The "Check
trans" switch, when flipped the opposite direction of what it was,
caused the "check trans" light to flash the code: Three quick flashes,
short pause, two more flashes, long pause, repeat. So, first digit 3,
second 2 = code 32. Having read OBD diagnostic codes off of cars for
years (many early systems would flash the "check engine" light in the
same manner to show you the codes) this was second nature to me.

So, I called Mr. Oliver's and Paul gave me a name & phone number, and
that person found an Allison dealer close to me and also looked up the
code info.

As for the "J" solenoid, apparently it regulates shifting. This makes
sense given that the light only comes on after shifting. ~$200 + 4-5
hours labor to replace I'm told. I'll find out for sure in the
morning, I suppose.

Ryan I reposted your informative post under a new thread because it
holds good info. The thread subject name and "proper ID of bus" will
help others find the info.

I think it a good idea to remind the Allison Tec that the bus 1)has a
batterybank 2)bank gets depleated during long storage 3)a very high
amp alt. If the J solenoid is shifting properly, why change it. The
code may be generated by some volt, wire, or connection problem that
wont get replaced with the new internal part. The early warning light
is proving to be a wolfcry. Dependent on; amps, ohms, volts, and all
that 'lectric bull, the computer warning lights fail to warn of a
problem with the warning.

I had an Allison tranny shop do my first oil change filter service
because I wanted a pro to have a look at old oil character and filter
deposits and run the bus down the road. That invoice was around
500.00
