Product Description
Sonnax part number: 54754-02
4L30E TCC Regulator Valve Sleeve
2000-UP Units with PWM Style Pumps
No tooling required
GM 4L30-E TCC regulator valve sleeve is prone to warping because of the large slots on both sides of the sleeve. Once warped, the valve binds and gets stuck in one position or leads to excessive bore wear and circuit leaks. Sonnax TCC regulator valve sleeve 54754-02 has reinforcement ribs for added stability and is made from wear-resistant aluminum alloy material.
- Reinforcement ribs added for sleeve stability
- Made of wear-resistant aluminum alloy material
- Drop-in Zip Valve™ installs quickly and easily
Symptoms
- Code 894, 1870
- TCC slip
Cause
The OE sleeve warps due to large slots, causing the valve to bind up, or leakage occurs due to sleeve wear, resulting in loss of any pressure.
Correction
Replace the OE sleeve with a Sonnax drop-in TCC regulator valve sleeve, which provides added stability and better wear resistance.
