Do check the automatic transmission fluid every 1,000 miles for its level, color, and smell. Low levels, a dark color and a burnt smell are all tell tail signs of trouble ahead.
- A Low fluid level is an indicator of possible seal leakage; and or malfunctions within the transmission or it's related components.
- Leaking Fluid can be your transmissions way of calling for help. If leaks are detected you should call Mr. Transmission right away. Don't put it off or ignore the obvious.
Do be aware of any changes in your vehicles driving characteristics. Should you notice slippage, strange noises of any kind and early or late shifting, have Mr. Transmission diagnose it immediately.
- A quiet vehicle, operating properly is a "Safe Vehicle".
- Have Mr. Transmission check your vehicle to determine if defects exist and to evaluate if the vehicle is road worthy and safe.
- It costs you little to check.
Do maintain a properly tuned engine. Many vehicles will utilize the engine's vacuum as their source to control transmission shift quality and hydraulic pressure. A properly tuned engine is extremely important to the life of the automatic transmission.
Do check the vehicles cooling system on a regular basis. A major cause for premature transmission failure is excessive heat. Make all the necessary repairs immediately.
Do scheduled maintenance according to vehicle owner’s manual.
Do have transmission fluid checked when having oil changed.
Do make sure you come to a complete stop before moving gear into another range.
Don't wait until its too late. From a standpoint of Economy and Safety, that type of decision-making simply does not make sense!
Don't rock a vehicle back and forth whenever you are stuck in mud, sand or snow. This may cause your transmission to operate in excess of 400 degrees Fahrenheit. At that high of an operating temperature, you are most certainly in for an immediate transmission failure.
Don't overload the vehicle. Heavy loads will also cause overheating and greatly reduce your transmission life.
Don't forget that early diagnosis and repair are your best bet. This leads to minimal operating costs and a long, safe, useful service for your vehicle. Left unattended, even the smallest of malfunctions can and usually does, lead to serious major repairs.
Don’t drive a vehicle with low or no transmission fluid.
Don’t change gear ranges from drive to reverse when your vehicle is moving.
Don’t drive your vehicle when there are transmission problems, this may cause further damage.
Don’t drag race your vehicle as it puts unnecessary strain on your transmission.
Don’t drive in 4x4 range on dry pavement unless vehicle is all wheel drive or automatic 4x4.
Don’t drive on spare tires or mismatched tire sizes with front wheel or all wheel drive vehicles for extended periods of time.
