Sure I'll be wearing my last brand new old school green canvas TTC parka taking my night shift snooze on the back seat. Bus idling in reverse(so the lights go out) and the heat blasting. Not that I ever did that, just sayin........

This is all the parts that you can still buy from Allison for a VH transmission. Not much to work with but we'll manage.

I just have to say, I wish you guys the best of luck restoring 8058! Boy, she was not in good shape coming back from HCRR.

Ah, how I miss the sound of the 6V71N/VH-9 powertrain! ^_^

Malvern Division did an excellent job in keeping this bus active.

Today I worked on the front end(or rear if you follow the manual) First I assembled, installed and tested the Hydraulic and Direct clutches then built up the converter (we used to call it the turbine). I built piles of turbines and clutches back in the day for the divisions as it could be changed as an assembly in the bus. The test fixture for the clutches was found in a pile of junk in old Davenport Garage. Took a bit of scrounging but I was pretty sure it was there.. here's a video of the clutch test

These are really cool videos. The parts of the bus that are rarely seen, other than by those who work on them.

What sort of grade steel is used in the VH transmission? S45C? Is it the same grade throughout?

What? The gears themselves? Dunno. The casing is all aluminum.

A nice coat of Tremclad Aluminum

Painting it brought out a lot of detail including previous welding repairs to the case.  Stampings indicate the turbine originally came from bus 7769 and the case came from 3567. It has a casting date of 2 August 1968. The complete transmission was later numbered TR1568 but we could find no record of it.

What type of fluid does this tranny take? A proprietary diesel fluid or some along the lines of Dexron or Mercon?

Dexron III for the old stuff is fine, although the TTC has standardized to Castrol TranSynd some years ago.

I am assuming it must be in bulk to whatever supplier it is. I wonder if Mobil Delvac would run just fine if something were to happen to Castrol.
