Gauge help

I need some opinions here, and would appreciate any help. I installed gauges last week ( boost, pyro, and trans temp) on my 02 7.3 I went with Glow Shift (I know, cheap) because I already have the Torque App and didn't want to spend much money, just want more convent readings. When I went to install them I couldn't remember exactly where to put the trans temp probe, I remembered, or the directions said something about a test port. So I looked around, didn't see one, and didn't have internet available, so I called the Ford dealer. They told me that there is no such port on a 4R100. So, with that I dropped the pan, drilled, cleaned, and installed the proper fittings placing the probe fairly close to the top of the pan. Today I had my Torque app going and saw there was quite a difference between that and the gauge ( gauge read about 110- 120 and Torque was saying 150- 160). I decided to look up installation and found the high press test port on the drivers side. Should I move the probe to that, or leave it in the pan? Is the oil in the pan that much cooler? Or is the difference because of a cheap gauge? Thanks in advance!

Re: Gauge help

Anybody know where the computer gets it's temp reading? My guess is that It reads the temp of the oil leaving the trans to the cooler? So my aftermarket gauge is reading the oil temp after the oil has been to the cooler and back, waiting to be pumped back through the trans.

Re: Gauge help

Test port is on driver side.. It's near the harness that plugs into the trans iirc.

on my 4r75 the temp sensor looked like a resistor in the internal wire harness and nothing like a traditional sensor

Re: Gauge help

The PCM reading for trans temp will always be higher than anywhere you put that sensor on the transmission (test port, pan, etc.). The reason for this is because the PCM gets it's reading from the solenoid body, which is hotter than anywhere you can install your sensor.

Re: Gauge help

Thanks guys! I think I'm just going to leave it in the pan. The test port should read the same anyway because I guess the oil only goes through the pump before going past the test port.

Re: Gauge help

If you add more guages hit up dieselmanor..
great install sheets...good prices too.

that tranny location is on there for sure.
ir will read higher at the test plug then the fluid res.

it is like having the egt in the down pipe..it reads temps but is a bit lower then the common locatiin.
you have to do a little math or just know the limits.

but if you aadd fuel pressure etc they will have the install sheets.
