Hola Jose Luis, linda camioneta.
No soy experto en el tema tengo una Chevy Blazer y lamentablemente estos vehiculos tienen sus gracias y sus detalles.

El sensor VSS lo encuentras en www.rockauto.com tendria que ser facil de cambiar pero de todas maneras con un multimetro o tester verificar si llega voltaje y / o señal como asi el estado del cable y harnes del sensor (cable partido cortado etc etc).

Sobre el indicador de aceite, tambien verificar cables, harnes, sensor precion. Es extraño que falle el instrumento medidor en el tablero puede pasar , recuerda que el calor del motor a algunos cables los va friendo de apoco.

Sobre la caja automatica no me pronuncio (que modelo es ?)

Transmission Electrical Problem

by CaddyTech [OP] » Jul 08 2012, 12:29am
I'm new to this forum and hope that someone can help. 2005 Silverado 1500 5.3L 4x4 4L60E transmission. Trans will not shift out of first gear, brake and ABS dash lights on. Check perameters with scanner, no codes, VSS at 3mph all the time, spedo not working, at 0mph all the time.
Trans tailshaft housing was replaced because of oil leak, vss wire pinched on install, and has been repaired. Pinched wire was checked in harness for any problems. Three VSS sensors on trans were replaced. These repairs were not done by me, I ran the scanner and checked all fuses. Seems like no power or signal to and from VSS and spedo. What I need to know is which wires to check at PCM, pin # color and pin voltages in order to determine if PCM is the problem? Any thing else that would cause these failures? I am open to sugestions in order to fix this.

Thanks.

OK The problem is fixed. There are three VSS sensors on the transfer case, they are in a straight line from left to right. The one causing the problem was the center one, and the sensor was good. The wiring to the sensors is not a straight run to the PCM, there are two connectors, one low to the sensor wiring and one up top to the PCM, it is a two nwire connector. SilverSurfer the wire colors that you gave me did not match the truck wiring nor did the wiring diagram I have, both were different . the VSS wiring was a GRN/BLK and a PPL/Blk. ann OHM check of the wiring from the VSS plugs to the PCM showed 0 OHMs. The problem was in the lower connector. I cut out the connector and soldered the wires and the problem is gone, everything back to normal.

I want to thank you for your and everyone else that replied.
