Can a bad TPS cause transmission problems?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems. The TPS can also send bad input that ends up stalling the engine at any time.
Why does a valve body go bad?
When the lubricant used becomes worn out or leaks out, the metal parts of the transmission valve body rub against each other and wear out, causing tiny metal pieces to find their way into the transmission fluid. The effect of this is that the gears may stick and in turn fail to work as required.
Can MAF sensor cause transmission problems?
A problem with the air flow sensor could also alter the shifting pattern of the automatic transmission. A bad MAF can cause hard or incorrect shifts. A faulty MAP sensor can cause late, harsh shifts, early / soft shifts, or even prevent the transmission from shifting at all.
