Boostvalve A750,A760,A960,AB60
- Inner Boost Valve
- Outer Boost Valve
- Sleeve
- Boost sleeve is manufactured from highly wear-resistant billet aluminum to prevent the excessive wear exhibited by the cast OE sleeve
- Restores proper line rise
Symptoms: - Clutch & band failures
- Harsh shifts
- High line pressure
- High line pressure in Reverse
- Low converter pressure
- Low line pressure
- Low line rise in Drive
- Overheating
- Soft shifts
Cause:
These complaints can be caused by severe wear of the boost valve sleeve, allowing EPC, cutback and reverse oil leakage.
Correction:
This Sonnax boost valve kit features upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control.

End plug kit A750,A760,A960,AB60
- Part #
- 147741-30K
- Reference #
- 78037A
- Extra information
- Symptoms: Various concerns depending on location of leaking end plug Pressure loss Cause: Worn, eroded end plugs allow loss of critical hydraulic pressure. Correction: These Sonnax O-ringed end plugs restore correct circuit pressures. The O-ring provides additional sealing to reduce hydraulic losses at critical circuits. Part No. 147741-30K •End Plug, 9mm •O-Rings, Small (2) 1 Extra •End Plugs, 11mm (10) •End Plugs, 12mm (2) •O-Rings, Medium (19) 7 extra •End Plug, 14mm •O-Rings, Large (2) 1 extra •Installation Screw The primary design function of the OE end plug is to prevent critical pressure loss by capping the bore. OE end plugs rely entirely on small clearances between the end plug and bore to confine hydraulic fluid under fluctuating pressure. End plugs are often tasked with a secondary role functioning as a spring stop or valve stop. The repetitious and varying actions of fluid pressure, spring motion and valve impact cause wear at the end plug and bore mating surface and can distort the shape of the end plug.High pressure fluid leaking through the clearance gap can, with time, erode the surface material of both end plug and bore. Eventually the cumulative loss of hydraulic integrity leads to low pressure in critical circuits. Complaints vary depending on the location of the worn end plug, but are always related to pressure losses. Sonnax O-ringed end plug kit 147741-30K replaces worn, distorted or eroded end plugs in Toyota/Lexus A760, A960 and AB60 series units. The Sonnax end plugs have small clearances to mechanically block the bore and increase effectiveness. The O-ring seal reduces leakage further by blocking off worn areas of the bore which the new end plug alone could not seal. •No special tools required •Minimal end plug-to-bore clearance with added O-ring for positive seal

L/U ctrl plunger OS A750 / A760E / A960
- Plunger Valve
- Sleeve
Toyota/Lexus A750, A760 and A960 series transmissions can have complaints associated with a worn plunger valve and sleeve which includes harsh 2-3 and harsh coast downshifts. This is due to the converter clutch remaining applied. When the plunger valve and sleeve wear, this can delay TCC apply, the vehicle RPM may surge or set gear ratio codes due to high slip rates. Installing the Sonnax drop-in lockup control plunger valve and sleeve kit 147741-37K can restore correct lube pressure and valve control timing when bore wear at the lockup clutch control valve is not an issue.
- Restores OE function
- Drop-in components
- No tools or reaming required
Symptoms: - Harsh downshifts
- Overheated fluid
- RPM surge on coast
- TCC apply & release concerns
- TCC codes
Cause:
Wear at the plunger/sleeve assembly results in the converter remaining applied and transferring shift shock. Loss of lube pressure and control timing also results in RPM fluctuation.
Correction:
The Sonnax lockup control plunger valve and sleeve kit corrects lost lube pressure and control timing issues caused by a worn OE plunger valve and sleeve.
