did they replace the transmission input speed sensor?
After you clear the codes yourself... how long before it throws the code again?

Can I fix it? Yes I can.

Relist: No answer yet.
As I stated on my question. Dealer and I changed all sensors on engine including computer.Timing and chains, grounds, Ing.coils and fuel sys. checked out ok.Also compression.They were guessing and changing parts I didn't need.After lots of hrs and money they gave up.It was in shop fo 6 wks. and went in limp mode and came out the same.BUT it shows a code 59 which is a transmission imput sensor is bad. Is this the cause and can I change it myself?
