Greetings from Southern California !!
Might any of you fine folks know the details of the "high-speed solid-state engine-temperature sensors" used on our DigiPanels ??
I'm contemplating the installation of a proper temperature sensor port on my transmission pan (and probably a drain plug) and would like to install a typical sensor rather than the "on a bolt" sensor that the DigiPanel currently uses.
And - considering the same strategy for water temperature too.
Thank you for all of the expertise shared here.

Steve.
I believe Summit Racing sells all the weld on Bung plugs you need. I installed one on my oil pan, trans pan and final drive cover. All worked out well.
There are also after markket plugs which I am sure will do just as good.
Good Luck and take care,

I am not familiar with the digipanel, other then it does have bolt on sensors.....
weld on bungs for the tranny pan are easily bought from napa, summit, or amazon.... and I recommend that for 2 reasons. 1. tranny temp sensor. 2. works as a drain plug as well!

Applied GMC now sells the DigiPanel. They can refer you to a technical guy who may be able to assist with your question about the senders. As far as the trans temp, consider getting a finned aluminum pan from ragusarv.com -- they have a fitting built in along with a drain plug. The Ragusa pan is reported to help with cooling although some folks don't like it because it protrudes a bit lower than stock, increasing the risk of impact damage.

I have a Ragusa finned aluminum transmission pan, and it has a drain plug
as well as a plug for a temp sending unit, which I also use. Transmission
temp rarely moves the needle. That finned pan works very well and it has an
extra quart capacity. A good investment as far as I can tell.
I also removed the final drive pan and welded in a bung for a temp.
sensor. That one makes me nervous. Final drive temps exceed 300 ° Farenheit
on heavy uphill climbs. Before I had the temp sensor, I rarely even thought
about final drive temps. I use a synthetic final drive lube as well as ATF.
CHEAP INSURANCE.

Which ATF do you recommend?

I use Valvoline Synthetic. It was what Manny recommended in my
remanufactured transmission. I suspect that other brand names would work as
well. But, that is the name brand that I have always used. Brand loyalty
and all that, I guess.
