Product Overview
A rising whine that follows vehicle speed, rough pulley rotation, or metal found during teardown can point to bearing damage inside the CVT. This kit is for transmission rebuilders who have identified the K114 unit and are replacing the pulley-support bearings during a proper overhaul.
Vehicle listings are only a starting point. Toyota and Lexus used more than one transmission across the same model and year, so the K114 code on the transmission identification must be confirmed before purchase.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model names and year ranges are a starting point. Match the original reference number, configuration, connections, mounting points, and product-specific details before ordering.
Frequently Asked Questions
Q: Can I order by vehicle model alone? A: No. Confirm the transmission code because the same vehicle family may use a different CVT.
Q: Will bearings cure every CVT whine? A: No. Pulley surfaces, gears, pump, differential, and other bearings can also make noise and must be inspected.
Q: Is this a complete transmission rebuild kit? A: No. It is a four-piece pulley bearing set; seals, filters, fluid, and other hard parts are separate.
