Product Description
4R70E 4R70W 4R75E 4R75W AODE Oversized Manual Valve Kit by Sonnax (1992- Later)
Part No. 76948-46
Fits '92-later units.
Tooling:
Many 4R70E, 4R70W, 4R75E, 4R75W and AODE units have a loose manual valve or worn bore that creates a significant line pressure leak. Loss of line pressure results in delayed engagements, burnt clutches and bands. OE manual valves have been observed continuously rotating in the bore due to forces caused by the flow of fluid. Constant rotation of the valve contributes to premature wear of the valve bore. The Sonnax tool kit F-76948-TL46 reconditions the bore to accept the Sonnax oversized manual valve kit 76948-46. This manual valve eliminates the constant axial rotation and its precision machining tightly controls clearances to minimize line pressure leaks.
- Eliminates line pressure losses to cross leaks
- Establishes tight clearances between manual valve spools and bore lands
- Ends flow-induced axial rotation of manual valve
Note:
Upgrades '92-'98 valve bodies to '99-later specifications. The '99-later units have a quicker direct clutch exhaust on 4-2 manual downshift.
