The excessive heat can destroy parts of the torque converter and transmission. A lot of racing stresses the transmission, causing it to heat extremely quickly. It's been established that for every 20degF your transmission heats up, it reduces the life of your transmission fluid and your transmission by half. This is well-known and widely acknowledged. However, a lot of people are still curious about how to solve this problem.

These are our recommendations for drag racing of all kinds:

If your vehicle is driven in the street or back to your pit area after passing, always run an air conditioner and, if you can, an electric fan. We see numerous customers who have looped cooler lines. In the case of a powerglide 4L60E the looped cooler line dumps the automatic transmission fluid at its highest temperatures (directly through the torque converter) into the clutch and gear set packs. This leads to early failure of all the components.

We recommend a cooler with a high-end design. We have used 4L60E transmission. For high-powered setups where an input shaft that is ringless is required, choose a pump that is designed to ensure cool flow. The high-volume pumps all keep a good cooler flow and pressure when used in conjunction with our ringless input shaft. The input shaft with no ring in an OEM model pump will have no pressure or cooler flow that results in all of the super heated transmission fluid dumping directly into the gears and clutch packs.

A cooler circuit won't be a problem for 4L60E the car is being towed to the start line and then tow back to the pit after you've completed your pass. Therefore, it is OK to have a looped cooler line or an input shaft setup with no room for the cooler circuit. In this scenario, the transmission and torque converter will still be very hot even after the transfer. Sharp Stuff recommends using an external cooler. We've also had some performance using a powerful fan or leaf blower directly aimed under the car for an effect of cooling.

Use a quality ATF

We select a Lucas Oil blended fluid. Synthetic and semi-conducive fluids can handle heat better than traditional fluids, and they can also provide better lubrication.

It can be fatal to heat

When you are in the middle of the steamy summer, it is even more extreme. It is nevertheless possible to make a difference in the result of your drag racing car in the event of any issues with its performance or parts which have failed.

Conclusion:

It's often not thought of that automatic transmission is a crucial aspect of owning a car. The excessive heat damages the parts of the torque converter and transmission and can cause a decrease in performance, shorter time to repair, and more expenses. These easy steps will ensure that your vehicle stays operating cool and comfortable for many years.
