Starting with the T5z, Modern Driveline will install our unique “Front Shift/Rear” position tail housing. Locating the shifter 13.25” from the back of the bell housing. This transmission is great for street use and stock to moderate horsepower engines.

We have many shift lever options to accommodate whatever application you need.


 Next is the TKO transmission. Modern Driveline will install the “Mid Shift Kit” locating the shifter about 13.39” from the back of the bell housing. Depending on the engine used, Modern Driveline will use an offset shifter for correct shifter positioning. The TKO is a robust transmission and is capable of 600 FT/LB of torque and is great for small and big block engines for street and some strip use.

Then we have the T56 six-speed for higher horsepower and torque for the higher RPM Mod motors. Modern Driveline will install our Front shift Kit locating the shifter about 13.06” from the back of the bell housing. Depending on the engine, used, Modern Driveline will use an offset shifter for correct shifter positioning.

Once the transmission has been selected, Modern Driveline personnel will work with you to determine the best way to adapt a transmission to your Truck. If your truck is a manual, to begin with, you will be able to reuse the existing OEM bell housing using an adapter, your flywheel, and mechanical clutch release in most cases. Or with some FE housings and TKO transmissions, Modern Driveline can modify the input shaft for FE bell housings.

If your truck is equipped with an automatic transmission, we will start by selecting the correct bell housing, flywheel, and clutch release.

Clutch selection is the next critical step. Modern Driveline will select one of our inhouse, handmade clutches that is matched to your horsepower and use up to 600 Horsepower. Beyond 600 Horsepower or strip use, Modern Driveline will recommend and provide either a Tilton twin disk clutch and Chromoly flywheel or the Mcleod twin disk clutch.

If your truck is a 4X4 and the transfer case is a separate unit, MDL can use a special Chromoly 1310 yoke with removable caps between the transmission and transfer case and you can have the shaft shortened at a local shop.

With all Ford F-series trucks, you will need to modify the existing cross member, or make a crossmember to support the transmission.

We will supply you with a slip yoke rated for your horsepower and use. Or we can provide a steel, aluminum, or carbon fiber driveshaft as needed.

Modern Driveline has figured out all the details for Ford F -Series Truck conversions for small block, big block, and Mod motors.

Below we highlight the different options there are for the different year F-Series truck. We even have something for the smaller Ranger pickups.
From Flathead V8 to the latest Ford Coyote engine and everything in between. 

T5 Five Speed Single Overdrive solution.

For trucks making under 450hp, the T5 Front shift five-speed is a great platform to look at.
With is small case it fits in early truck frame nicely without cutting the floor open.  Since most trucks are equipped with a bench seat, the shifter located needs to be brought forward.
Well MDL can do that with our front shift T5.  We start with a T5 and install our Front shift tail shaft housing that moves the shifter forward about 8″.  With our large selection of shift levers, we can find one that will make it easy to shift and look right.  If one has a shift lever built into the stock transmission, with a few mods, the stock lever can be transferred over to the five-speed and bolt-on retaining a stock look.   

The Ford T5 has a unique transmission bolt pattern that will not allow it to be bolt directly to a stock 3 or 4-speed bellhousing.
This is where our T5 adapter plates come in.
Making up for the difference in input shaft length and pattern, our adapter plate interlocks into the stock bellhousing and allow for the T5 to slip in behind the plate. 

Beginning in 1930 through early 50’s Ford trucks with 59A Flathead or even the later 8AB model our MD-401-2109 flathead adapter “bellhousing” converts to a Ford T5 or TKO series five-speed.
The bellhousing comes with a clutch release fork and cross shaft to use the stock clutch linkage.
if your truck is equipped with a Hogshead bellhousing with six transmission mounting bolts.
Our MD-401-2114 plate is the answer.

Starting in mid 50’s Ford install a new Y-block V8 with either 3 or four-speed transmissions that had two different transmission bolt patterns.  Regardless of which bellhousing you have, MDL had the T5 adapter plate.  Since the Y-block truck bellhousing are deeper than the car y-blocks, a longer 94-04 Mustang 8″ T5 input shaft is needed to fit the adapter plates.
Our Y-block front shift T5 MD-552-0251-YFS-F has the longer input shaft with a 2.95:1 first gear ratio and .63:1 OD.  Optional .73:1 OD available.

Ford Y-Block T5 Front shift with adapter Kit

When looking at a small block V8 powered trucks installing a T5 five-speed is easy.  Five bolt 260/289 with the narrow transmissions use a MD-401-2101 adapter T5 adapter plate or the use of a QuickTime bellhousing T5 conversion bellhousing MD-401-6067.  Six bolts 289/302/5.0L can use the stock bellhousing with an adapter plate or a T5 aluminum bellhousing.  Choices of clutch linkage can be mechanical, cable, or hydraulic release.

