Transmission Temperature Support LS2 4L70E

[Sherlock]

I pulled out my hp tuners to see what my transmission temp was so I could do a before and after transmission cooler temp comparison, and it does not work, just reads 32 degrees. Is there something I can do to get this to work? I have the newest update 2.1.12. Am I missing something?

Any help would be great.

Thanks
Justin

It looks like it isn't supported ... I see the same thing when we sniff the CAN bus and query for trans temp via the extended GM OBDII PIDs.

It does respond, but always with the same value (which when converted comes out to 32 degrees F).

Same issue with the SSR ambient temp shows 32f ?
