Default 99 vp tranny code p0702
I know the code means trans control sytsem electrical.
But what does this mean?
Car runs fine for 10-15 miles when fluid warms up trans fault light comes on and trans goes into limp mode. Actually drives smooth just slow from stop .
Any ideas.

This code is for a TCM internal power supply switching malfunction, either the harness or the TCM may be bad. You will need to get them tested or replace them if you are sure what it is.

Check harness pins 52& 53 for short, open or high resistance. If they are good, you may need a TCM.
