The Turbo Action CHEETAH Pro Series Brake gives you the same clean and positive shifts that
you have come to expect from a CHEETAH Valve Body. In addition, you now have a Tranz Brake
which will allow you to compete easily with or without a delay box. Special features include: Roller
clutch protection due to a timed delay on the rear band release; Tranz Brake works in first gear only;
no extra horsepower loss due to high line pressures; exclusive “Power Lock” brake system
circuitry; quick release; high reliability; low current draw and easy installation (no internal modifica-
tions required).
Deep Oil Pan Required w/proper pick-up (Must be single hole pick-up).
Options that should be considered:
1. If “727”, suggest 12-15 #17090 springs for front clutch piston.
2. If “727” & “904”, suggest 3.8 Kickdown Lever or a 4.2.
3. If “904”, be sure that “904” transmission core is a 1971 or newer. Part Number
will be 35XXXXX or higher.
The following are the proper settings for your bands and clutches:
Front Band - “727” & “904”: Adjust front band per the following specs - (a) Locate the adjust-
ment on the driver side on the outside of the transmission, just ahead of the linkage. (b) You will
need a 3/4” wrench and an open end 5/16” wrench. Break the locknut loose (3/4” nut). Now
holding the locknut, turn the square lug in the center of the locknut with your 5/16” open end
wrench. Turn wrench clockwise until wrench becomes snug (10 in./lbs.). Make sure the locknut
doesn’t move while tightening the square lug. (c) Now carefully turn 5/16” wrench
counterclockwise 1 1/2 turns. Holding the 5/16” wrench, tighten the 3/4” wrench to 35 ft./lbs.
(Very Tight). DO NOT allow the square lug to move while tightening the 3/4” locknut.
Rear Band “727”: Tighten adjustment lug 10 in./lbs., back off 2 turns and tighten locknut.
Rear Band “904”: Tighten adjustment lug 10 in./lbs., back off 4 turns and tighten locknut.
