The TR-4050 provides an essential option for a market that has been missing.
“For years, MDL has had to turn away 4wd married transfer case vehicle owners because there wasn’t a good transmission solution available.
The TKO/T56/Magnum transmissions have no provisions to mount a 4wd transfer case. Not to mention the gearing is not right for 4WD vehicles.
Classic and modern 4WD transmissions have low gearing, ranging from 4:1 to as low as 7:1. This lower gearing is preferred for off-road use
where you want to crawl, climb, or go through obstacles.
The existing 2WD models simply do not offer the low gearing needed for off-road use and larger-diameter tires.
The TR-4050’s combination of 6.16 low gear and .76 overdrive (24% rpm reduction) is a win/win for the 4wd market.
The TR-4050 can be mated to a variety of different O.E. transfer cases
The TR-4050 will have parts and warranty support for quite some time unlike the popular NV4500, which has been out of production since 2007.
The TR-4050 is a proven design that has been in production since the early 1990s.
A rugged, die-cast, aluminum-alloy case forms the foundation.
The gears have a high-contact, constant-mesh, helical design for maximum strength It has a torque-handling capacity of up to 425 lb-ft on a working GCVW of more than 15,000 pounds.
For increased internal stability under load, the input, main, and counter shafts feature tapered roller bearings.
A counter-shaft–mounted 5th gear synchronizer improves noise, vibration, and harshness in overdrive.
With gear ratios of:
6.16 first, 3.11-second gear, 1.71 third gear, 1.00 fourth gear, & .76 overdrive fifth gear.
The TR-4050 is more capable than either
the NV4500 or NP430 transmissions at off-road use,
while still being capable of highway and everyday driving.
Single- and double-cone synchronizers give the driver silky-smooth shifts.
If PTO capability is needed, the TR-4050 has a standard, right-hand, six-bolt PTO hookup.
The TR-4050 can be mated to a multitude of engines:
Cummins 4BT, 6BT, 5.0, and R2.8
small-block Ford Windsor and Coyote
small- and big-block Chevy and LS Series
small-block Mopar and Gen III Hemi.
It’s an ideal replacement for the AX15, NV3500, NV3550, and NV4500 5-speeds,
as well as NP435A, NP435L, NP435D, NP435E, T18, T19, T98, SM420, and SM465 4-speeds.
