On my ’08 Wrangler, my ODB Scanner only shows Ambient Air Temp, Catalyst Temp Bank 1 &2, Engine Coolant Temp, and Intake Air Temp. Nothing about transmission temp.

On the other hand since it does have Ambient Temp and Intake Air Temp I could see if a CAI actually makes a significant improvement in temp.

 

I asked the same question a couple weeks ago:

"When will ScanGage be able to monitor and display 2008 Jeep Wrangler 4 speed automatic transmission temperture?"

This was the answer:

"Hi,

I wish I knew when. Hopefully in the next couple of months.

Regards,

Linear Logic"

If a lot of us ask the same question, it might speed up the process.
They have already published the codes for Ford and GM cars/trucks.

 

Update on ScanGauge Trans temp for 42RLE:
This is their answer to my latest inquiry:
Hi,

We plan on having at least transmission temp codes for all vehicles. Unfortunately we ran into a snag trying to extract them from vehicles including Chrysler. Hopefully we will have them in the next couple months.

Regards,
Linear Logic

 

BUMP for an old thread. Anyone with a Scangauge figure out how to monitor transmission temps??
