Transmission Allison AT542
I have an Allison AT542 transmission in my 92 Itasca.
Would anybody have an electrical schematic?
I need to trouble shoot my backup lights, all my fuses are good. but I'm not sure where the relay and the actual switch on the transmission are located.
Not sure if it could be related, but my cruise control is not working either, there is no power on the brake pressure switch up by the master cylinder.
I have service records of it being repaired just before I bought it, along with a receipt for a new vacuum pump.
