Figure 100–15 A cutaway section of a typical radiator showing the automatic transmission fluid cooler. The heat from the automatic transmission fluid is released to the engine coolant. The engine coolant also warms the automatic transmission fluid after a cold start. CAUTION: Because the lube oil uses the ATF flowing from the cooler, if there is a blockage in the cooler, the transmission/transaxle may not have enough fluid to properly cool or lubricate the bearings <strong>and</strong> bushings inside the unit, leading to wear <strong>and</strong> eventually premature failure.

PLANETARY GEAR SETS In a manual transmission, different gear ratios are obtained by sliding the gears into mesh. Torque flow must be momentarily interrupted (accomplished by using a clutch) before the gears are shifted. With an automatic transmission there is no driver-operated clutch, so gear shifts are not made by sliding gears into mesh. Automatic transmissions use a planetary gear set system that does not require manual gear shifting or an interruption of torque flow to change gear ratios. Continued
