• Hand-machined case clearances allow bolt-in installation without cutting the Tiger's transmission tunnel
• Gearing ratio (3.27, 1.98, 1.34, 1.00, 0.72) balances strong launches with relaxed highway cruising
• 10-spline input shaft (1-1/8 in. diameter) and 31-spline output shaft for added strength
• Compact end-loaded case design fits most transmission tunnels without floor modifications
• Ribbed 3-piece housing (main case, intermediate plate, rear extension) for structural stiffness
• Multi-cone synchronizers with sintered carbon/bronze hybrid rings for smooth high-RPM shifts
• ASTM 4615 special-grade steel gears and shafts with caged needle bearings in all gear positions
• 7.21-inch Ford input shaft length - bolts to Ford TKO/4-speed bellhousing pattern
• 0.670-inch pilot tip with 1.430-inch OD throwout bearing guide tube
• Built-in reverse light switch (left side) and cruise control safety switch (right side)
• Dual speedometer outputs: mechanical 7-tooth Ford gear (adaptable to GM) plus OSS two-wire analog sensor
• Gaskets at all mating surfaces eliminate fluid leaks
• High-performance short-throw billet aluminum shifter included
• MDL-modified shifter stub repositions to original equipment location for authentic Tiger cockpit layout
• MDL 2” left side shift front modification with a 1964-1967 Sunbeam Tiger modified offset stub - precise shifter placement without compromise

• MDL Exclusive - not available through TREMEC

Description

The Sunbeam Tiger's original Ford Toploader was tough for its time, but today's power levels demand more. The problem with dropping a modern 5-speed into a Tiger has always been fitment: wrong shifter position, tunnel clearance issues, and compromised packaging. MDL has solved all of it. This MDL-enhanced TREMEC TKX has been hand-machined at our Caldwell, Idaho facility to clear the Tiger's notoriously tight transmission tunnel without any cutting or floor modifications. The shifter is offset to place it in the Tiger's correct cockpit location, so you can use your original shift knob or ball and nobody will know there's a TKX underneath.

The TREMEC TKX delivers 600 lb-ft of torque capacity and shifts at 7,500 RPM - capabilities the Toploader simply cannot match. All gears and shafts are made from special grade steel (ASTM 4615) for increased torque carrying capacity, while tapered roller bearings on input, output, and counter shafts reduce noise and improve durability. The robust internal 3-rail shift system with steel shift forks delivers precision engagement under power. The close-ratio gearset (3.27 first, 0.72 overdrive) provides aggressive launches with highway-friendly cruising RPM - a genuine overdrive that the original 4-speed never offered.

TREMEC's end-loading design creates a slimmer case with fewer seams and greater structural rigidity than top-loaded alternatives. The 10-spline input shaft bolts directly to Ford Toploader-pattern bellhousings, maintaining your existing clutch system compatibility. Every unit is hand-prepared at MDL to ensure quality and precision - this is an upgraded transmission, not just a bolted-on shifter. Not available through TREMEC. MDL extends the manufacturer's warranty by an extra year with a 1-year grace period, plus provides lifetime technical support and industry-leading customer service. Made in the USA.
