Truck is a 1993 HDJ81 with an electronic A442F.
Here's the breakdown:
I had my injection pump rebuilt by a reputable shop and re&re'd by my normal guy (I just don't have the time to pull this otherwise I'd do it myself).
Since the rebuild (which went well) my torque converter lockup, which is controlled by the O/D button on my shifter, won't engage. The O/D light flashes, but due to a series of miscommunication the shop pulled the light bulb so I couldn't 'read' the code.
Thinking it was the solenoid, I replaced that, then thinking it was the ECT (I found a cheap one) I replaced that, and still no love.
So I'm wondering if there is a mechanical or electrical connection that got either missed or mis-installed on the injection pump that directly affects the O/D and the lockup of the torque converter.
I've attached the diagram from the IP that says "Governor Assy, Torque Control" which is where my brain is leading...but I poked around last night and everything looks good.
Anyone got any ideas?
