F-Trim Valve Sleeve (2004-Earlier)
Price: $16.18
Part Number: TAT-37000-03-SX
The F-trim valve is controlled by a PWM solenoid that continuously strokes the valve. When the valve end sleeve becomes worn from constant oscillation, it allows TCC PWM pressure to leak to exhaust, inhibiting the valve from stroking against the spring and causing converter apply concerns, TCC surge, TCC slippage, code P0741 and overheating. The valve end sleeve can also become worn enough to cause the valve to stick, causing converter release problems as well as apply problems, depending on which direction the valve gets stuck. The Sonnax valve end sleeve is wear-resistant and has high lubricity characteristics to restore the F-trim valve to normal operation.

Features & Benefits

Sleeve is made from high-quality aluminum for increased wear resistance.
High lubricity ensures proper valve operation.
Drop-in replacement allows salvage of costly valve bodies.

Note: The F-trim end sleeve, valve and spring shown here are used in(02 to mid-04)valve body castings. These F-trim components differ from those in the later application, identified by the larger, high frequency TCC solenoid.