Ford Range V8 conversions

When performing a V8 conversion a Ranger, our front shift T5 is the way to go with a compact size.  The front shift T5 uses the stock shifter location.  If the stock shift lever with the built-in boot is modified, it can be bolted the T5 shifter. The stock hydraulic clutch master can be coupled to our external LF series slave cylinder using the T-5 bellhousing.
The stock master cylinder output fitting is removed, and a conversion fitting is provided connecting to the AN4 braided line.


MDL Adapter Plates and flathead adapter bellhousings 

T5 Bellhousings 

MDL solved the issue of shift position with our line of offset shifters to move the lever up to 2″ from shifter pivot points.  With the Mustang T-5 long shift box, we can offer two-shift pivot locations front and rear sockets.  Couple this with an up to 2″ offset shifter stub front/back and left/right, a range of 5″ can be achieved from standard Mustang tail-housing.  Cars and trucks of the ’20s and later, the shifter needs to be a lot further forward to clear the seat.  MDL tooled up and build a front shift tail-shaft housing that bolts to the WC T-5z.  We used the same shift box of the Mustang housing to give us the same flexible 5″ range.  Measuring from the rear block surface to the shift lever base, a range of 16.5″-28.3″ is available.
We are not done yet; we offer a complete line of shift lever handles to further fine-tune the shift knob position to make your Hotrod comfortable and fun to drive

TKX Five Speed Single Overdrive Solution.

Serving up to 600ft/lbs or about 800hp tire melting torque capacity and up to 8000RPM shifts.
The TKX has the same transmission bolt pattern as a wide pattern Toploader.

With the short shift kits, we offer, it can bolt bolted directly to the 3 or 4-speed bellhousing or scatter shield.
If you have a Ford narrow pattern bell-housing and wish to keep it, our
MD-401-2111 adapter plate solves this problem.  Don’t have a bellhousing?  For small-block Ford V8, we offer an aluminum TKX bell-housing that the TKX’s bolt directly too.  If your needs are requiring a scatter shield, we offer a complete line of QuickTime scatter shields for just about every Ford motor ever produced.  TKX Bellhousings 

TKX offers up no less than three shift-socket positions to meet your need.
Out of the box, the TKX has the shifter at the rearmost position at 19.52″ from where the front of the transmission where it bolts to the bell.
With just the turn of a wrench, the six-mounting bolt can be moved to turn the shifter around placing the shift stub at 16.57″.
With the MDL offset shifters stub, we can place the lever up to 2″ from each socket position.
The most forward position available Tremec calls a mid-position as the front shift position on the top cover is no longer available.
MDL offers a Mid shift kit that replaces the mid-top cover.  A replacement lug is required and is part of our kit.  The mid-shift kit also includes a rear position cover.
When installing a mid-shift kit, the rear rail is disconnected make the cruise control shut-off switch disabled.  


TKX comes in different gear ratios.

The TKX is the same as the old TKO with a 3.27:1 first but has a new .72:1 OD.
This ratio is great for those with trucks or has a rear-end ratio that is on the taller side (3.0-3.25:1 assuming 26-27″ tires) with no plans to change the ring and pinion.

The TKX can also be equipped with a 2.87:1 first gear and two different overdrive ratios a .68:1 OR .81:1.
Depending on the engine setup, most folks are looking to compensate for the 3.73-4.11:1 axle ratio and want a 36% overdrive or .68:1 OD.
If the motor cannot cruise at such a reduced rpm, a .81:1 ratio of 20% overdrive is available.

T-56 Magnum Six-speed Double Overdrive

The Tremec Magnum six-speed is the big dog in the family overdrive transmissions.  Built on the OE TR6060 platform, the Magnum was designed for the aftermarket with the same flexible features found in the TKX.  The Magnum is a double overdrive transmission that can be rated for 700ft/lbs. or about 1000hp.  Available in two gear ratios of either a 2.97 or 2.66:1 first with either .80/.63:1 or a .74/.50:1 overdrive 5th and 6th gears.  Magnum is the largest of the transmission due to it brute strength rate.  With a shift point of 7,800rpm, the Magnum is a great pairing for high revving engines like the 5.0L Coyote.  Mounting a Magnum six-speed is easy with a complete line of aluminum and steel bell-housings offered.   We recommend a hydraulic clutch release for a light pedal effort and maximum clearance.
