I have the above code in ABS and tranny module. Appears to come back after erase.
What might be causing the code?
What are effects of the code?
Suggestions for troubleshooting?

Check and clean the connecters for the TCM and ABS module. My default answer for wonky errors is its usually a bad ground.

For myself, when I have had those codes, I would have to clear the codes from abs, tcu, and ecu to make it not come back.
