The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the Vehicle Speed Sensor is faulty, however, at times, the driven gear inside the transmission is at fault. Replace the Vehicle Speed sensor and inspect the driven gear upon sensor removal.

Mercury Topaz Problems
Poor rubber material used in the motor mounts can cause them to fail, leading to a knocking noise or lifting sensation on acceleration. The motor mounts will need to be replaced with revised parts.
Fuel pump failure can cause the engine to crank but fail to start. Diagnosis will show insufficient, or no fuel pressure, and fuel pump in the fuel tank will need to be replaced.
If the throttle lever is out of adjustment, or the grommets are missing / broken at the throttle or transmission, the automatic transmission can shift hard. Replace the grommets as needed and adjust the throttle lever.
Outdated software in the engine control processor can cause poor engine performance, hesitation on acceleration, and possible stalling problems. The processor will need to be replaced to get the updated calibration.
