Overview
The ZF 6073.324.067 DRIVE PROGRAM is a critical OEM genuine component engineered specifically for the BP 230 Series transmission. This precision-machined assembly governs the hydraulic flow and gear selection logic within the transmission control unit. Positioned directly between the main valve body and the TRANSMISSION HOUSING, it acts as the central command interface for clutch pack engagement and torque converter lock-up. The SKU 6073.324.067 is manufactured to ZF’s exacting tolerances, ensuring seamless integration with the HOUS.FRONT SECT and the HOUSING REAR PART to maintain optimal hydraulic pressure integrity.
Symptoms of Failure
- Erratic gear hunting or delayed engagement: A worn drive program often causes the transmission to hesitate before shifting or to randomly skip gears, especially under load.
- Hydraulic fluid seepage at the valve body interface: Deteriorated sealing surfaces on the 6073.324.067 can lead to visible oil leaks around the CASE mating area, reducing system pressure.
- Harsh or clunking shifts: When the drive program loses its calibrated flow paths, shift quality degrades from smooth transitions to jarring engagements.
- Intermittent loss of drive in forward gears: A failing unit may cause the transmission to momentarily lose power delivery, particularly during low-speed maneuvers.

Compatibility
This OEM genuine drive program is designed for the BP 230 Series transmission family. It is directly compatible with ZF models including the WG180, WG200, and WG210 when configured with the BP 230 valve body architecture. The 6073.324.067 also integrates with earlier iterations of the 4HP and 5HP series that share the BP 230 hydraulic platform. Always verify the CASE casting number and the TRANSMISSION HOUSING revision before installation to ensure proper fitment.

Frequently Asked Questions
Q: How do I know if the 6073.324.067 drive program is failing?
A: Common indicators include erratic shifting, hydraulic fluid leaks near the valve body, and a noticeable delay when moving from Park to Drive. If you observe these symptoms, inspect the drive program and the surrounding CASE for wear.
Q: Can this part be installed without replacing the transmission housing?
A: Yes, the 6073.324.067 is designed as a standalone serviceable component. However, we recommend inspecting the TRANSMISSION HOUSING and the HOUSING REAR PART for cracks or scoring during the repair.
Q: What torque specifications apply to the cap screws securing this drive program?
A: Use the CAP SCREW (0636100801) torqued to 25 Nm and the CAP SCREW (0636100803) torqued to 45 Nm for proper sealing and alignment.
