The T5 5
Speed was originally manufactured by Borg Warner and is used in many applications.
Since 1982 this transmission has been used in Jeeps, Mustangs, Camaros,
Firebirds, S10 Blazers, Chevettes, Astro Vans, and even in Nissan Z cars.
It has seen many changes over the years and a complete history page will
be up shortly. We carry a complete line of parts and kits for all T5
configurations and have been doing so since 1982.
The Counter Gear Stabilzer was designed by us to make the low end of the
T5 World Class transmission more rigid. The factory rear bearing retainer
will stretch and distort under severe loads and the bearing race is ONLY
supported by the aluminum case. So whether you are pulling heavy RPM's
off the line or doing 170MPH in 5th gear these design flaws can cause
the counter gear to rock up and down on the taper of the counter gear
bearings. This rocking motion will elongate the rear bearing bore in the
case. It will also cause excessive clearance on 5th gear causing premature 5th failure.
Stabilzer Fact Sheet
race is supported by steel retainer and case
duty design allows for counter gear preload
eliminates counter gear rocking
excessive 5th gear backlash
rear bearing bore case wear
race Jaguars that we sponsor were breaking 5th gears approximately every
30 hours of race time. Since the addition of the Stabilzer breakage has
been eliminated completely. These cars hit speeds in excess of 150MPH
in 5th gear!
