Well his knowledge of the event began with an oil pressure warning light so the pressure went below 15psi. That probably was caused by the oil pickup sucking air...

Well if no bearing or journal damage was done form the pressure loss, any metal from the governor or anywhere else for that matter will probably wind up in the pan...

It is the oil supply line. It taps a pressurized oil supply gallery that probably also feeds the camshaft. The governor oil returns thru the front into the timing case. The only plumbing connection the governor has to the fuel system is that it contains the Fuel lift pump. Remember the...

Exactly!

Oil line block to governor or oil line block to compressor, both On drivers side, both would dump a lot of oil quickly. The governor line is right between the block and the governor. The oil line block to governor has been a repeated LMTV failure point possibly caused by excessive vibration...

Yea, there are lots of ways to fry this fish...

The only people I can think of with that capability In the NW are the folks at Grigsby Trucking down near Bend OR... I am thinking that 5solids is probably more a hardware fault. Something has to turn those 5 lights on And I am thinking the software when initially powered on runs some form of...

Short for water buffalo?

You wont see any drop on the primary or secondary gauges. The compressor feeds the dryer, the dryer feeds the wet tank, the wet tank feeds the primary and secondary tanks thru check valves. The wet tank also feeds CTIS thru the protection valve. The only way you will see a pressure drop on...

Yea for regular CTIS applying air from an alternate source is the way to go to find leaks instead of waiting on the processor to Briefly pressurize it. Another way is to disconnect the CTIS connector and jumper the 28V pin to the control solenoid and briefly jumper the 28V to the inflate...

a badly sulfated battery will have good specific gravity and cell resistance. It just doesn't have very much plate actually exposed to the electrolyte So falls on its nose when a load is placed upon it... Glad you found the trans issue...

First off, Are you sure it is not filling? the tires consume a huge ammount of air. Once you energize the control solenoid(closes its valve) and energize the supply solenoid(opens that valve) to let in air, the wet tank on mine drains to the protection valve cutoff point(85 PSI) in about 3...

Correct! The Allison has its own RPM sensor down on the lower right front of the transmission housing...

Yes, the output speed sensor is used by the TCM before it is output to the speedometer. In the section for troubleshooting 25 series faults in the Alison troubleshooting manual gives a few other reasons for the 25-11 code, like an inaccurate turbine speed sensor output...

Well the good thing about codes is it will store new current ones the next time you try and drive it. Go try it, read the new codes after it fails and write them down...

Any other codes besides 25-11? It can store 5 codes I think?

There is an IOS app called “sonic tools“ that might allow you to identify a frequency at which your vibration is occurring, which might help you locate the source...

You can also get the 3 wire plug-in can style solid state flashers that should also work.

Do you have an IOS device(iphone, ipad)? There is an app called sonic tools. It uses the accelerometers in the device and can display the sensor information from all 3 sensor axis, in a Frequency spectrum like a spectrum analyzer. If you can measure the frequency and Know at what speed and...

Yep, not layed out to make a large drawing. The page mapping actually works best when they are layed out in a long line. I use mine on an ipad pro as I can scroll thru the pages easilly while tracing a circuit. when tracing out a circuit, I use a notepad. When the circuit leaves a page, I...
