SOLENOID SET (55-50SN) EARLY/LONG RE-MAN
# 74718K

Remanufactued SLS, SLT & SLU Solenoid Set Early with Long Solenoids

SOLENOID SET (55-50SN) EARLY/LONG RE-MAN

Early/Long design. Also fits AF23/33 and RE5F22A units.

Symptoms:

  • Flare shifts
  • Bang shifts
  • Shift concerns
  • Harsh Forward
  • Harsh Reverse
  • No lockup
  • Harsh TCC apply
  • Soft upshifts

Cause:
Internal component wear and sticking of the solenoid pintle cause critical SLT (line pressure) SLS (shift control pressure) and SLU (lock-up control flow) leaks and pressure concerns and spikes.

Correction:
Replace faulty OE and aftermarket solenoids with the 100% tested and calibrated Sonnax remanufactured solenoids to eliminate sticking solenoid complaints.


Warning:
Ensure correct style (early/short, early/long or late) of SLS/SLT solenoid based on connector direction and bracket design


Aisin AW 55-50SN and 55-51SN linear solenoids are used to control line rise (SLT), the converter clutch (SLU) and the oil flow rate and accumulation for the clutch circuits (SLS). The flow-to and function of these solenoids overlap, making diagnosis difficult. The solenoids are prone to sticking of the internal pintle, creating inconsistent movement of the solenoid valves. Shift complaints and pressure/flow related issues result.

The Remanufactured linear solenoid kit was developed with an exclusive Sonnax process that eliminates sticking solenoid problems. These solenoids are 100% leak tested and calibrated to OE specifications. Readjustment should not be required if the valve body leakage has been addressed and a relearn process completed.

  • Eliminates pintle sticking problem for proper solenoid valve action
  • 100% tested and calibrated
