PID for trans gear selection L5P

[Metal.Dave]

Wanting to put in a UltraGuage, and one important PID I need to see is trans gear selection.

From what I know, the Ultragauge does not have that capability without some kind of coding/ programing. 

 

Has anyone successfully done it, and if yes can you share the process?

Sorry, I don't know anything about UltraGauge.  I do have a Scangauge II and programmed some codes.  These work for my 2024 2500HD gasser 10-speed.  They might be the same for your 2021 Duramax 10-speed.  (Ooof, or did GM change everything in 2024???)  I looked briefly at UltraGauge and the parameters seem different, but maybe translatable (?).

 

TXD = 33F1227053

RXF = C46205703653

RXD = 3008

MTH = 100010000

NAME = GER (or I used TGR)

 

I got codes from Scangauge support (email) and they were very responsive and helpful.  If these codes aren't right for your truck, I would think Scangauge support could give you codes . . . for a Scangauge.  You might check with UltraGauge support to see if they can help.

Thanks!!! I will reach out to ultraguage and see what they say.

Also did ScanGauge II gear indicator on our 2021 6 speed. Very responsive company.
