2004 Ford 4R100 transmission

The OP has an 04 class A V-10. It would be much easier and cheaper to get an OBDII dongle and a good smart phone app. I run Dash Command and can read any parameter I would like. app was $10, 04 Ford parameter another $10 and the OBDII dongle was $17. so for $37 I have a very in depth program to read any sensor I want. I mainly watch trans temp and engine temp.

If your 04 is a Super Duty diesel, it is probably a 5R110, not a 4R100. I think they went to the 5R when the 6.0 debuted.

I used a wifi obd2 dongle and dash command app on my phone with the PID for transmission temps...should work for your truck and no tapping lines.

Just an option.

Thanks!

Sender port is in the driver side near the shift lever. That's where I installed my sender

Chopperbob Where is the plug located? I did not see it

Thanks

I installed a Scan Guage & plugged it into the OBD II port primarily to monitor tranny temp..

There's a plug on the drivers side for a sending unit.

I did some more research and found the answer the oil flows from the front outlet to the cooler to the rear of the transmission.
