I am having a speedometer issue. My transmission overdrive (Im assuming an electrical connector) is having a problem, and now my speedometer is having a problem separately.
First I have had an issue of RPM loss, and loss of power going up any tiny climb or grade, I can be in overdrive at 60mph , to 70 mph, my truck loses rpm fast going up hill....I drop from 70 to 60 mph within 10 seconds,.
my engine is rebuilt by a 5 star engine house, my transmission similarly rebuilt by a 5 star transmission house..... this shouldnt be happening. I do have what I think is a bad wiring harness that connects to the outside of the internal transmission electrical harness, the connectors or wires externally seem to short when it rains, and I lose overdrive immediately in the rain . Aside from that , my speedometer began to "slip" at 40-50 mph , it doesnt respond then sometimes it jumps up to the mph of 50, or it slips rapidly down to 40 despite constant speed. Is this speedometer issue the gear sensor? Or is this related to actual transmission slipping? my RPM stays constant when the speedometer slips. These two issues seem separated. I already changed the rear differential speed sensor....I know there is a shaft output sensor, and a gear for the trans...
does anyone know a thing about the transmission electrical harness and overdrive? I cant find a single diagram or part name for the harness plug
