if the cluster dose need to be reprogrammed then it has to do with one of the 4 chips on the cluster board, when i take mine back apart ill do some looking around for the chip numbers so at least i could narrow down what chip needs to be programed
How do you know that your trans temps ever got hot enough to move the needle? Were you towing a trailer, loaded heavy, or do you have an aftermarket converter? A mostly stock setup will not build a lot of heat in the transmission, and trans temps will be really low.
I'm just asking for the sake of asking. IDK if the cluster needs flashed or something silly like that.

my trans set up:
Corvette Servo w/2 spacers, Hayden 678 cooler, Transgo HD-2, Transgo separator plate, Sonnax pinless forward accumulator piston, 1-2 aluminum accumulator piston, the "beast", raybestos stage 1, TB converter

My truck have stock converters, even up north in 5 degree weather the transmission gauge still showed temp at highway speeds. There is a ebay vendor that will program the cluster so the added gauge will work. I plan on sending one in for my RCSB, will take cluster apart when it gets back to see if it was programmed or if any resistors where added to the board.

I took the truck out this morning for a 40 min drive and still nothing on the trans temp gauge. so i took it back apart for the chip numbers and found 2 more chips under the gear indicator and under the info display but couldn't read them due to the location then I did some looking for data sheets
I couldn't find much but i did find that the
L9203-02: is the display controller/driver

Tranny gauge install

My pan temp was 170 F. I have a 5.3 4l60e combo with 3.73 gears 265/70r16 tires and stock converter and stock tranny cooler. I have never been able to get my trans temp higher than 180. If you are running a monster tranny cooler, and/or the air is cool, I don't believe the fluid temps would climb that much, as long as you are moving.
The only time I saw tranny temps get high was with my 92 silverado. basicly same set up, 350 and 700r4 with 3.73 gears. I had a 2000 stall converter and was towing 3rd gen Camaro on a rental trailer. I had a B&M trans temp gauge installed. In several hours of stalled traffic on the freeway with the engine idling, the temp got over 250. I had to put it in neutral and rev the engine to cool'er down. Once we started moving over 25 MPH it cooled down on its own.
SOOOO, any update?

yes there has been updates but none good. I bought a 2500 cluster (with trans temp) and took it apart and all the chips part numbers match, also im 99.9% sure the chip that needs to be reprogrammed is the 9399059AB (this is also the chip that holds the mileage data).
to reprogram that chip is going to take advanced knowledge of hex editing/eeprom burning as well as knowing what lines to edit and what to edit the lines to in the hex-editor. ive gone as fair as i can go with my current tools
