Twinspark 4 CYL

This Twinspark 4 CYL is a used automatic transmission, removed from a running donor vehicle and inspected by our technicians rather than shipped unchecked. Fluid condition, case integrity, and shift feel are all reviewed prior to listing, giving you a documented starting point instead of a total unknown.

Key Specifications: Every internal component and the housing itself are the original factory design for this BMW application, no reproduction parts. Transmission type: Manual or Automatic (verify variant at time of purchase). Gear count varies by production year and market for the Twinspark 4 CYL; check the tag on the housing or send us your VIN and we will confirm before you order. Compatible engine(s): TWINSPARK engine variants. The Twinspark 4 CYL was offered across more than one drivetrain layout, so double-check whether your chassis is front-, rear-, or four-wheel drive before you place the order.

Performance Characteristics: As an automatic unit, smooth shift quality depends heavily on fluid condition and the health of the valve body and solenoids, so a fluid and filter service at installation is worth doing even on a freshly tested used unit.

Common Applications: Expect this unit to fit BMW vehicles that were factory-paired with the TWINSPARK driveline described above. Because the same casting is often reused across multiple model years with small internal or electronic revisions, we recommend confirming the exact spline count and control variant against your vehicle, or simply sending your VIN so our team can verify fitment ahead of time.
