- The many ways to
a 5 speed conversion
a five speed transmission into an early Mustang,
Falcon, Cougar, 2x4 truck, hotrod, Cobra or almost
anything, could not be any easier these days. Many
of the five speed transmissions found in late models
can be used in a swap with little modification. There are
several good five speed transmissions to choose
from. The Borg Warner/TREMEC T5, TREMEC 3550,
and TKO, and the new TKO 500, 600. T-45 transmissions found in
1996-99 4.6L Mustangs are limited to just
that 4.6L as the bolt pattern is completely
different than that of Windsor blocks. 4.6L motors
are not limited to the T-45 as there is a bell to
install a TREMEC behind a 4.6L mod motor. More on
that later. All of the transmissions offer a
5th gear over-drive to reduce engine rpm and for
improved mileage while weighting less than their
automatic or four speed counterparts.
There are three ways to approach a five speed
an early 3 or 4 speed bell housing with an
adapter plate allows an easy T5 swap,
a late T5 or TREMEC TKO bell housing, which allows
each transmission to be bolted directly to the bellhousing without the use of adapters or
an after market scatter shield, which adds
additional safety and sometimes the only
bellhousing available for an application.
conversion choice you choose depends on what parts you are
starting with and how you set up the clutch linkage.
