As part of the TCI Maximizer Heavy-Duty RV Transmissions line, this package is built to support dependable power transfer while improving cooler flow and shift characteristics without the harsh feel of a racing-style transmission.
This kit is identified by Manufacturer’s Part Number 371402P1, Summit Racing Part Number TCI-371402P1, and UPC 788120032650.

The transmission is lockup compatible and features a 30-spline input, 3.06 first gear ratio, and OEM-style aluminum case with a natural finish.
The flexplate is not included, the transmission controller is not included, and the wiring harness is not included, so buyers should confirm all supporting components before installation.
Fitment and Application Details
