Allison Transmission WTEC II Problem

#1
Have an RV with an Allison WTEC II. Cannot display any diagnostics. Only Cats Eyes will display. Metered the
input power and there is power coming in. I spoke to a friend and he stated that the components I.E.
capacitors resistors and diodes will malfunction and should be replace. Again. C1 etc. Any input related to this
situation would be greatly appreciated.

Thank You.

Re: Allison Transmission WTEC II Problem

Cat eyes is normally indicative of a communication problem between the push button assembly and the electronics of the selector. Is your push button assembly remote from the ECU or integral?
