So after my mechanic stuffing me around for 3 months and my car baking in the hot sun. West Coast automatics fixed her 5150$ but she is my pride and joy. Now my reverse sensors stays on it did have a tow ball and harness which I've removed I've checked the plugs in the boot drivers side when I bought her she was missing a sensor but found a new set installed them still not working could it he the buzzer or will that be fine because it stays constantly buzzing when in reverse any advice would be appreciated
That is a normal price. The 5L40e is a hard gearbox to find parts for. The shop would have been waiting ages. Add to that, there is only a few good transmission places left in Perth and SW WA, so wait times to perform work are also long with high demand.
It’s a tough one to find a solution to.
I’d be removing the rear bumper. Remove the sensors and set them up off the bumper. Engage reverse. Does it do it?
Next is to get the module for it and see what’s going on.
You can buy the module NOS still. It’s the same as VE one that’s installed as a kit by dealers. Rear only. This is different to the modules factory fitted so look for the VE kit on eBay.
It’s also possible that there is a faulty sensor. I’ve seen a few VZ sensor harnesses for sale on eBay. Might be worth trying another harness and sensors.
