Yea Christians unit is cool, but for the ammount I will use it, 3 switches, a relay and a pressure gauge makes more sense to me... it is also nice to manually pressurize the system to look for leaks...

I would suspect something is shorted in the turn signal switch wiring…

I always found that style of troubleshooting a little arrogant. Oh there can be nothing wrong with our controller.., if the wiring is good and 5v source power is making it to the pressure sensor and it doesnt work it must be a bad sensor, instead of actually probing the line to see what the...

You would have to use a short pigtail hose between the PCU pressure port and the gauge sender. The way they oriented the port the bottom cover partly surrounds the sensor and The 0-100 psi piezeo sensors just barely fit… you could easily fit a mechanical gauge sensor line there. Isspro is a...

I think you may be overthinking this a little. RPM has little to do with this, other than in determining torque output at the engine. To perform a specific task, say pulling a 40,000# truck up a 30 deg slope, yes by removing the 2:1 at the hubs, you are doubling the torque applied to all the...

Ok, first off, you don’t have a VIM on a 2004. You have a trans keypad/shifter in the drivers dash and a trans controller under the passenger dash(where the vim was located on the A0). The A1 only feeds 24V to the transmission for both battery power and IGN. CB43 should provide the batt power...

The third planetary carrier turns the hollow transmission output shaft. The c6 clutch all the way in the back brakes the third sun to develop an additional ratio. I spent a day home sick once working it all out and had all the interactions in my head, but have since brain dumped that info:)...

If you drop to two batteries, you can get rid of it entirely. The main purpose of that relay and the LBCD that controls it, was to disconnect a faulty battery from the alternator when it fails, to keep it from damaging the alternator and allowing you to continue the mission. if you properly...

So put them on, if you don’t like them you can always put the spiders back on… unless you are contemplating a LOT of weight, I do not think you will be disappointed

You cannot apply twice the torque to anything, because you do not have it available. With 2:1 hubs, if you are VERY heavily loaded in a max traction situation and against an obstacle/slope you cannot surmount you will apply all your available torque until you reach TC stall. All the...

Took me a bit to get my brain around your table, and your gear ratios are a bit off. 1- the transfer is not shiftable. It applies a fixed 1.2:1 to all the input ratios using 3 large gears. They took a 3060 transmission with its 6 speeds(our 2-7) + R and hung the 1.2:1 off the back end. In...

The battery disconnect light is controlled by the state of the disconnect relay in the box to the rear of the battery box… since all the 12 and 24v power passes thru it, if you are operating normally, it is obviouslay not disconnected, but that is where the idiot light is controlled from…

Basically you disconnect the axle vent line and screw in a low pressure gauge. Then pressurize CTIS(you can do this with jumpers at the controller connector, or disconnect the outlet line at the PCU And connect an air pressure regulator set to tire pressure to pressurize the system. If you dont...

Perhaps, that is a heavy wheel assembly... I will be welding mine to the upper channel that I am converting into my floor structure. It will partially support my wheel, but I will also be adding additional steel plates diagonally upward thru my hab that tie the wheel weight back into the upper...

The 2 square ones are not used, the white one is also not used, the two round ones are your turn signal flasher(larger 3 pin) and what looks like the PCU pressure sensor(small,3 pin). there is probably a round 5 pin kicking around in there also. The 3 airlines and that pressure sensor line...

Yea a pic would help. They made this truck in several configurations, so there will be unused plugs under the passenger dash(chem detect, radio power, 1079 box harness ect) Being a 96 it would have, from left to right, a VIM, a turn signal flasher and a solenoid valve for the fan control...

Very nice!

If the wet tank pressure sw is operating properly, closed above ~117, open below ~89, I would not call the pressure sensor bad untill I confirmed its input and output. The pressure sensor gets ground and 5V input from the controller on 2 of its wires(pins C and B respectively). and outputs a...

What year is the truck(always state the year of your truck)? Is your power panel black, or is it a green circuit board? Pre ~98 it could be a vehicle Interface Module(VIM). Post 98 it is probably the trans control module. Pre 98 they put the wtec 2 TCU in with the trans control keypad, and...

CTIS vents? The only CTIS vents I am aware of are the horns on the dump valves themselves. The dump for the front axle is on the right side of the transmission. The dump valve for the rear axles are located on a crossmember above the axle near the center of the chassis… on mine it is on...
