ASE A2 In-Vehicle Maintenance and Repair

Question 1

After a transmission range sensor is replaced, the engine cranks in Neutral but not in Park. Which is the most likely cause?

Accepted Answer

The range sensor is not aligned with the manual shaft

Answer

Park and Neutral should both close the start circuit. If only Neutral does, the sensor's alignment with the manual shaft is off.

Question 2

ATF is seeping from the lower bell housing inspection area, and the back of the engine is dry. The fluid is red and the leak is at the torque converter hub. Which seal is most likely leaking?

Accepted Answer

Transmission front pump seal

Answer

ATF at the converter hub points to the front pump (converter hub) seal. The rear main seal would leak engine oil.

Question 3

When reinstalling a transmission pan with a new gasket, which procedure best prevents leaks and a warped pan flange?

Accepted Answer

Tighten the bolts in a crisscross pattern to the specified torque in stages

Answer

Staged, crisscross tightening to the specified low torque, usually in inch-pounds, gives even clamping. It avoids crushing the gasket or distorting the pan.

Question 4

The ATF on the dipstick is milky pink and the cooling system level is dropping. The transmission cooler is inside the radiator tank. What is the most likely cause?

Accepted Answer

A leak between the cooler and coolant passages in the radiator

Answer

Coolant and ATF mixing through a failed radiator-tank cooler gives pink, milky fluid and a falling coolant level.

Question 5

A vehicle clunks and the engine visibly rocks each time the shifter is moved from Park to Drive. The transmission shifts normally otherwise. Which component should be inspected first?

Accepted Answer

Powertrain mounts

Answer

Excessive engine movement at engagement points to worn or broken engine or transmission mounts.
