My 2001 Ford Tuarus SES shifts gears irregularly and the key doesn't easily turn on the car, I have to jiggle it a little, it putts until it warms up, my battery just died, so I bought a new one.
The next day it started I put it in
reverse, stepped on the gas, then it
died on me. I had it towed home, it
sat two days and started right up,
but died shortly after. When it started
shifting gears irregularly I took it to
the transmission shop and I was told
its not my transmission, it's my
computer. Should I replace the
computer before working on the
alternator. Any suggestions to any
parts of my despair would be greatly
It sounds like you have multiple things going on with this car. Gears shifting irregularly could be a bad Vehicle Speed Sensor (VSS), failure of the Manual Lever Position (MLP) sensor. Then again it might be a torque converter or simply low fluid in the trans. I'll assume since you had it to a shop those would have been checked and that they recognized it was a bad sensor/computer. You can reset the computer by disconnecting the battery for 30 mins (although you might want to scan those trouble codes first) and see if it affects performance. If you can get it up to an auto parts store (Autozone, Advance, O'Rielly) they will scan for trouble codes and can also check the alternator and battery for free. When working on any computer or sensors on a car disconnect the battery. A new ECU/ECM computer is around $250 to 300 for the part. It's not difficult to change, it's located under the cowl. I do believe however it has to be programmed as they are parts specific and encoded to their vehicle. That can be done by a tech with a Tech 2 Scanner, or by a qualified shop or the dealer.
Thanks for the advice KenF, thanks again.
