FLUIDS
Automatic transmission fluid may well be the most important part of a modern automatic transmission. It has been said that the transmission fluid is the "life blood" of the transmission. Therefore, it is very important that transmission fluid have the same performance and durability as any other part in the transmission.
Transmission fluid exerts force to move internal transmission parts. It lubricates internal transmission parts while acting as a coolant to carry heat away from the transmission's clutches, torque converter, and retarder sections. The heat is extracted and the transmission fluid is cooled in the cooling circuit. Various filters, built into the system, keep the fluid clean and free of debris.
Transmission fluids are designed to stay in the transmission for long periods of time. The better the fluid quality, the less you will have to maintain it. Allison Transmission has worked with lubricant manufacturers and their scientists over the years to continuously improve automatic transmission fluids.
Transmission fluids technology has come a long way of what can be accomplished through advanced transmission fluid technologies. Modern transmission fluids, that have the TES 295 TM Approval are capable of lasting many hours and many miles without the need for change in a wide variety of vocations and applications ranging from school buses to very large mining equipment. Extended drain intervals translate to reduced maintenance and improved productivity.
Among other things, the fluids webpage includes links to a list of approved Allison C4 products for Off Highway applications, the latest approvals to the Allison TES 295 TM specification, as well as the TES 389 specification. There is also a link to oil analysis. Oil analysis can be very useful in determining the life of your automatic transmission fluid. Allison has developed a kit that makes it simple and easy to monitor your transmission fluid no matter how many vehicles in your fleet. It's all automatic !!!! Simply purchase the kit, send in the samples, and get the results via mail, email, or the web. It's that easy. Allison's computer based analysis will look at the results and make a recommendation based on the condition of the fluid.
