Monster Transmission’s original MonStar, Curt, shows how to convert from an original factory TH400 transmission to a 700R4 transmission.

Why would you want to go through this process?

Not only is the 700R4 a more durable automatic transmission, designed for heavy-duty usage, but it also provides better fuel mileage from the stronger overdrive and a lower gear ratio by a factor of 20%.

Curt goes over how to remove the original transmission from the vehicle, from the driveshaft and the torque converter to the unit itself.

From there, he uses one of Monster’s most popular products, the Master Conversion Package, to install the newly remanufactured transmission into the vehicle.

Items included in this kit include the actual 700R4 transmission, a performance torque converter, all the cables, bolts, and gears that are needed, a universal dust cover, and much much more.

Everything you need to know about upgrading your transmission can be seen in this step by step process with Curt. The process can be done by just about anyone with the right tools, making this less of a chore.
