2012-2013 F-150 4×4 – 3.5L – Transmission Fluid Leak – Built On 5/23/2012 And Through 6/3/2013
2012-2013 F-150 4×4 with 3.5L built on 5/23/2012 and though 6/3/2013 can exhibit a transmission fluid leak from the bell housing.
For visible leaks clean the location on the transmission and add Dye-Lite ATF/Power Steering Fluid Leak Detection Dye to the transmission fluid.
Refer to the Workshop Manual (WSM), Section 307-01 Leakage Inspection.
For vehicles built within the build dates mentioned please look closely to approximately the 4 o’clock to 6 o’clock area of the case ribs in the bell housing if the leak is coming out from this area replacement of the transmission case will be required refer to WSM 307-01 Transmission Disassembly.
For vehicles that are not leaking in that specific case area please follow the appropriate WSM Procedure based location of the leak.
- Prevents overheating, reducing elevated operating temperatures up to 40 degrees Farenheit - Optimizes total transmission performance
- Eliminates transmission fluid foaming and oxidation and reduces wear throughout the transmission
- Eliminates clutch chatter and torque converter shudder; Softens and modifies harsh shifts making them quicker in duration
- Extends fluid life / Raises the thermal and oxidative stability of the fluid
- Only protectant that increases the fluid’s ability to transfer heat / Protects new seals and permanently restores older seals to a like-new condition, without adverse side effects
