FAQs

Why is servicing your transmission so important?

It is very important for a transmission to be serviced on a regular basis.  We recommend either every 12 months or 20,000kms.  This will ensure that the transmission is thoroughly checked and minor repairs fixed before they cause major breakdowns.  Most car owners do not know that a transmission exists in their car until a problem occurs.  Transmissions need to be serviced before a problem occurs - never wait for a problem to occur.

We at Aspley Automatics all Customers are notified every 12 months with servicing reminders in the mail at no charge

In the long term you will have to service your transmission as the transmission wears all the foreign particles have to go some place and that’s in your filter so a service is recommended on all transmissions from first service at around 80,000 then around every 20,000 there after

My book said it’s filled for life

This is correct on as far as the oil goes but as we have explained above the filter should be serviced or replaced and then all new oil should be fitted in your automatic transmission

I am told my transmission is a sealed unit

What this means is that the manufacturers have taken out the dip stick (filler tube) and you now require a fully qualified and trained automatic transmission specialist to check or top up your transmission fluid hear at ASPLEY AUTOMATICS we can do this for you.

WE DO NOT RECOMMEND TRYING THIS AT HOME, LEAVE IT TO THE EXPERTS

Automatic transmissionI have an oil leak. Can you tell me how much it will cost to repair it?

There are numerous places that a transmission can leak.  They include: the pump, shift lever seal/s, kick down seal, electrical connection/s, governor cover, speedometer, rear output seal or axle seals, servo cover/s, filler tube, throttle cable, pan, side cover, cooler lines, cooler and differential cover on front wheel drives.

What we have to do is find the source/s of the leak/s.  Most people can only see the bottom of the unit, and therefore conclude that the bottom pan gasket is leaking when, in reality, the leak is from above and running down and around the pan looking for the lowest point to drip from. Therefore, it is imperative that the unit be visually inspected by ASPLEY AUTOMATICS to evaluate the leak situation!

So, the answer to the question is:  No, I can't without seeing the vehicle and Placing it up on our hoist.

Can I drive my car with an oil leak?

It depends on the rate of fluid loss.  A minor or slow leak will allow you to drive as long as you maintain the level.  You will have to establish the rate of loss and refill as necessary.  It should be obvious that if fluid is running out like your garden hose you won't go very far.  A transmission will usually operate "normal" until the fluid loss of a liter or more.  Then the unit will exhibit a loss of drive or slipping symptoms then internal damage is occurring now a leak can result in a major repair bill if ignored!

Will it hurt to overfill the transmission?

In a word, no!  Although, it is possible that 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 ordinarily would not occur, example it may leak out of your vent (breather)

Will overfilling blow out seals?

In a word, no!  The transmission case is vented preventing pressure buildup in normally un-pressurized areas.  Severe overfilling can raise the fluid level such that the transmission may lose fluid through the vent (breather) or leak from seals that are above the normal fluid level, but the fact remains that the seals that are under pressure and those that are not will not change because of the fluid level.

  • Check the fluid level and condition periodically,
  • Repair any leaks/problems promptly,
  • Service your automatic on a regular basis, and
  • Add an auxiliary cooler if the vehicle is used for towing.

Full synthetic fluid (oil) may benefit some applications by lowering operating temperature resulting in a longer life, but not all transmissions can use the synthetic fluid.  Check with Aspley Automatics for their advice on your specific application and needs.

 

How do I check the transmission fluid level?

Always check the fluid level with the engine running with the transmission in PARK and with the engine at operating temperature.   Remove the dipstick and wipe with a rag.  Insert the stick fully and remove.  Look at both sides of the stick to verify the same indication on each side.  Repeat the process 2 or 3 times.

The reason to check both sides of the dipstick is that after the fluid circulates through the transmission, it dumps back into the pan area and will creates an uneven level and some fluid will "slosh" onto one side of the dip stick and give a false reading.  Some transmissions are worse than others.

Also, the difference of fluid temperature will affect the measurement.  The fluid volume expands when heated to operating temperature.

If you have added transmission fluid, go through the same procedure, but repeat the process several times before you look for a reading.  Some will give a false reading.

If the fluid level is low, you have a leak!  Transmissions do not consume fluid.  Have the leak diagnosed and repaired by Aspley Automatics ASAP to prevent more serious problems.
