Transmission Oil Cooler

Because of the tremendous heat generated in an automatic transmission, an auxiliary transmission oil cooler is an economical way to help protect against costly transmission repairs. Automatic transmission fluid (atf) cools, lubricates and cleans internal transmission components. When transmission temperatures exceed 93°c (200°f), the ability of atf to perform is greatly diminished. Subsequently, the life span of the fluid, seal and moving parts are significantly reduced. Higher internal temperatures also increase the wear rate of the friction and clutch plates.

Excessive transmission heat is caused by the following driving conditions:

  •  Towing
  • Climbing
  • Stop and go traffic
  • Carrying loads
  • Hot driving conditions
  • Driving in sand or snow

Davies, Craig transmission oil coolers can reduce the atf's temperature by as much as 33°c (60°f).a reduction of just i 1°c (20°f) can double the life of an automatic transmission, the fluid and all internal parts.

Two types of transmission coolers:

  •      Ultra-cool®' tube and fin style
  •     Hydra cool® plate and fin style

The hydra-cool® transmission oil cooler is an effective and economical way to keep the transmission at its optimum operating temperature. High efficiency turbulators in each tube direct the fluid for superior heat transfer. Hydra-cool's® unique plate and fin design allows for effective cooling, yet requires 33% less space. The hydra-cool's® compact design is perfect for applications where available mounting space is limited.

All Davies, Craig transmission oil coolers are 100% pressure tested to ensure the reliability and durability of the product. Both ultra-cool ®` and hydra-cool® come complete with the necessary accessories and instructions for quick and easy installation.

*All coolers come complete with a mounting kit, flexible hose and hose clamps.
