RE: RPM Surge??
it means a the sensor in the tranny has gone bad... take it to a tranny shop and have them swap it out and do a servicing on it. there is another sensor in there that also goes bad, i'd have them swap that one out while they are in there. I had a tranny problem that related to that sensor, never thru a code and it turned out to be one of the 2 sensors inthe tranny. fixed it and never had a problem again.
