Product Details

ATP Parts B-152 is engineered for transmission maintenance where fluid cleanliness matters. Over time, normal wear can introduce debris into the transmission fluid, and a clogged filter can restrict flow and contribute to drivability and shifting concerns.

This part cross-references Bosch 18026 for the same application.

Common Issues Addressed

• Restricted transmission fluid flow
• Debris buildup in the transmission filter
• Valve body contamination
• Harsh or inconsistent shifting related to service neglect
• Preventive maintenance on higher-mileage transmissions

Installation Notes and Tips

Install B-152 during a transmission service when the pan is removed and the fluid is being replaced. Confirm the vehicle application by year and model before ordering, since coverage includes multiple BMW chassis and a Cadillac Catera application. Clean the transmission pan and inspect the fluid condition before reassembly. For fitment, this part fits 1992-1999 BMW 318i, 1993-1995 BMW 325i, 1996-2000 BMW Z3, and 1997-2001 Cadillac Catera.
