Frequently Asked Transmission Questions

We get many questions on a daily basis about transmissions. Customers want to know everything they can about transmission maintenance and the costs involved. Below are some common examples of transmission concerns and questions that we come across.

How do I check the transmission fluid level?

Always check the fluid level with the engine running (except Honda), the transmission in “park” (except Dodge products which should be in neutral with the emergency brake applied), 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.  Repeat the process.

I have a leak.  How much will it cost to repair?

Of course there is no simple answer to that question. The real question is where exactly is the source of that leak.  Often customers can only see the bottom of the unit, and therefore conclude that the bottom pan gasket is leaking. That may not be the case. Often the leak is from above and running down and around the pan. Therefore, it is most important to have the leak visually inspected.

Is it okay to drive with a transmission leak?

A minor or slow leak will allow you to drive as long as you maintain the level in the normal range.  Figure out the rate of loss and replenish fluid as necessary.  It should be obvious that if fluid is running out as a stream, that you won’t go very far.  A transmission will usually operate “normal” until the fluid loss is a quart or more.  Then the unit will start to malfunction and internal damage will occur. What started as only a leak can result in a major repair bill if ignored.

How long does a transmission normally last?

The 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.

How can I make my transmission last longer?

Make sure to check your fluid level and condition periodically. Repair any leaks or problems promptly. Service the unit on a regular basis, and add an auxiliary cooler if the vehicle is used for towing, commercial, or high ambient temperature climates. Synthetic fluid may benefit some applications by lowering operating temperature resulting in a longer life, but not all transmissions can use the synthetic fluid.
