yet as it is just what I have discovered in my initial searches. I have not sourced any parts yet and I have not verified compatibility yet.

I have a lot more reading to go before I start wiring. With any luck I can track down some service manuals and or diagrams for a 2001 era vehicle and begin to fab up a wire harness. Most of the connectors should be available on the market.

My plan is to create a very simple engine and transmission wire harness to run it all. I will incorporate that into the simplistic vehicle body harness I am going to have to make for the truck itself.

I got busy this weekend on household/yard chores but I began pulling parts off the motor and separating the transfer case and transmission so the individual parts are easier to move/store. I won't get much done this week as I am off to Mexico for work so I guess I will have more time to read. That is of course if I can find some things to download and review while I am in a metal tube hurtling through the clouds.

Hello there,

I am a Senior Supplier Quality Engineer for a Tier 1 automotive parts manufacturer. A number of our suppliers are in Mexico. I have to travel there once ever month or two. Hermosillo, Chihuahua, Silao, Monclova, Monterrey, Obergon, Piedras Negras, Romita, and probably one or two locations I am forgetting.

I don't get east of Winchester, or Cookeville very often. Most of my US suppliers are in Kentucky, Ohio, Michigan, Alabama, and Mississippi. I have a few in Tennessee but mostly central TN.

We don't do anything I would call "Fun". We do interiors so injection molded components, headliners, armrests, pillar covers, and side panels. Some of them leather/pvc/cloth wrapped and some painted or film covered.

I used to make many of the parts for the 6, 8, and 10 speed GM automatic transmissions but I left that firm a while back and moved over to the Japanese OEM lines since they make more of their vehicles in the US than GM.

Hello Jason,

Middle TN here as well.
Columbia area for me. Keep us posted on the progress.
