Besides the gauge posted above (which seems very reasonably priced) what are people doing for trans temp monitoring? I would like a smaller and more discreet temp readout if possible.

Is there an easy place to tap into to get trans temp? I've read mixed reports of a sender on the 2000 Excursions. Is it possible to read the temp with an OBDII scanner?

 

I had aftermarket (Napa brand) tranny coolers put in both Excursions as well as in line filters and synthetic tranny fluid. The 00 has 270K miles and the 02 has 300K miles both trannies are original and shift good.


On the other hand the 99 F250 is on it's 3rd tranny at 335K miles.

 

A Scanguage II will read the trans temp through the OBD port.

 

Perfect. I have a couple on the shelf. I'll have to install one.

 

I just added the Scangauge II for this exact reason. While a stand alone gauge would be nice this allows for monitoring of many other items too. It fits perfect in the cubby in the dash as well, can be removed easily and transferred into another vehicle if the need arises.

 

I used to use the ScanGauge II, then (because I have seen one E40D blow up in my Expedition on me) I added a glowshift in the test port on the side. I should expand - per the repair shop if some Ford transmissions die 'young', they reman them and put them back on the line. The Expy I bought was a lease with all paperwork (no trans rebuilds) and the repair shop asked me when I rebuilt it, then told me the one I had was reman (probably at the factory) and they didn't put it back together right, so he was shocked I put 130k+ on it towing and it took that long to come apart.

I read somewhere once that the numbers given to the ScanGauge are 'estimated' temps by the computer - can someone debunk this or is it true?)

When I sold the Expy and upgraded to the Excursion, I put in a new glowshift and now I also have an SCT monitoring the trans temp.

 

That's false. There is a sensor on the solenoid body that reads actual temperature and reports that to the PCM. The Scanguage reads it from there.

 

Once again, Mark comes with the dope information!!

 

My vote is for the Scangauge as well. I have one installed, did have to use double sided tape so it would hold though. Also I constantly monitor IAT's, Water temp, Trans temp and RPM. Trans temp does have to be loaded, but the codes can be pulled from the scangauge website. I think the one below is what is used.

I was thinking that I was charged for 17 qts last time I had the trans/torque converter flushed. I thought it was crazy at the time, but that's what it is.

 

Thanks everyone for the replies - further update on my progress.

Mark in reference to your concern on my post about fluid - I ordered a case of 4 of the 5 quart Motorcraft ATF fluid - so 20 quarts currently on hand - hopefully I am in good shape.

I am having a very difficult time locating the correct threaded fittings for the new radiator. The closest thing I found were brass 3/8" barbed fittings with 3/8" NPT male thread at the hardware store. Seemed to be a near perfect diameter for the female threaded ports in the radiator - but thread style was different.

The radiator is a Murray brand from O'Reilly's and not to pick on the staff at my local store - but they have not been much help. Tried to give me fuel line for the additional 3/8" hose needed and after several tries they brought out labeled transmission hose. They cannot seem to tell me what thread style is in the new radiator I purchased.

Work is getting busy so that is slowing me down on the search if anyone has suggestions for a source of the radiator fittings - it's greatly appreciated.
