Product Description

The Mishimoto MMTC-RPTR-TBV Thermal Bypass Valve Kit is a direct-replacement transmission fluid bypass valve for the 2017-2021 Ford F-150 Raptor equipped with the 3.5L EcoBoost V6 and 10R80 automatic transmission. Designed to improve transmission fluid flow to the cooler, this thermal bypass valve uses a fully serviceable thermostat that opens earlier than stock for improved operating temperatures, then offers a bypass option for constant cooler flow in high-load or hot-climate situations.

Constructed from durable CNC-machined billet aluminum with integrated heat-sink fins, the valve maintains strength and corrosion resistance while dissipating heat more effectively than the factory unit. Installation is straightforward with included hardware and seals, and the unit works with the stock cooling lines without modifications. Backed by Mishimoto's Lifetime Warranty, this kit helps protect your Raptor's transmission under demanding highway, off-road, or towing conditions.
