Hi all. I'm new here but hoping someone can help. We're stalled right now near Harlingen, Texas. Although we're talking with a tranny person, still can't figure the reason for stalling -- on the highway engine looses speed, goes down to idle, transmission flashes #6. Upon checking code, we get 0L-50 and when we press the two arrows again we get D1- but no code is indicated after the D1- to indicate the problem.
After letting the vehicle sit for 15 to 20 minutes, we are able to drive for approximately 15 miles and the same event occurs again. We've contacted Alison transmission experts but they are uanble to diagnose the problem without a code.
Upon stopping the vehicle, the engine will not rev up and the vehicle will not go forward in gear.
ANY help would be appreciated! Thanks. Lissa

Thank you thank you Jim. Please tell me what a turbine speed sensor is. We are literally on the side of the road! Can you be contacted personally now by phone?

Hello & Welcome Lissa:

Sorry to hear about your predicament, the only thing I would recommend is to have the coach towed to an Allison or Cummins repair facility. I hope you have Good Sam or Coach Net for the tow. It is difficult to diagnosis a problem such as yours without the diagnostic codes. Even if we could, finding the proper parts will be difficult. We wish you the best of luck on getting the coach repaired. I am sorry I can not be of more assistance.

You may also want to Post this on the Allison Transmission and Cummins in the Drive Train Garage area of this forum.

do you know if your unit has the electronic eng. or does it have the mechanicle eng. if it has the mech. eng could possible be a issue with the king control throttle system. if so they were bought out by a company called cruise king. they might be of some help to you

The OL 50 code states that the engine rpm is too low. Since you have no error codes it may be the problem is with the engine as racer_ss says. You probably have the same engine as I do which is the Cummins C, pre ISC. Mine is currently at the Allison dealer because I do have some failed sensors and these did come up with error codes.

I hope they find a good shop. I think its engine also. There should be plenty of service in Harlingen TX.

I was told WRV never made a non-electronic engine coach, which I believe is true. Most stuff was electronic by late 90z

Actually, the very first were mechanical engines. I remember gentleman telling me he had gotten, in an Alpine, a "non electronic" engine because his relative warned him, "them new fangled electronic gizmos will never work." For what it is worth.
