You have at least the about 1/3 of the mounting hardware, the missing pieces are the truck sides of the mounts and the rubber isolators/special washers

Here was a quick search of a few sold shelters, the first two are NOS, the bracket is likely OEM as the A/C units were stupid heavy. https://www.govplanet.com/jsp/s/search.ips?k=S-788&sm=1&mf=1 And another NOS...

Pictures would help, I see them going from $600 or so on up, I bought a real nice one that was delivered all the way from Houston for $1000 and a NOS one for around $1750. I did watch one in disbelief go for over 5K, there was nothing special about it, only that least two folks wanted it...

The first thing you need to do is pull the TCM box and open it up, water intrusion is very common, sometimes you can dry them out, sometimes it is too late. Yes there are a couple different styles of TCM boxes and TCMs themselves, all TCMs will interchange, some have different shift points...

Yes, that is C and D on the transmission connector not the J1 TCM, you would need a special cable (as it states) because it is very difficult to access the transmission connector to measure it with meter leads. Notice it does not reference J1 in the procedure, only the special test cable, that...

Great Tip!! The first thing I do when doing any serious work on any HMMWV is to pull the tires, makes everything easier, a real plus is to have it on a lift at the same time. I drop a couple 4x4 blocks at the base of the lift towers and when the lift is put all the way down the geared hubs just...

You may want to think of fabricating these in bulk, there are allot of ambulances out there with no steps, seems the doors are not too difficult but the steps are.

I will again try to explain, thes pictures in your post are of the J1 connector at the TCM, the C and D pins on this connector have nothing to do with the PCS circuit, however the lower case k and g are part of the PCS circuit, you reported seeing 4.8 ohms there which would be in line with a...

Again the C and D pins associated with the PCS circuit are at the transmission connector not the J1 TCM connector You are looking at the wrong connector for the C and D pins, look at the schematic I posted above and it is simple to see. You will not get continuity at the C and D pins at the...

The cam is driven by a chain off of the crank, the IP is gear driven off of the cam. So standing in front of the engine the crank and cam turn clockwise and the IP turns counter clockwise.

Welcome to the SS forums!!

If as you stated earlier you are seeing 4.8 ohms at the J1 TCM connector lower case k and g then the PCS coil is probably OK. If you do see 4.8 ohms at k and g then it is time to pull the TCM, box and all and put it on the bench and open it up and check for moisture. If everything is dry then...

The C and D you see on the schematic is for the connector at the trans not at the TCM, the ones you want to look at at the cannon plug (J1) for the TCM is lower case k and g D and C on that connector is used for something else.

It sounds like you have a non functional TSU or a mismatched TSU Here is the link to the sticky where you can see what TSU you need for your PCB https://www.steelsoldiers.com/threads/pcb-eess-smartstart-s3-i-pics-info.164930/ I have never seen a wait light when fully warmed up (other than a...

You said you had 4.8 ohms from k and g was that with the cannon plug removed from the TCM box? If so you likely have the same thing at C and D, Swapping is simple just unbolt the TCM case (4 1/4" nuts) from underneath the body and pull the box.

I smell toast! Sorry!!

Same components as civy transmissions, 4.8 ohms is right on the nose for the 4L80E considering you can have up to .5 ohms loss in your test leads and there is a small amount of loss in the wiring from the solenoid to the TCM plug. It is possible the PCS circuit is bad in that TCM, if you can lay...

Have you gone through the troubleshooting for code 73 in the 4l80e supplemental guide?

The trans light should be on until you start the truck then go off when the engine is started, what codes are you seeing?

I did not even notice how well I nailed the parking spot until looking at the picture. Even though I am considered permanently physically disabled by the state of Texas I rarely use a disabled spot, there are too many folks out there that are much more disabled than I am, when the wife catches...
