How Do I fix this

Transmission Oil Temp Sensor Out of Range. How/where do I find this to replace/fix it?

wow, thats one i havent seen yet. call autozone and check if they have it (or pepboys or advance auto, whoever you might have nearby). my chiltons does not mention a temp sensor at all but i will inspect closer and repost soon. good luck, maybe someone can fill in the holes i left.

I looked on Ford Parts Network and couldn't come up with anything on the '95 ATX tranny for that sensor. The only tranny oil temp sensor I could find was for the Aod-e & Aode-w/4R70W. shrug

I would suggest emailing Torrie to see what he can come up with. mailto:[email protected][email protected]</a>

Edit: FYI

Quoting SHOoo from an old post:

"The '94-'95s use an SHO-specific AX4S (although the oil pan and valve body covers for all '93-'95s still say AXOD)."

Looking through the schematics, it appears that there is a signal from the transmission to the PCM called TOT (Transmission Oil Temp). Must be from a sensor inside the tranny.

Of course, it would be helpful if the exact code was posted.

Did you run the codes while the car was cold? It does have to be up to operating temps, and I don't know if the trans fluid gets up to temp just sitting in the driveway idling either.

Good luck!

To prevent the replacement of good components, be aware that the following non-EEC areas may at fault:

Engine/transmission fluid levels
Engine/transmission operating temperature
Ambient temperature

This Pinpoint Test is intended to diagnose only the following:

TFT sensor

Harness circuits: TFT and SIG RTN

Powertrain Control Module (PCM)

Description

The Transmission Fluid Temperature (TFT) sensor is a thermistor that changes resistance in response to temperature. The TFT sensor resistance decreases as the surrounding fluid temperature increases. The resistance variation is converted into a voltage signal and sent to the PCM to give an indication of the transmission fluid temperature.


On the Transmission Vehicle harness connector, between pins 46 (grey /red) and pin 49 (green/black) and with the tranny fluid temp at...

194F 0.599V 2.750 ohms
158F 1.025V 5.260 ohms
104F 2.149V 16.043 ohms
59F 3.318V 46.883 ohms
32F 3.882V 96.255 ohms

the exact code is 636 TOT sensor out of range.

I checked the codes multiple times... i cleared the codes and did it again, and i still get 636. So any more help would be greatly appreciated.

The TOT (Transmission Oil Temperature) sensor is located deep inside the valve body of the tranny and does exactly what its title implies -- monitors the ATF temperature to regulate EPC pressure and TCC lockup. A really good tranny shop can probably get to it with the tranny still in the car, but expect to pay 5-6 hours labor + the cost of a fluid flush. I would definitely classify this as a non-DIY repair.

You might want to double-check the D-shaped 9-pin tranny harness connector on top of the tranny (just about straight below your throttle body) to make sure that it's on there securely. You might even want to disconnect it to check for corrosion, etc.

If it's not causing any driveability problems, you might just want to let it go until your tranny starts acting up. Until the temperature outside is above 50F, you might want to drive the car very gently when cold, or let it warm up first.

Can you give me a good description of where this D connector 9 pin thing is??? Im SHO A.D.D. So I need a little explination

That was one of several codes I got when the ATX crapped out on my SLO
