TKX Five Speed Single Overdrive Conversion up to 750hp

We put a New Tremec TKX in a 1966 Mustang.
The tunnel support was moved back 2-3/4″ then reattached to the floorplan & tunnel.
Our crossmember & mount were used on the TKX as you can see it maintains the angle requires and we have great clearances. We also have about 5/8″ space between the trans top & tunnel for driveline angle adjustment.
This is an added bonus to the already impressive rating of 600ft/lb of Torque & the new addition of triple cone synchros in the TKX gives you smooth shifting up to 8000 RPM.

For higher torque applications or you’re a ‘spirited driver,’ the TKX series five-speed is the latest offering from Tremec, check out these stats.

Rated for 600lb/ft of torque, will support shifting up to 8000rpm thanks to triple cone hybrid sintered synchronizers that the Tremec T56 Magnums have to make your driving experience the best.

The new end loading design makes for a stronger case with a new sleeker profile, eliminating top covers, that would have restricted room in the tunnel.

Above you can see the differences between the TKO & TKX cases

Much like the TKO the floor support has to be moved back about 2-3/4″ over the narrow section tail shaft housing to retain the stock drive angle.
The TKX offers a little more adjustment approx. 5/8″ at the tail shaft vertically for the driveline angle. Perfect for Pro-Streeters who love to tuck the rear suspension up into their ride.
This can be done by removing the factory spot welds and relocate the support back.
A great addition to the install is the MDL Crossmember item# MD-6566M-CMT5 and a new mount, this will maintain the transmission angle as well as providing superior clearance for exhaust and a locating arm for your emergency brake cable.

Cable clutch release
Since T-5, TKO, and Quick Time bell-housings are designed for a cable release, a matching fork is required. It is important to know the 3 or 4-speed mechanical release “clutch” can no longer be used as it will be too tall.
MDL offers cable release clutches for 10″ long pattern as well as the 10.4″ Metric bolt patterns.  The pressure plate lever height is lower and the release is faster.
To use the stock clutch pedal, MDL has engineered a cable kit that mates with the stock 65-66 Mustang pedal and comes complete with a firewall plate, custom double adjustable cable the is routed around the exhaust system.

 

Hydraulic clutch release –
MDL developed a complete line of hydraulic clutch release systems we call our LF (Light Foot) Series.
The master cylinder mounts on the firewall using our mechanical linkage that connects to the stock clutch pedal.  The linkage provides proper leverage and control while providing design flexibility.
Using the T-5 and cable fork, our external slave cylinder mounts to the back of the bell-housing fork opening, pushing the fork forward. Our hydraulic system gives you the most exhaust clearance while providing the softest pedal effort.
