Hello all. I am new to this forum and have never actually posted for help in a forum before. My issue is that I'm a computer guy - I fix computers, networks, check the security of networks, etc... I own a car though, and have a vested interest in learning to fix what I can.
So enough of the intro, here's my problem:
The car backs up, but any throttle applied will not effect the process. It will back up at an idle speed (sort of). If there is ANYTHING behind the tire (pinecone, foot, etc...) it will not have enough torque/power to push itself over it. This also means I cannot reverse if I am in a hole/puddle/bumpy area.
The check engine light comes on; I went to a garage and had our local mechanic/friend put it up on the "computer". It reported a problem with the quad driver module. I don't know what this is, and neither does any mechanic I've talked to in the area. I read that it controls all kinds of things though, but I don't quite understand it. My idea with my limited understanding is that if the QDM controls the converter clutch (lock-up transmission thing) and the clutch is burned out... that may be why the error is being reported. The blue plug which controls the TCC has been unplugged and the car no longer bucks at 30-45 miles an hour. The check engine light, however, still comes on. I have no idea if this is relevant - but it seems to be related to transmission in some way.
I do make sure the fluid is apt and I JUST changed the filter 2,000 miles ago. This reverse issue has been happening for the last 75,000 miles or so (before I got the car).
Thanks or reading, and any help or suggestions would REALLY be appreciated.
