1966 Sunbeam Tiger Transmission
This page is some information on the transmission. The stock
Tiger transmission is still in the car. It is the close ratio
Toploader. A replacement transmission was built up at
David
Kee Toploaders. The make almost every part BRAND NEW.
You can also get the cases in Aluminum! Some configurations
can also have available aluminum tail housing. For the Tiger,
it was unavailable. The selected gear box is an aluminum
case with iron tail housing. Gear ratios were also slightly
modified.

Stock Close Ratio in the Tiger
2.32          1.69          1.29          1.0

Stock Wide Ratio in the Tiger
2.78          1.93          1.36          1.0

Tony the Tigers Ratios
2.44          1.69          1.29          1.0

Nothing like a close ratio gear box, but I'll take a bit
lower first. Note that the Tire and Gear combination
are a
3.54:1 and 205-50-15 Tire. Use the Gear
Calculator for more info. Diff is a Dana TrueTrac,
which is a Torsen diff with no clutches and smooth
transitions. Should make for excellent track work too.

A quick note that David Kee was extremely helpful and
knowledgeable about the Tiger and related
components. A Solid recommendation from me.

To the right are the TrueTrac, diagphragm clutch
cover, dual friction disk, and of couse a David Kee
Toploader. The kit that comes with the Tilton release
bearing is also shown.

  • 61-604 - Adjustable Bearing Wide Flat Face (61-601 is the base size for smaller clutches)
  • 61-618 - Release Bearing Retainer (Ford Toploader)

The instructions are very clear and you need to make sure the unit is properly adjusted. CLICK HERE FOR INSTRUCTIONS

M
ake sure the unit is properly adjusted and use a pedal stop to ensure the release bearing is not over stroked into the clutch
and a likely self destruct of the pressure plate
or the bearing will pop out of the bore if really badly set up. FOLLOW THE
DIRECTIONS!


I have 2 types of McLeod Pressure plates for the Ford. One is the old 3 finger style, and the other is the diaphragm style. I have
run the diaphragm style for a few years in "The Ripper" and have had excellent life and no issues. I may continue to use that
style over the 3 finger unit. Part number that I have from McLeod is 360048 for the Diaphragm style cover. Make sure if your
using a diaphragm style that is fits your flywheel. I recall the later 5.0L diaphragm may have a different
bolt pattern and metric
bolts on the flywheel
