With that amount of water out of the main drain, and it never being run in that condition, you will probably be fine as it want straight to the sump and pushed oil up. I doubt it ever came in any significant contact with the friction material. The main housing fills before oil gets high enough...

If it filled with significant water, the transmission dipstick should indicate this(will show it full of fluid well above the dipstick marks. Most anything on the truck can tolerate some water in it for a bit EXCEPT THE TRANSMISSION. The friction material on the clutch discs is bonded to with...

Here is the vent installed, under my dipstick tube. It is lower than the top of the bell housing…

no, the bell housing vent is a hose up alongside the arch that supports the cab latch. There is a small round metal cap breather/vent screwed into the top of the main transmission case, about 18" aft of the bellhousing/cab arch. It is only marginally higher than the top of the upper chassis...

There is a little air cap/vent on top of the trans housing. If water got that high, the trans probably has water in it. Do not roll over the engine or trans until you confirm no water in their oil. Water kills the clutch plates. First check the dipsticks for excessive level, then drain the...

Yea sounds like a restriction, and perhaps a leaking wheel valve. Pressure should equalize fairly quickly each time it cycles, if it is not, ctis will fault, same if it is too uneven at the start of a cycle, pressure equalizing causes unstable pressure and the unit faults, so it takes a few...

Only one gasket sees water/coolant, the cooler to block gasket, the other gasket only sees oil filter housing side to cooler outer face…

Yep, that's how you do it. Old school but fairly common way of getting engine RPM off a diesel... I just don't think the A0 alt is capable of it. They have that terminal configured for AC on the A1 alt and the LBCD monitors alt RPM using it to make some of its decisions...

On the A0, that second terminal on the reg is not labeled AC, it is labeled F- and is intended to monitor the duty cycle/pulse width of the pulses used to excite the field (How hard the alt is working). Not sure what freq it is being pulsed at by the regulator, but I suspect it is not...

Not an automotive tach, those are typically sensing ignition and are only looking for 1/2 pulse per revolution per cylinder, I E: a V8 has 4 pulses per revolution. you need a flywheel/magnetic pickup tach that can sense the 133 pulses per revolution created by the sensor monitoring the passage...

Thats good, but the ABS modulation valves are inline and could be effecting final output even if ABS is not activated. The only way to confirm this is with T fittings at the cans and pressure transducers looking at the final pressure actually reaching the cans.

There is actually 2 RPM sensors, one lower right belongs to Allison for transmission control, and one top left just to the rear of the primary fuel filter/primer, to drive an electric tach. a mechanical tach? Cant think of any place to get rotary motion from to drive one. One reason no one...

Providing everything is aligned correctly and delivering to spec. You need some T fittings and pressure gauges/transducers to confirm the pressure end, the rest is mechanical. Shoe free space(.026” center shoe?). wedges have a limited amount of travel and if the mechanical alignment isn’t...

Yea at your weight, your cable was slack and should have been full on and would have been delivering full braking if not blocked. I wonder how much suspension unload and weight shift you get during heavy breaking? Havn't panic stopped one of these heavy yet:) With a working valve, If you get...

Probably not at that weight as it should have been at or near 1:1 output anyway, but i would still skid pad it at the first opportunity just to make sure it behaves OK. I have overdone it before and too much rear brake is definitely no fun when it gets slippery. I mean I like drifting and all...

yep, with the proportioner blocked, you only had front brakes, and the pacbrake… i would definitely test it close to home when it gets slippery out before I deliberately took it too far out into those conditions…

sounds like it was not working right. You can bench test it. Regulated pressure source on the drivers side port, say 80-100PSI, and a pressure gauge on the passenger side port. Lever against the up stop, output pressure should = input pressure, (1:1), just like your pipe fitting. As you...

What truck is this on? the normal load sense valve only has an input(drivers side) and an output(pax side) port. On the A0 they Td the input so it also fed I think, the trailer brake protection valve and the anti compound valve. The output on the passenger side feeds the brake relay valve…

Well ABS does perform the function of the load sense valve by helping to control/prevent lockup on a light rear end. These valves are 1/6 pressure input to output when lever pulled all the way down(empty bed/light rear end) and 1:1 when the suspension is compressed enough to allow the lever to...

Yes.
