I asked ford dealer about this and aparently this is called the gem board. To replace it is 400.00 + ford must reprogram computer to accept new. By some merical if you found one in a salvage yard it has to be same year, model, make, and configuration of code #s,
Any help from the club would be a great help since shop labor is very very spendy.
where is the trans range sensor?[/b]
According to my service manual, the trs is actually bolted to the transanxle. It is removed by,
1, disconnect battery ground cable
2. Place manual control lever in Neutral
3. Remove engine air cleaner and outlet tube
4. Disconnect electrical connector from trs
5. Remove manual control lever from transaxle
6. Remove two tr sensor retaining bolts
7. Remove tr sensor
Of course it recommends a special alignment tool to replace it ( t92p-70010-ah tr sensor alignment tool)
Install:
1. make sure manual control lever is in neutral position
2. Install tr sensor loosely install retaining bolts
3. Align tr sensor using alignment tool
4. tighten tr sensor retaining bolts to 7-9lb-ft. or 9-12N-m and remove alignment tool
5. connect tr sensor electrical connector
6. Install transaxle manual control lever. tighten to 8-11 lb-ft or 11-16N-m
7. Install air cleaner outlet tube and engine air cleaner
8. Connect batteryground cable
9. check for proper operation, engage parking brake( for safety) vehicle should ONLY start in park or neutral
That is what I could find, my service manual is from 1996 but I believe it is the same for your vehicle. Just remember any info posted on
this site is use at own risk. Here is another post about the trs issue. I hope I helped somewhat, it would be a good idea to get the obdII scan to see if its throwing any codes. Any autoparts store will check it for free if you can get it there. It would be bad to spend the money
and replace that if thats not really the issue, money being tight as it is these days!! Good Luck!! Ill keep following the thread I am interested
in the outcome! :salute:

I may have to re-think buying genuine Ford parts. Three days ago, my 2002 Taurus lit up the Check Engine Light and the Transaxle Light. I had the OBD II scanned and it showed a P0705 code - defective Transmission Range Sensor. I pulled out my Ford Wiring Diagrams manual and checked out the switch. Sure enough, one section of the switch which was connected to the Powertrain Control Unit was completely open. I bought a Ford replacement, installed it and no more warning lights.
Being an engineer, I took the switch apart to see how it failed. The problem was a printed circuit board within the switch with extremely narrow copper runs. They were so narrow that they simply broke apart, thereby disrupting the circuit.
My only hope is that Ford has improved the design. Otherwise, I wonder if I would have been better off with an Echlin replacement part.
