The controls were the same as what was used on the 1992/93 6.5 trucks...Possibly the Mil stuff may have been a tad more robust. Just a TCM is all. ...

Robyn: I'm curious as to what the military Humvees use as a transmission control with the mechanical pump and 4L80E. ???

These trucks have the 4L80E Transmission The mechanical injection pump was far better and was used in the MILITARY stuff The DS4 electronic...

PCM is Powertrain Control Module. Its function on a HMMWV M1152 would be minimal, if it has one (I don't know. Maybe?). I have no idea what might be...

Seller does state upgraded PCM, not PMD? Mechanical fuel injection is better for what reasons? I am taking a look at it tomorrow. Anything else to...

Unless it's been updated (downgraded, IMO), it should have mechanical fuel injection. No PMD.

Sorry, meant Humvee 1152 & is 24V. Why does it not have a PMD to worry about? No idea there were clones, how would I know? Thanks

Hummer H1, as Robyn suggests, or HMMWV M1152 (Humvee)? They are not the same. The HMMWV will not have a PMD to worry about, and will also have a 24V...

Hi The AM General engines were much better. Blocks were stronger as were the cranks. The heads are much better as well.... The PMD issue was...

Okay. Well, then, why doesn't it push foam out the PS return? This is why I posted the question about further testing and possibilities. IIRC (You'd...

It isn't making sense. Seeing is believing, but I'm not seeing. Air has to come from the pump. If the pump is pushing fluid, everything is under...

Ooooookay. As soon as I came down harder, on my hose clamp at the plastic cap/air valve end of my pressurizer, my leak stopped. A session with a...

Thanks, Robyn and DMax. Made up an 1.5 in clear hose, with cap, valve and clamps. Clamped it onto the filler tube and used a battery-powered tire...

The aluminum (not plastic) cylinder inboard of the HB unit is the reserve accumulator. DO NOT mess with it. It retains full system pressure (until it...

Thanks, Robyn. You're hitting on something tha Lance and I are actually working on. Lance has read some comments on the HB being a problem. He found...

A failing hydrobooster on the brakes can and will cause the PS pump to whine due to pressure fluctuations.. I have seen this.....I had a 94 Burb...

Diesel conversions have been a somewhat popular endeavor for useful older vehicles with engines/parts no longer available. Your truck might be a good...
