TCC Apply Valve with Teflon Seal For Non PWM Pumps

TCC APPLY VALVE KIT 4L60/4L60E N/PWM

Symptoms:

  • No lockup
  • Falls out of lockup when hot
  • Fluid blown out fill tube
  • Lockup immediately after 2nd gear
  • 1-2, 2-3, 4-5 Flares

Cause:
Excessive pump bore-to-valve clearance allows TCC signal oil to leak past the spool, preventing lockup or causing lockup to disengage when hot. Additionally, converter feed can leak past the excessive clearance, combine with signal oil and cause premature lockup.

Correction:
These improved TCC apply valves with PTFE seals will eliminate bore cross leakage.


Warning:
This part only fits non-PWM units, and mismatching PWM and non-PWM valves will cause rapid converter failure.

  • Hardened steel valve matches OE material
  • PTFE seal eliminates cross leaking of converter signal oil and converter feed oil
