Introduction
You've seen them in mail order catalogs and on your preffered
online speed parts website, quality tested automatic transmissions
from larger
remanufacturers like TCI or B&M. For years you may have
considered options like a "new" remanufactured Ford
automatic transmission but for whatever reason, you ended
up hunting down a local rebuilder to rework a core you already
had on hand. A decision you rationalized as one based on finances
and enviromental consciousness (aka recycling). Perhaps you
have had some success in the past going this route, but when
you move from place to place, finding and keeping a trusted
performance transmission shop isn't easy. For those of you
who have faced or will soon be facing this common "rebuild
it-or-buy it" decision with regard to any Ford automatic
transmission, this article highlights FordMuscle's experience
in choosing, installing, and road-testing a complete C6 transmission
package from TCI. The TCI set-up was ordered to replace the
problematic C6 in Project
Torino, our fairly modified 460 powered street machine.

This is the entire package we ordered
from TCI. You can see here that installing a new transmission
usually requires more than just a torque converter. |

Think "Package"
It's easy to get tunnel vision when you need a need a new
transmission. Unless you have a clear plan from the get-go
and can assemble your own kit with all you'll need from various
manufacturers, searching for a local rebuilder to overhaul
just the transmission alone can be a mistake. Other than a
converter, TCI has recognized that an enthusiast's need for
a performance transmission also means they'll be needing a
host of matched support parts that make for a successful and
quick home install. (i.e., cooler, dipstick, fluid, and shifter).
Not to mention, most enthusiasts can benefit from the professional
guidance in part selection that only comes from a company
who's products are destined for project cars similar to yours.
With that said, TCI concentrates more on offering their customers
a complete package rather than just a rebuilt transmission.
At first it may seem unusual to think
of a transmission as a package rather than just a combo (transmission
and converter). However, the package concept is what comes
through when reviewing the TCI website, their product catalog,
or when speaking to their technical staff. By logically categorizing
their performance hierarchy of transmissions and torque converters,
it's easy for an enthusiast to get a good sense of what transmission
and converter is right for them prior to engaging with a tech
representative to discuss vehicle combo and your personal
performance expectations.
The sensibility of it all is most evident
with TCI's Sizzler®, StreetFighter®, and the Super
StreetFighter® line of performance street transmissions.
This categorization and naming applies to their entire line
of popular domestic automatic transmissions and is the origin
of any TCI performance transmission package. We've condensed
the Ford line here. Note that the highlighted "StreetFighter®"
Big Block C6 is what we finally chose for Project Torino.

The same logic that is applied to TCI
transmissions is also applied to their line of off-the-shelf
converters. You
can see TCI's full line of converters at www.tciauto.com.
For our application, both FordMuscle and TCI agreed that the
11" Breakaway (PN 441000) for the Ford C6 with 1.375"
crank pilot was right for our street-minded application. In
fact, the advertised 2400-2600RPM flash stall was a perfect
match with the recommendation provided by Comp Cams for the
Xtreme Energy XE274H cam we chose for the Torino's 460 a few
years back.
