How often should I change my
We normally recommend changing your transmission fluid
every 20,000 miles on a new car.
If you are driving a used car with under 50,000 miles the same rule
should apply. If however your car has over 50,000 miles on it and you do
not know when the last time it received a fluid change was. We do not
normally recommend servicing your transmission at that time. You may cause
more problems than you may expect. It is normally better to wait until you
replace the transmission and start a regular servicing routine at that
time and maintaining it afterwards.
I have a leak. Can you tell
how much it would cost to repair it?
There are several places that a
transmission can leak. They include: the pump, shift lever seal/s,
kickdown seal, electrical connection/s, governor cover, speedometer seals,
rear output seal or axle seals, servo cover/s, filler tube, throttle
cable, pan, side cover, cooler lines, and differential cover. The real
question is: What is/are the source/s of the leak/s. The unit must be
visually inspected to determine the source/s of the leak/s. So, the answer
to the question is: No, I can't without seeing the vehicle first.
Will it hurt to overfill the
In a word, no! It is possible that gross
overfilling can cause the fluid to be subjected to moving parts and become
aerated which could cause abnormal operation. You may also notice leaks
that normally would not occur.
How long will a transmission
There is no accurate answer to that
question. The mileage or time of use before major problems occur will vary
greatly, and therefore, I don't see a correlation between mileage and
expected transmission failure. It is not unusual that the first few years
after a newly designed transmission hits the road, that early failures
occur. But, in later years with updates to the original design, the units
become more reliable. The three major factors in the life expectancy of a
transmission are periodic maintenance, maintaining proper fluid level, and
