Automatic Transmission Cooling System
Your automatic transmission works better when its cool. That’s why your vehicle is equipped with a transmission cooler, which keeps operating temperatures as low as possible. The transmission cooler is responsible for cutting down on heat in your automatic transmission.
Your vehicle’s transmission cooler, or automatic transmission oil cooler, is either built to or in front of the radiator. The radiator is responsible for engine cooling, so it would make sense that the transmission cooler teams up with this integral part.
The transmission cooler works to keep the automatic transmission fluid (ATF) at the proper temperature. It achieves this through a series of automatic transmission hoses or automatic transmission pipes that run through or in front of the radiator and back to the transmission. Air flowing through your vehicle’s grille cools the ATF flowing through these pipes and hoses.
Automatic Transmission Fluid (ATF)
Automatic transmission fluid (ATF) is incredibly important to your transmission system because it cuts down on friction and heat produced by moving tranny parts. It is usually red and has a fairly light consistency.
ATF works its way into your transmission through the automatic transmission gear pump, or automatic transmission front pump. This pump draws the ATF from the sump in the bottom of the transmission and feeds it to the rest of the hydraulic system.
Checking your automatic transmission fluid level is as important as it is easy. First, find your ATF fluid reservoir, unscrew the cap and the automatic transmission dipstick should be attached. Now, wipe the dipstick clean, re-dip and pull it out again (your vehicle should be idling in most cases). If the fluid is red and fairly thin and covers the space between the high and low lines, you’re looking good. If the ATF is brown or black and smells burnt, it has most likely overheated and must be replaced.
A Quick Fix to Many Transmission Problems: Automatic Transmission Filters
With automatic transmissions, it is incredibly important to change a clogged . A clogged filter can cause a variety of transmission problems that may sound expensive (but don’t have to be). Most drivers never change their transmission filter, and many transmission problems can be solved by swapping out this part. (For maintenance purposes, it’s wise to change your
transmission filter every 30,000 miles or so.) If you’re not sure when your filter was last changed, ask your local auto shop to check it out.
