Installed my Yank today!!!
I have a few questions for you guys with stalls.
After install, is it normal when you pull up to a stop light the RPMS take a couple seconds to go back to normal? It holds at about 1100 rpms, and then finally kicks down..
I know the Break in period is very strick on new stalls, but if I go on the highway, is it fine to kick it up over 3600 rpm? And see how it feels??
Well thanks.

BREAK IN PERIOD…
Yank converters have a special clutch lining material that requires a special break in procedure.
This procedure consists of:
Driving the converter at normal speeds with NO WOT starts or brake stalling the converter for approx, 150 miles.
Stall checking or Brake stalling will severely damage the clutch lining if converter is not broke in properly. This will void any warranty.

Mine idled fine...right at about 850-900 like always. The stall doesnt really feel like it makes a difference on the highway, 1st gear is...

Have fun.

Stalling it up effects the roller clutch and bearings that are new and have to be run in to allow for full contact surface, if this if not done you can pit or over heat the bearings and stator internal parts.
This also will allow for all the trapped air the be purged from the converter
the converter clutch has to be broken in same as your brakes would, as all high spots and compacting of the lining surface must be done to allow full contact area.
This will apply on Yank converters as other brands are built with USED parts and do not need this attention as they have been broken in from the converters previous life.
