Valve 1-2 & Reverse Boost 4T60E
- Valve

Fits either of 2 locations
The continuous stroking of the 1-2 (forward) and reverse servo boost valves wear away at the valve bore, creating excess clearance and reduced apply pressures. This can lead to 1-2 band slippage, delayed engagements, 1-2 shift flares, and decreased reverse pressure. Sonnax has developed an oversized valve 84754-40K that will restore the hydraulic integrity and more than doubles the valve-to-bore contact area to prevent leakage.
Symptoms:
1-2 Band burned
1-2 Flare Delayed engagement
Low Reverse pressure
Cause:
These complaints may be caused by the continuous reciprocation of the 1-2 (forward) and reverse servo boost valves wearing the valve body bores.
Correction:
This oversized, hard-coat anodized aluminum valve restores hydraulic integrity, and has increased valve-to-bore contact to prevent leakage. This valve requires the use of a Sonnax reaming tool kit.
NOTE: This kit only contains one valve. If both bores need to be repaired, two kits are required.
Required tools:
Reamerkit 4T60E, 4T65E 1-2/Rev: 84754-TL2
