TREMEC\u2019s engineering team has been burning the midnight oil developing a groundbreaking five-speed transmission for the new millennium.
The all-new TKX five-speed manual transmission leaves the gate with a terrific compact design, increased 600 ft\/lb torque capacity, and buttery smooth shifts at high (8,000!) rpm, making it a great choice for your 1965-04 Mustang project.
The TKX is, without question, a high-performance five-speed for the Mustang generations.<\/p>\n

But first, some background.\u00a0 TREMEC\u2019s best engineers set forth a number of objectives in the TKX\u2019s bones. They wanted a vastly improved design based on the TKO transmission\u2014including fierce durability and brute strength in a race-proven package. They wanted it to fit a wide range of vehicles and with no floor pan modifications.\u00a0 TREMEC\u2019s marketing and engineering people wanted a box that would go right in without having to cut the transmission tunnel. They conceived a compact, end-loaded<\/strong> design to make the transmission as nearly compact as the T-5 transmission. \u00a0What\u2019s more, by having an efficient overdrive unit, engine wear and fuel consumption would be significantly better than straight-drive three-speed and four-speed transmissions found in vintage muscle cars.<\/p>\n

 <\/p>\n

Smooth Shifts<\/strong><\/span><\/p>\n

The efficient TKX delivers smooth shifts at high rpm via multi-cone, high-performance, strut-type synchronizers, and hybrid (sintered bronze and carbon) synchronizer rings. Designing in double cones at all gear changes enables power shifts as well as reduced shift effort.\u00a0 You get to glide through the cogs with virtually no effort. TREMEC has designed in an interlock, which prevents erred two-gear shifts and a lot of unpleasant noise and damage. Shift travel is a minute 8.75mm through the gears. A built-in inhibitor system eliminates the risk of accidentally selecting reverse gear as you downshift from fifth to fourth gear. The TKX\u2019s gears have been case-hardened and shot-peened for strength.<\/p>\n

 <\/p>\n

Less \u201cNVH\u201d<\/strong><\/span><\/p>\n

As vehicle quiet has become more important, noise, vibration, and harshness (NVH) have become TREMEC\u2019s focus. TREMEC engineers designed a ribbed, three-piece aluminum main case, intermediate plate, and extension housing for structural stiffness, which greatly contributed to reduced NVH.\u00a0 Their close attention to detail eliminated the potential for leaks. Expect to see gaskets at all flanges. Improved durability continues with oversized gear widths, which can now handle high-load shifts. There are caged needle bearings in all gear positions.<\/p>\n

A ball detent is on each shift rail to improve shift feel and provide precise, smooth shifting. Simulation software optimized the size and configuration of the chamfers in the gates and selector finger, so there\u2019s no sticking between gates and shifting stays true in both normal and aggressive driving.<\/p>\n

We\u2019re thrilled with the space-saving, smooth shifting, brute tested tough TREMEC TKX transmission from Modern Driveline.
From the people who invented five-speed conversion kits for an American icon comes a dreamy five-speed transmission Mustang enthusiast have been waiting for.
It is priced competitively compared with the proven TKO.\u00a0 What\u2019s more, it will fit your Mustang regardless of generation.<\/p>\n

The legendary TREMEC TKO five-speed (left) with 500 and 600 ft\/lb of torque capacity set the standard for brute strength in high-performance overdrive transmissions.
The all-new TREMEC TKX (right) introduces a whole new standard for five-speed performance.
It fits in all the same locations as the T-5 and TKO\u2014only it fits better.<\/em><\/p>\n

From behind, you can see the sweet compact fit of the TKX, with the shifter located where it comes right up through the transmission tunnel of 1965-04 Mustangs.
When you take delivery of your TKX from Modern Driveline, you will be amazed at the fit.<\/em><\/p>\n

 <\/p>\n

\"\"
The Modern Driveline TKX has all of the same electrical connections as the TKO and T-5 transmissions.
There are also three shifter locations for a wide variety of applications.
The TKX will work with both electric and cable-driven speedometers.
That\u2019s the back-up light switch screwed into the main case.<\/em><\/p>\n

The TKX has a sexy belly that\u2019s also streamlined to where it is undetectable as you look across a Mustang\u2019s underpinnings.
It fits right onto the TKO\u2019s transmission cross member.<\/em><\/p>\n
