Bushwhacked! Keys to Avoiding Preventable Bushing Problems
The stator tube bore is tapered in 6F35 units due to OE manufacturing conditions. The taper MUST be removed by machining the bore entrance before installing Sonnax bushing. See instructions for details.
Use of an arbor press is required for correct installation. Do not use a hydraulic press or a bushing driver/hammer combination to install, as doing so may distort the bushing and cause fitment issues.

Stator bushings in Ford Gen. 1 and 2 6F35 transmissions have a tendency to wear out prematurely due to sub-optimal material composition of the OE bushing. Because the stator bore is tapered, it is common for replacement bushings to have retention problems. Complicating this further, some aftermarket replacement bushings are made from bronze without steel backing. The result is that aftermarket bushings routinely spin in the bore, very often on the test drive after replacement. This failure results in TCC slip, no TCC and codes P0741 and P1744. Machining the bore and installing Sonnax stator support bushing 144036B eliminates spinning and premature deterioration for worry-free operation.
