(D) Neither A nor B. 2. A defective throttle position sensor can cause all the following electronic transmission problems except: (A) harsh upshift s. (B) downshift bump. (C) converter vibration. (D) improper shift speeds. 3. Technician A says that a transaxle suffering from gear skipping may shift from first to third gear.
