street and towing to full race, BD Builds Them Best!
transmission was only designed to handle the torque
and horsepower the stock engine delivers, and in the
case of some Dodge models, even the stock torque can
present a challenge. So when you start adding power
modules, turbo upgrades and other bolt-ons, it’s
only a matter of time before the transmission wears
out and eventually fails.
BD transmissions are built specifically to handle the
high torque loads of diesel engines at our state-of-the-art
transmission facility. We re-program the valve body
for higher line pressure, and add heavy-duty clutches
with up to 25% more material than stock. The stock thrust
washers, which disintegrate and leave metal filings
in your transmission, are replaced with roller Torrington
bearings. We can upgrade early 47RE transmissions with
more rugged 48RE components, even add billet steel input
shafts for extreme applications.
each transmission is a NEW DESIGN valve body that achieves
up to 80% higher clutch apply pressures over the stock unit
and up to 50% over the competitors with the increase starting
at much lower engine rpm’s and at lighter throttle pedal
position movement. Light throttle shift firmness is also maintained
at these higher apply pressures.
packages also include a BD rigid aluminum heavy duty transmission
pans which adds extra oil capacity and reduces case flex,
plus, includes a BD auxiliary full flow filter kit for extra
is dyno-tested to make sure it functions properly in all gears
before it is shipped to you in one of our containers.
options to consider when replacing your transmission are to
mate the BD transmission with one of our Torque Converters
and Flex Plates for added performance and strength. Call for
