Hi there.i can help you with this..i'd like to know the model of your transmission so i can confirm the code.if you feel its for the output speed sensor then check the sensor for resistance and let me know what you get.. the sensor is closest to your output yoke at the tail shaft of your transmission..
Thanks, XXXXX XXXXX try that. But, first, I need to know what the speed sensor l looks like. Is it something I can buy off-the shelf and replace myself? Or is it something I have to take to Allison to repair?
I'll get back to you to confirm, but I believe it is model M3080 6 speed connected to a Cummins 8.3.
its the closest sensor to the output yoke
easy to spot
ill be away till sundry...you can choose to go with another
or ill talk to you sundry//thanks
I went to the RV this AM and crawled underneath with my ohmeter and to look at the Transmission.
It is a M3060. There is a sensor at the end of the transmission opposite from and farthest away from the engine. There is also a sensor of some sort on the lower left side (facing toward the front of the RV). I assume the the output speed sensor is the one farthest from the engine. I tried to check the unit but there were no exposed wires and I didn't want to dismantle anything until I know what I'm dealing with.
It looks like a simple seal and locknut arrangement that should be easy enough to dismantle and replace. But, I don't want to dismantle until I have some idea of where/how to get a new unit.
