For what it is worth, I removed the APPS and tested it here at work. Apparently, it is a Hall effect sensor. Hall effect switches and sensors rarely fail, so I am told. I plan to do some more research to see who makes the sensor.

 

I talked to a local tech who wrote an article for G.E.A.R.S magazine(american transmission repair assoc.) and he claims oftentimes the APPS signal is clean until it enters the ECM then it gets noisy-then when it gets to the PCM is where the trouble starts.Luckily mine is still working fine after reflash(8k mis.)Those little noise filters sound intriguing.

 

On my truck it happens at about 30-35mph and usually coasting going down hill in town. Maybe I should try the reflash as it happens everyday on the same hill so I have just been putting tranny in neutral and braking more :. I am not at the point where I am going to buy and new APPS from the dealer.

My truck was doing this for the last 6 months. I finally broke down and put the APPS on it and problem solved.

This sounds like a possible safety issue. Has anyone thought about reporting to the National Highway Safety Administration (see their site), known by the acroninm: NHSA, and see if they will force the company to recall the part. Alternatively, there is the possibility of a class action agaisnt the company for putting out a defective product. I believe this to be a safety issue more than a mechanical problem.

 

The Noise Problem is ********.... Isolation of noise didn't help me a bit....neither did a 480.00 APPS....come on guys this is bad info to the Computer....then the computer just keeps on passing bad instructions.

 

I had the reflash done and it worked good for about 3000 miles but now its back just not as bad yet.
At 40-45 the TC locks and unlocks if I'm just trying to hold a steady speed(in town) but if I'm accelerating to highway speed it does fine. Even with the overgrive off it does it only at a lower speed. Befor the reflash it did it at most any speed.
