Therefore, there are two different scales for checking the level of hot fluid and cold fluid on the level gauge. Though the fluid level can be checked without warming up the fluid on the “COLD” range, it is recommended to check the fluid level when the fluid is at operating temperature. 1) Yellow handle 1) 2) 3) 4) HOT range COLD range Upper level Lower level ! Checking the fluid level when the fluid is hot SAE viscosity No. and applicable temperature 1. Drive the vehicle several miles to raise the temperature of the transmission fluid up to normal operating temperature; 158 to 1768F (70 to 808C) is normal. 2. Park the vehicle on a level surface and set the parking brake. 3. First shift the selector lever in each position. Then shift it in the “P” position, and run the engine at idling speed.
