  • Valve
  • Sleeve

  • Plug Used in Upper VB Only

Fits either of two locations

Complaint:

  • 4th Slip
  • 5th Slip
  • 6th Slip
  • Code 734, 735, 729
  • Kickdown shock
  • Kickdown slip

Cause:

Wear at different areas of the solenoid modulator valve lineup can result in high or low pressure and associated complaints.


Correction:

The Sonnax wear-resistant sleeve and valve correct circuit pressure loss and restore control over solenoid modulator valve function.

High and/or low pressure in the solenoid modulator circuits of Aisin AW TF-60SN units can cause DTCs and drivability complaints. Wear at the inboard end causes excessive feed pressure. This floods the solenoids and reduces reaction time, resulting in harsh shifting and high line pressure. Wear at outboard and mid-section reduces solenoid modulator pressure, which has the most effect on engagements and boost oil for line pressure rise.

  • The hard-coat anodized aluminum valve resists wear and has added annular grooves for better centering in the bore
  • The highly wear-resistant sleeve and lengthened front valve spool provide 75% more sealing contact area
  • This kit includes a new end plug and spring for proper calibration
NOTE:

F-15741-TL29PL required for reaming upper valve body #2.

You need this if...

Either a wet air test or a vacuum test in the locations shown result in leakage. A vacuum test must hold a minimum of 18".
