PART # 135790K
Fits 6T30 and 6T40 Series
Symptoms:
- No 4th
- No 5th
- No 6th
- Low clutch oil pressure
- Harsh shifts
- Flare shifts
Cause:
Excess actuator feed limit (AFL) bore wear allows pressure loss that leads to driveability concerns.

Correction:
Recover hydraulic control and renew shift performance by installing drop-in Sonnax sleeved actuator feed limit valve kit.

The function of the actuator feed limit (AFL) valve is to provide regulated pressure to shift solenoids. Wear in the AFL bore causes low clutch pressure and results in transmission slips/harsh shifts. This eventually leads to a loss of 4th through 6th Gears, and finally the loss of transmission function.
