Product Description

4R70E, 4R70W, 4R75E, 4R75W, AODE

Solenoid Regulator Valve Kit
Part No. 76948-14K

Requires: 

• 76948-BST2 (Recommended)

In Ford 4R70E, 4R70W, 4R75E, 4R75W and AODE transmissions, solenoid regulator valve ensures that the solenoids are not flooded with more pressure than they can exhaust. When the regulator valve sticks, the pressure becomes too high and the unit may exhibit wrong gear starts. A more common problem is wear in the solenoid regulator bore, causing working pressure to be too low. Low solenoid pressure results in no 2nd, no 3rd or a shift to neutral on a 3-4, 4-3 shift. Sonnax solenoid regulator valve kit 76948-14K prevents both sticking and leaking. Sonnax bore sizing tool 76948-BST2 is required to fit this valve to a closer tolerance.

• Hardcoat anodized aluminum valve combats premature wear
• Valve has extended spool lengths to provide more sealing area, preventing sticking and leakage
• A new spring is included to correctly regulate the extended spool valve
• O-Ringed end plug prevents shift solenoid oil pressure loss at the 1-2/2-3 shift valve.
• Annular grooves prevent side-loading that leads to premature wear and leakage
• Required use of the Sonnax bore sizing tool, 76948-BST2, removes the bore ridges that lead to valve stickiness and resizes the bore for optimum fit with the Sonnax valve
• Drop-in Zip Valve™ installs quickly and easily
