The 6T30 is the GM 6-speed automatic fitted to Chevrolet Cruze, Malibu, Buick Excelle GT/XT, Cadillac, plus further applications in the same family. This page covers the solenoid kit for that platform, supplied by Guangzhou Meishun (TRANSMESUN) — a CE-certified remanufacturing factory in Huadu, Guangzhou, with 20 years in the transmission trade.
Extremely well documented: the 3-5-R wave plate, pressure-regulator bore wear and the 1-2-3-4 clutch are the classic failure chain — updated wave plates and bushings exist. That failure chain is exactly what our process is built around: the part is inspected against the platform's documented wear points. Response and flow bench-checked per unit before packing. Every order is verified against your transmission code before anything ships.
