What cars will the Tremec TKO fit?

The Tremec that started it all, the 3550, circa ’95. The first transmission that Tremec built was for the Cobra R in 1995. A year later, Tremec would take over production of the Mustang’s transmission line up to the 2010 model year.

Why did Tremec make the 3550?

The reason Tremec made the 3550 was to replace the production use of the then competeing Borg Warner T-5. The T-5's were breaking and Ford was paying to warranty them and have the service techs rebuild them on the bench. That was not very successful.

What is a TKO 600?

Hi Joe,#N#The TKO, TKO-500 & TKO-600 are all TR-3550 's. They all share the same bellhousing for the 302 SROD 4 speed. The Top Loader also has the same bolt pattern but the Top Loader has a shorter input shaft. That's why when you install a TR-3550, TKO, TKO-500 or TKO-600 on a Top Loader bellhousing you always need either a spacer plate or short input shaft. The short input shaft kits I developed in 1994 so it would fit classic cars with a Top Loader. For 1 3/8" input Top Loaders I make a spacer sleeve to fit the big throw out bearing so you can use the stock fork & pressure plate.

When did the TKO 600 come out?

The TKO-600 became available in 2003. The 3 vehicles that had a Tremec 3550 was 1993 Cobra-R, 1994 & 1995 Cobra-R. They were not production cars but assembled for Ford.

That was not very successful. Ford went to Tremec (who had made the Mustangs earlier SROD 4 speed that had an overdrive) to make a more durable 5 speed overdrive tranny. Tremec took an existing tranny they made for the South American light truck market which was the TR-2550.

Does the TR-3550 have bellhousing?

Hi,#N#One last thought. The reason the TR-3550 uses the same bellhousing as the SROD is that the SROD & Top Loader are all the same centerlines between the main & countershaft. In other words the Top Loader, SROD & TR-3550 are all related in design...

Standard height or low profile

TREMEC TKO’s can be installed into 65-66 Mustangs but requires raising the tunnel 1.5″ to make room for the taller main case. If the transmission tunnel is not raised the transmission driveline is greatly effected which will induce a vibration problem on de-acceleration. However, with the optional low profile TKO this issue is resolved and the TKO can fit into many of the vintage cars which came with small tunnels..

Clutches and flywheels

Using the R model bell housing with a clutch cable kit or hydraulics, will require using a diaphragm pressure plate found in late model Mustangs. 302 engines dated 1981 and earlier will need a 157 tooth 28oz imbalance flywheel, as do the 289 and 351 blocks, regardless of year.

Crossmember

Since the TKO transmission mounting point is further back than stock 3-4 speeds, a TKO cross member is needed for vintage cars. The cross member is designed for use with the stock early style rubber transmission mount, so don’t make the mistake and purchase a late model T-5 transmission mount as it will not work.

Shifter

The TKO shifter has two threaded holes to mount almost any kind of shift lever desired. We offer both a stock like appearance shift lever, ball and boot and the Hurst classic style. For those who like the Hurst look of the 60’s, there are several chrome levers to choose from. Hurst also offers five speed pattern shift balls in white and black or T-handles found in vintage cars..

Speedometer

Be sure to save the automatic transmission speedometer cable, as it can be reused. You will, however, need to install a speedometer driven gear, which are available in a variety of tooth counts to match your differential gear and tire combinations.

Neutral safety switch

Automatics have a neutral safety switch, so that the car can only be started in park or neutral. Manual transmissions don’t need the switch, which must be by-passed or the motor will not start. On early Mustangs the four-plug harness sticks out of the firewall above the master cylinder.

Starters

The starters from early 289-302 Fords with automatic transmissions work just fine. The starter from any ’85-’95 Mustang 5.0, auto or manual, will work. When header clearance is an issue, 1992-95 5.0L Mustangs use a high-torque starter which will run about $130.

So to give you the story to date up untill recently my car had a 5.0/AOD combo in it that came out of an 88 mustang that was on the loosing side of a car/truck accident.

Nice install! Got any pix of what the M/C looks like mounted to the firewall and how it attaches to the clutch pedal? Is that part of your install a "bolt-in" or does it require fab work?

I started reading your post and thought... uh oh, will he still get full range of motion with that master cylinder? But you said the cylinder actually bottoms out before your foot hits the firewall/floor. Awesome! Great job!
