  1. Had a similar problem. 2001 R model E -7 460. Speedometer stopped working, engine power loss, shut down warning. Turned out it was the plug on the ecm behind the steel panel near the passengers feet. I had just moved everything to clean the a/c- heater core. I just cleaned the connections and all was good.

    460 operating range?

    My 01RD 460/ 8 spd LL is 1200 - 1800. 2100 max. It likes to be short shifted.
