Overview
The ZF 4681.101.002 TRANSMISSION HOUSING is the central structural core of the BP210 and BP230 series transmissions. This OEM genuine part encloses the planetary gear sets, valve body, and torque converter assembly, providing precise alignment and protection from contaminants. As the main casing, it absorbs torsional loads and maintains oil pressure integrity throughout the drivetrain. The SKU 4681.101.002 is engineered to ZF’s exacting tolerances, ensuring a seamless fit with internal components like the 4681201007: HOUS.FRONT SECT and the 4681201008: HOUSING REAR PART to form a complete, leak-free assembly.
Symptoms of Failure
When the ZF 4681.101.002 transmission housing deteriorates, operators may notice these specific failure indicators:
- Persistent oil leaks at the bell housing seam: Cracks or warping in the housing cause fluid to escape, leading to low transmission fluid levels and erratic shifting.
- Gear slipping under heavy load: A compromised housing can misalign the 4681298001: CASE, reducing clutch pack engagement and causing power loss.
- Excessive drivetrain vibration: Structural fatigue in the housing allows the input shaft to wobble, producing audible humming or grinding noises during acceleration.
- Contaminated transmission fluid: Housing cracks permit dirt and moisture ingress, accelerating wear on internal bearings and seals.

Frequently Asked Questions
Q: Can the ZF 4681.101.002 housing be repaired if cracked?
A: Minor cracks can sometimes be welded by a specialist, but ZF recommends replacement to maintain structural integrity. A repaired housing may not meet OEM torque specs, risking future failure.
Q: What torque should I use for the housing bolts?
A: For the M10 cap screws (part 0636100801), use 45 Nm. For the M12 bolts (0636100803), use 70 Nm. Always tighten in a cross pattern to avoid warping the housing.
Q: Does this housing include the oil feed line?
A: No, the 4681.101.002 is the main casing only. The oil feed line is a separate component (part 0750100162) that must be ordered individually.
