WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
Dye-Lite® ATF/Power Steering Fluid Leak Detection Dye 164-R3701 (Rotunda) (specifically formulated for ATF) is used to detect a transmission fluid leak.
- Add dye to the transmission fluid. Use 30.0 ml (1 oz.) of dye solution for every 3.8L (4 qt) of transmission fluid.
- Start and run the engine until the transaxle/transmission reaches its normal operating temperature. Observe the back of the cylinder block and top of the torque converter housing for evidence of fluid leakage. Raise the vehicle on a hoist and run the engine at fast idle, then at engine idle, occasionally shifting to the DRIVE and REVERSE ranges to increase pressure within the transaxle/transmission. Observe the front of the flexplate, back of the cylinder block (in as far as possible), inside the torque converter housing and the entire case until fluid leakage is evident and the probable source of leakage can be determined.
