Scan Guage- Transmission Temp?

[TimLoon]

I have a 2004 Allegro on Workhorse with Scan Gauge I have read the Scan Gauge drections and cannot figure out how to read transmission temp from the Allison. What am I missing? Thanks for any insight you can give. Tim

Tim, Although I don't have the programming parameters for a value called TFT (transmission fluid temperature) at hand, the codes need to be input into the gauge and saved.

Once loaded all you need to do is toggle to the parameter and observe the results. Our resident Scan Gauge programmer is Oemy and he might have the procedure and the strings that you need to enter right at hand.

Thanks Driver for the input. I will go back to the manual and try to work my way through this. Transmission temperatire and mpg is the main reason I bought the scan gauge unit.

Hey Tim, yes Driver is right. I had a scan gauge on the Coachmen Mirada that I had prior to the Expedition. You have to go through the manual and find the code to input to the scan gauge to get it to read out the TFT for the Allison, but it will do it.
Another place is do a search on the internet for scan gauge and go to their website, they may have additional instructions.
They now have a scan gauge for Diesels and I will be getting one shortly, loved it.
Happy trails

Still waiting for the ScanGauge folks to figure out how to get temps for the Allison 6-speed.

When I bought mine last year, I was under the impression Ford was the only one that reported TFT. Guess I'll go check the manuals and X-Guage specs again.

Yep, updated GM and Allison X-Gauges are in the PDF. My bad

Welllll .... One parameter you "can" believe in however the other is always best proven via the ol' paper and pencil method. The digital information gives you a warm feeling but it turns cold when you figure it out the old fashion way.

TimLoon,

I also have a 2004 on a Workhorse. I found the code and directions and programmed in the transmission temp. Works great. I will see if I can come up with the info I had.

On closer look, GM Specific : Linear Logic : Home of the ScanGauge this site has the codes needed to get the Allison trans temp on the scan gauge.

Allison 5 SP TFT
TXD 		6C18F1221940(01)
RXF 		046205190640
RXD 		3008
MTH 	        00090005FFD8
NAME 	TFT

As soon as I get done waxing the beast, I will work on the Scan Gauge.

X2 on waiting on the Codes to get the TFT on my 6 speed Allison. These forums are great, of course because of fine members helping others.
