I recently changed trans fluid and filters in my Allison 3000MH.
The controller won't talk to me. When I try to check the oil level, all it says is "ol 70" (oil not hot enough). Even after a 3 hour drive from Tucson to Yuma. Even a day later, with the engine off, it displays "oL 70". It did give me an "oL 50" once, which was correct at the time, but hasn't done that again. There are no error codes, but who knows if that's working either.
I'm gonna be honest and tell you I don't know if this feature ever worked before I changed the oil. I didn't thoroughly read the manual and was only checking the oil level with the dip stick.
The trans runs smoooooth.
Any one have a suggestion on how to wake 'er up before I call Allison.
