4L60E - 4L80E Trans Brake
Operation
Brake will function in drive
position, not manual low unless you are using a Ross-Lock™ patented hybrid
manual box, and be disarmed in overdrive position. Never stall engine against
converter with the brake applied for more than 3 to 4 seconds. Anything over 3
to 4 seconds will overheat fluid causing damage to transmission and converter
and may also cause a flash oil fire if the front seal fails. When brake is used
you must have proper tire contact with pavement. (dry and clean) Never use brake
unless tires are hot, sticky and in contact with pavement. Failure to do this
can result in failure to internal low roller. Also never use brake as a line
lock for burn out. When applying trans brake place shifter in manual 3rd
drive position, depress button (DO NOT LET GO OF FOOT BRAKE) at the same time
you depress the trans brake button (because line pressure at idle is set for
street driving it will be between 75 and 85 PSI instead of 175 to 200 with
competition transmission) the brake will need a second or 2 to apply for best
results push button , hold foot brake for a 123 count. Then lift foot brake
pedal. Now you are ready.
