Description

Converting your Y-Block Ford from a three-speed or automatic to a modern five-speed overdrive? This complete TREMEC T-5 package delivers everything you need in one coordinated system - no chasing down individual components or hoping parts work together. The T-5 handles 300 lb-ft of torque while providing a deep 0.63:1 overdrive that dramatically reduces highway RPM and improves fuel economy. At only 75 lbs. dry, it's TREMEC's most compact transmission and fits where larger units simply cannot.

The engineering centerpiece is the QuickTime RM-8055 bellhousing connecting your Y-Block to the T-5. Built from high-grade steel that work-hardens to over 80,000 PSI - more than twice the strength of other steel bellhousings - this isn't your typical stamped housing. QuickTime's patented spin-forming process creates the most dimensionally stable and accurate bellhousings available, eliminating the runout issues that plague lesser units. This precision matters: improper bellhousing alignment destroys input shafts, pilot bushings, and clutches. The engine and transmission stay in perfect alignment through the entire RPM range, eliminating accelerated drivetrain wear caused by bellhousing flex.

The 2.95:1 first gear provides strong take-off performance, while the well-spaced ratios of 1.94, 1.34, and 1.00:1 through the midrange keep your Y-Block in its powerband during spirited driving. The 0.63:1 fifth gear drops cruising RPM significantly, reducing engine temperatures and noise while improving fuel economy. The transmission uses a 10-spline input shaft and 28-spline output shaft, requiring 2.75 quarts of Dexron III ATF. Multiple custom shifter positions let you dial in the perfect shift location for your build.

This guided package system walks you through selecting every component - transmission, bellhousing, flywheel, clutch, shifter, driveshaft yoke, and speedometer gear - ensuring complete compatibility. MDL has developed and selected the best components in the industry for Y-Block conversions. If you have questions at any point, MDL's transmission specialists can provide concierge service to help you make the right selections for your project and budget.
