Howdy, I've got an M1123 Humvee with the 4L80E. Fighting a weird issue where the Transmission basically free wheels in reverse (meaning it feels like it's in neutral) but only after driving for at least 30 minutes or so. The longer I drive and the faster I go the worse the condition gets. A...

Hi Coug, fortunately I don't think the pump is leaking, just a bit noisy and kind of weak. Effectively having the remote reservoir setup is probably already doing the same process you described since the pump must be constantly be getting a supply of fluid from the big container on top of the...

Hello, I keep it in the site glass. I do have some spillage at the top of the reservoir where the rotating vent cap connects to the large bolt. Its a bit annoying but since this is not a pressurized part of the system I know its not contributing to my issues. Also take into account that I off...

Hello all, I noticed recently that my PS was getting noisy especially while off roading as well as becoming hard to turn at full lock or when in a jam on the trail. Upon inspection I noticed that my steering box was leaking out of the cover and possibly near the output shaft. Long story but I...

Hahaha she is actually leak free believe it or not. But yes as I said no big deal. I am sure a little noise comes through when messing with any electrical component. Once again I don't really know much about electrical but you can't learn if you never ask or try.

Yepper. So far so good, paranoid now that my box is cooking GPs but so far these plugs are starting the truck right up without issue. I did a little multimeter test to see if any of my electronics were making the box act funny. I did see very tiny jumps in the voltage on the leads when messing...

Thanks for the advice guys. Pulled injector 2, 3, and 4 (going from front to back on the driver side of the motor) and blew compressed air in through the glowplug hole. Nothing but soot.... So in other words the motor definitely ate the shards. Current glowplugs looked brand new so I have no...

I was having bad cold start issues and even though the GlowPlugs ohmed out as good I decided to take them out and replace with the Wellman plugs.... Needless to say I was shocked. Definitely don't trust your multimeter! Also I should state that I verified my smart start box is functioning as it...

Thanks!!!

Yep, big reservoir, not overfilled but I do wheel my Humvee so it gets some pretty extreme angles. That part is not designed to leak, you are thinking of the vent hose.

Howdy Folks! Just wondering if anyone knows part numbers on the o-rings within the power steering reservoir vent cap. There should be a larger one for where the cal screws into the reservoir and then I think a smaller one for where the rotating vent mechanism is held into the cap via snap...

Another update: Started checking over other suspect electrical components. Thought maybe the cold advance solenoid could be bad. Seems as if the switch is doing its job and supplying 24v when engine is cold according to my multimeter, also clear that the solenoid itself is getting power. I...

Thanks will do.

Yep, all 8 ohmed out at under 7 and all 8 leads are supplying ample power. Not to mention I just changed them all about a week ago thinking the same thing. I am wondering if the cold advance solenoid has something to do with this. White smoke to me definitely indicated its getting good fuel too...
