Title: Sensors,relays, or fuses for tranny
Post by: Oh on 31 March 2011, 02:56:40

So i'm wondering if there's any sensors relays or fuses for the transmission on a 2001 Catera Sport outside of the tranny. I replaced the tranny on mine since the sport light kept coming on and it was giving me a code for a sensor inside of it. The sensor seemed to be priced at 2-400 depending on where i saw it and a refurbished tranny was 450. Long story short I replaced it and the light keeps coming on.

I've read about a possible bad contact on the fuses under the steering wheel. If so how can I make a good contact? I was thinking of just putting some tape over the fuses and making sure that it's snug but i've been procrastinating.

Any advice is appreciated.

this kind of fault  believe is often  caused by the selector switch?
remedy is to take it apart and clean the contacts inside as it gets full of crud

BTW could a dirty selector switch cause rough shifting. By rough I mean the car occasionally lurches forward when driving and the tranny shifts gears.

I presume you have the same Transmission Control Units as us Brits, in which case, the switch is a simple switch circuit to ECU, and the light is also a simple circuit. No complications there - the ECU monitors what the switch is doing and decides whether or not to turn the light on (and go to sports mode).

I think I'd be putting a meter around the switch (or disconnecting it, to prove) initially

So is it possible to check it with a multimeter through the connector by the airbox? What is it that I'm looking for? 4ohms is what I saw. Is that while the car is in park? Reverse? Neutral? Drive? I'm assuming it should be on.

I read that a dirty selector switch can cause flickering on the lights next to the shifter. I noticed some flickering briefly once a few months back but I've had no flickering since.

I also saw a picture of a solenoid from what seemed to be under the cover for the shifter. What's the purpose of the solenoid and could it have any issues that would cause the sport light/limp mode coming on.

So I got under the car and had no room to maneuver around to remove the switch, It's the 3.0 motor and I had room to get 1-2 fingers in between the part and the body. The outside looked grimy. Is there any correlation between the outside grime and inside?
