Sonnax 3-4 Accumulator Control Valve Kit for E4OD, 4R100
The Ford E4OD and 4R100 transmissions frequently experience shifting issues due to problems with accumulator control valves. As the valve moves within the bore, wear ridges can form, leading to the valve over-stroking and hanging up on these ridges. This results in restricted oil flow to the associated clutch, causing soft shifts, gear loss, and burnt clutches. The Sonnax 3-4 accumulator control valve kit 36948-09K is designed to resolve these issues and deliver a firmer-than-OE shift quality.
Key Features:
- A step machined into the valve spool serves as an orifice, allowing full oil flow to the clutches when needed, preventing premature clutch failure.
- The reinforcement retaining clip connects to the OE clip to prevent over-stroking.
- Spring shims enable selective pressure adjustment to fine-tune shift quality.
- An annular groove helps center the valve within the bore, reducing future side-load wear.
- Drop-in Zip Valve™ parts ensure a quick and easy installation.
Note:
The Sonnax bore sizing tool 36948-12 (sold separately) is recommended for resizing the bore to prevent the new valve from hanging up or sticking. While recommended, the tool is not required for installation. See instructions for further details.
