TFI Swap 87-93 Mustang

We had a twitter follower ask about how to check the TFI.  Being that we are having a problem with the one on the 1987, we have filmed a swap video here.  This swap takes a special tool that can be purchased here:

Lisle Ford Ignition Module Wrench – LIS64650

Here is a link to purchase the TFI module:

BWD Ignition Control Module – CBE32Z

5R55S Transmission

The 5R55S transmission is similar to its predecessors, the C3 and the A4LD.  It is a light to medium duty, rear wheel drive transmission that uses a Simpson planetary gear system to transfer power to the wheels.  The 5R55S was Ford Motor Company’s first 5 speed automatic transmission and it utilizes a series of complex computer controls.  The Powertrain Control Module (PCM) uses information from these sensors to adjust shift points, control shift firmness and torque lockup. The 5R55S transmission was used in 2005-2010 Mustangs.

Gear ratios:

1st: 3.22:1

2nd: 2.29:1

3rd: 1.55:1

4th: 1.00:1

5th: .71:1

A4LD Transmission

The A4LD transmission was a variant of the C3.  It used a Simpson planetary gearset and was a rear-wheel drive transmission that used a hydraulic valve body.  The primary variance from the C3 transmission, was the addition of a 4th (overdrive) gear.  It had a torque converter lockup clutch that was controlled by the Powertrain Control Module (PCM).  The A4LD transmission was installed in 4 cylinder mustangs built from 1987-1993.

Gear Ratios:

1st: 2.47:1

2nd: 1.47:1

3rd: 1.00:1

4th: .75:1

4R70W Transmission

The 4R70W transmission was based on the AODE and also employed a Ravigneaux planetary gear system.  It was initially designed for the heavier Lincoln cars, and therefore had more aggressive gear ratios and more durable parts.  There are two versions of the 4R70W; the first was in the 1996-1998 Mustangs and the second in the 1999-2004s.  The two transmissions differed in that Ford Motor Company replaced the intermediate one-way clutch with a mechanical diode.  The 4R70W is a very tough transmission and can be built to handle high-torque engines.

The 4R70W was revised again in 2003 and given the designation 4R75W.  The 4R75W transmission is virtually the same as the 4R70W, but it has extra sensors to read torque converter slippage and a stronger ring gear

Gear ratios:

1st: 2.48:1

2nd: 1.63:1

3rd: 1.00:1

4th: .78:1

AODE Transmission

In 1992, Ford Motor Company improved on the AOD transmission.  Improvements came in the form of electronic solenoids for controlling shift points, as opposed to a hydraulic system.  The AODE does not use a throttle valve cable for its kickdown, instead relying on the Powertrain Control Module (PCM) to shift.  The AODE was only used in the Mustang for 2 years, 1994 and 1995.

Gear Ratios:

1st: 2.40:1

2nd: 1.47:1

3rd: 1.00:1

4th: .67:1

AOD Transmission

The original concept for the AOD was called the XT-LOD (Extension-Lockup Overdrive).  Work on the project began in 1962 and was an attempt to design a 4-speed transmission based on the Ravigneaux planetary gearset.  Ford Motor Company worked on the project for four years, then abandoned the project.  Ford picked up the project again in 1974 and renamed it the FIOD (Ford Integrated Overdrive).  It would take five years of research and development before Ford Motor Company would put the first one in a Vehicle.  In 1979, Ford changed the name of the transmission to AOD (Automatic Overdrive) and began installing them in vehicles.  The AOD was installed in Mustangs from 1982 to 1993.  Using a hydraulically controlled valve body, the AOD was fuel efficient and sturdy.  A throttle valve cable takes the place of any kickdown rods or vacuum modulators.  Generally regarded as a weak transmission, the AOD is generally replaced with a C4 by serious hot-rodders and racers.

Gear ratios:

1st: 2.40:1

2nd: 1.47:1

3rd: 1.00:1

4th: .67:1

FMX Transmission

The Ford FMX transmission was based on two earlier transmissions; the FX Cruise-o-matic and the MX Cruise-o-matic.  The FMX transmission was basically the result of Ford Motor Company fitting the heavy duty FX internals into the MX transmission body.  It was a hydraulically controlled rear wheel drive transmission with an iron case, aluminum bellhousing and an aluminum tailhousing.  It uses the Ravigneaux style planetary gearset.   The oil pan is mostly rectangular and has 14 bolts.  It uses a vacuum modulator and a kickdown rod.  The FMX was used in the Mustang from 1969 to 1973 and was generally found behind the 351 Windsor and the 351 Cleveland.

gear ratios:

1st: 2.40:1

2nd: 1.47:1

3rd: 1.0:1

June 30 Hooters Westside Car Show

Hooters puts on fairly good car shows.  In Albuquerque, we have 2 and they each do their own.  Here are the Mustangs at the June 30th show on the westside.  This is the first car show that I shot using a DSLR camera instead of my cell phone.  I don’t have much experience with a DSLR camera, so the pictures aren’t perfect.  Let me know what you think.
