the check engine light came on and I put a tester on the OBD diagostic cable and found two problems
1. P 1739 "manufacturer Control transmission"
2 P 1519 "manufacturer control vehicle speed Idle control auxilliary input"

Doe anyone know if these are serious problems? The transmission runs fine and it idles ok (but the engine did start to miss but seems ok now)

I know that there was an extension on the transmission warranty but I am beyond that extension. The car has 83,000 miles.
Thank you
