Our one answer to most questions about diagnosing a problem is to find a specialist that you can trust. Call KJ Transmissions as your specialist for answers to all of your transmission questions.


How do I check my 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 operation temperature. Remove the dipstick and wipe with a rag. Insert the stick fully and remove. Look at both sides of the stick and verify the same indication. Repeat the process.

Is it OK 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.

Will my transmission have to be removed and inspected for an estimate?

No, we can give you a preliminary estimate for repairs before any work is performed.

I have a transmission leak, can you tell me how much it will cost to fix it?

All vehicles are different and have to be inspected at our shop to give an accurate diagnosis and cost of repair.

Should I get rid of my vehicle after my transmission is repaired?

No, an accurately repaired transmission should last at least as long as the original, and in some cases even longer due to updated repair procedures and advancements in technology.

How long does a transmission normally last?

There is no accurate answer to that question.  The mileage or time of use before major problems occur will vary greatly, and therefore there is no 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 might 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 temperatures resulting in a longer life, but not all transmissions can us the synthetic fluid.
