Transmission Parts Ford 5R110W Pump Valve / Sleeve

Symptoms:

Code 1744, 1783
Low line pressure & TCC concerns

Cause:

Excessive valve and bore clearance allows critical line pressure to exhaust causing low line pressure and TCC concerns.

Correction:

Sonnax oversized pressure regulator valve kit restores the correct valve/bore clearances and line pressure control as well as prevents future wear in this area.

Warning:

A specially designed oversized base plate VB-06 must be mounted to the VB-FIX to accommodate the 5R110W pump body.

Ford 5R110W units may exhibit various line pressure and converter problems due to excess wear in the pressure regulator bore. Deterioration of the bore prevents the valve from providing higher line pressure as fluid is pulled into the suction port. The pressure regulator valve also controls fluid flow entering the converter and lube circuits, which can be reduced resulting in multiple TCC concerns and trouble codes. Installing Sonnax oversized pressure regulator valve kit 36940-03K restores the hydraulic integrity of these circuits for proper line pressure control.

Note

Three pump generations were produced, with varying casting hardness. The Sonnax reaming tool kit used must be matched to the hardness of the pump to extend reamer life and bore finish quality. Sonnax reaming tool kit F-36940-TL3 is for use with first generation pumps, while F-36940-TL3C can be used with all pumps regardless of pump generation. See instructions for details.
