The MPT Stage 3.5 has all of the features found in our Stage 3 transmission, with the addition of a 35 spline oversized input shaft. This transmission is ideal in high torque applications that may need a stronger shaft than the factory sized 23 spline. It is the perfect candidate for a retrofit from 68RFE, and can be built with 29 spline output shaft by request.
- Transmission Installation cost (optional): $1000.00 (Effective 1/1/2023) – includes removal of old unit, hot flush of transmission cooler/lines and installation of MDP transmission with transmission fluid. Contact us to check scheduled installation lead time before ordering. To schedule an installation time, a non refundable deposit of $500.00 is required.
