Scangauge II question

[frnu]

Hello. I have a 2003 W22 8.1L Vortec with Allison 5speed 1000 Transmission.
I purchased a Scangauge II and programed an X-gauge to monitor the transmission fluid temperature. The device works with the VPW protocol.
As per GM specs, I entered the following parameters:
TXD: 6C10F122194001
RXF: 046205190640
RXD: 3008
MTH: 00090005FFD8
Name: TFT
After entering this parameter, the TFT is displayed on the scanner screen, however, the temperature is reading just 32 degrees Fahrenheit. Outside temp is 78 degrees. The coach was sitting for 2 days now.
What am I doing wrong?
Any help is appreciated.

Probably nothing, drive the unit and bring temps to normal range,

Suggest you PM to Oemy for help because he is an expert about programming the SG II.
FWIW, I think you are correct that for TFT you need to use the “X gage “ function, but all it takes is on digit off during the tedious process to get a bad result.

Scangauge customer service is also pretty helpful with things like this, sounds like you might be reading the wrong PID or there's a math error somewhere.

I responded to a PM from the OP.

But, i thought I would post the fix for the rest you.
The TXD should be 6C18 not 6C10

Also, the temps at starup will be somewhere close to ambient temp.

Just out of curiosity, is this information coming from a separate plug, or is this coming from the OBDII connector? I don't have a Scangauge, but was curious where this info shows up?

Scangauge connects to the OBD plug - either the normal "car shape" or if you have a DP on a heavy duty frame, the round diagnostic connector.

Older coaches like mine have the 6 pin round connector, newer coaches have a black 9 pin, and the newest coaches have a green 9 pin. All have the same basic functionality, but different protocols on them.

OK. Since the trans control module was a separate module, I wasn't sure if the engine ECM was passing that information through or if there was a separate connector for the trans control module.

On my 2003 with the 5 speed trans (factory issue) all I had to do was plug the gauge in and it read out the trans temp. Not so on my 2009 with a 6 speed transmission.

We have never found a solution to the 6 speed for the SG2.

[Dsrtrider]

It does say in the owners manual for a coach with a 6 speed and a certain cluster number it does have trans temp readout? Has anyone ever seen one like this? I just wound up installing a max tow trans temp guage.

If you have it handy, could you post the code for the Scanguage II transmission temp readout for a 2015 Ford E450?

Many thanks in advance!
