Answers.
Failing transmission oil pump? Why important symptoms - Correct Answer A transmission
oil pump is an integral part of the transmission unit. It serves the critical purpose of
providing lubrication to the valve body and other essential internal tranny components. It
also transports transmission fluid to the tranny cooler, cooling the fluid.
(SYMPTOMS NOISE(IMPORTANT Ase 2)
One of the common signs of a failing transmission oil pump is a whining noise when
driving. . [[A notable sign that it's a failing tranny oil pump is consistent at all speeds.]]
Also, there will be metal shavings in the bottom of the transmission crankcase at removal.
This means the tranny oil pump is wearing out.
A failed tranny oil pump is usually caused:
1. Dirty transmission fluid causing the blockage,
2. Bad front seal causing transmission leaks
3. An extremely clogged transmission filter causing restricted fluid flow.
It can also be caused by poor lubrication causing friction, defective transmission
crankcase causing leaks, etc.
Vehicle sludges at low speed but normal at high speeds it drives normal - Correct Answer
torque converter stator is freewheeling
Vehicle sludges at high speed but normal at low speeds it drives normal - Correct Answer
torque converter stator is seized causing no torque multiplication
Digital Multi-Meter(DMM) is set up to measure resistance of a solenoid. The solenoid has
a veritable resistor and a solenoid switch integral (always open). The DMM measure 25
Ohms all the time. - Correct Answer Their is a faulty switch stuck closed causing
resistance of 25ohms reading all times.
Vehicle stall speed is within specification, Transmission fluid is dark in colored. Although
when vehicle is accelerated in Neutral, vehicle feels load on engine.
, hint: Stall speed is within spec. - Correct Answer If the transmission pump is going bad, it
can't properly pressurize the transmission fluid. This leads to gears slipping and a lack of
power when accelerating. transmission is slipping, it's likely because there's not enough
pressure in the system. A failing transmission pump can cause this. Without enough
pressure, the gears can't move smoothly, and you'll lose power when you try to
accelerate.
Causes of STALL SPEED BELLOW SPEC. - Correct Answer ~ EXHAUST
BLOCKAGE/CLOGGED
~ FREE WHEEL STATOR
~ ENGINE PERFOMANCE
Cause of STALL SPEED ABOVE SPEC. - Correct Answer ~ TRANSMISSION
GEAR/BANDS/CLUTCHES ARE SLIPPING.
What cause an automatic transmission output shaft seal to worn out? - Correct Answer A
worn extension housing bushing can cause vibration and binding u joint or case
misalignment can cause this accelerated wear.
Technician A states compress air and soft cloth could be use to dry an Automatic Valve
Body.
Technician B states using a crocus cloth can be great practice dry a Valve Body. - Correct
Answer Technician A is right: never use a crocus cloth(an abrasive sheet similar to sand
paper)to dry valve body.
Crocus cloth only use to remove defects such as nicks, scratches. If defects to deep
replace parts as needed.
The MIL light is activated. Technician states all gear are harsh and firm.
Hint: A throttle position sensor not answer on test due to not causing line pressure
increase only lost signal. - Correct Answer Accumulators are shift modifiers that affect
Transmission shift timing and quality. With out an accumulator the device applies
suddenly and harsh shifting occurs.
ex MIL light on CODE P171D Chevrolet possible causes..
~Transmission accumulator fluid pressure accumulator harness is open or shorted.
