B&M 10225 SHIFT IMPROVER KIT - Manual (Page 6)

STEP 13. Tighten fourteen screws attaching transfer plate
to casting on the bottom of the valve body to 35in. lbs.
Tighten all end plate screws to 35in. lbs. Adjust pressure
regulator spring retainer from side to side until the distance
from the manual valve to the adjusting screw is 1-7/8". Use
the gauge supplied to check this measurement. (See Fig.
12) Tighten three short retaining screws to 35in. lbs. At this
point all screws should be tight.NOTE: Adjustments are the
same for large cage models.
STEP 14. Pressure regulator adjustment: Use the gauge
to adjust the distance from the casting face to the inside
edge of the pressure regulator spring adjusting plate. (See
Fig. 12) Use a 3/16" Allen wrench to adjust the plate to
dimensions shown:
Heavy Duty: 1-1/4"
Dimension “A”
Street/Strip: 1-3/16"
Inspect your oil filter. If it has varnish on it, or the transmission
has more than 20,000 miles, we recommend you replace
your filter. Use B&M Filter #10288.
STEP 15. Guide the valve body up into the transmission.
Insert the park rod into the hole in the rear of the case first
and rotate the drive shaft until the rod engages the pawl.
(See Fig. 13) Align valve body with case and install valve
body against case. (Be careful not to damage neutral safety
switch. A small screwdriver can be used to retract the
switch out of the way during installation.)
STEP 16. Install shift lever over manual lever shaft and
tighten pinch bolt. Install throttle pressure lever over throttle
pressure shaft and tighten pinch bolt securely.
STEP 17. Clean oil pan and install in place with new
gasket supplied with kit. Install pan bolts and tighten to
150-in. lbs. Check your drain plug if you have one and
make sure it is tight!
STEP 18. Check shifter adjustment. Place shifter in park
position. Loosen the pinch bolt on the shifter rod (which is
located on the end of the rod away from transmission) and
let the rod seek its own position. Tighten the pinch bolt and
check the feel of the shifter. The detent position should be
close enoughto the gate stops in neutral and drive so that
the shift selector lever will
not remain out of the detent
position when placed against gate and released.
STEP 19. Throttle pressure adjustment: Make sure
carburetor is off fast idle cam so throttle is in normal idle
position. (Hot idle position) Have someone push the throttle
lever on the transmission all the way forward. Adjust the
throttle pressure rod so there is no backlash between the
operating stud on the carburetor and the back of the slot on
the throttle pressure linkage.
STEP 20. Lower the vehicle but keep the rear wheels off
the ground if possible. Pour four quarts of B&M Trick Shift
or Type “F” fluid into the transmission. Trick Shift is superior
in lubrication, heat capacity and friction material performance.
We recommend Ford fluid over Dexron or Type “A”. Start the
engine and allow it to idle in neutral. Check the fluid level and
fill to the “add” mark. Shift the transmission through all three
gears several times. Check the oil level and make sure it is
at least at the “add” mark.
STEP 21. Drive the vehicle for one or two miles to
thoroughly warm the fluid. Minor adjustments in shift
points can be made at this time. Shortening the rod will
lower shift points, lengthening the rod will raise shift
points. Note: All vehicles must have throttle pressure
linkage regardless of intended use. Running this
transmission without throttle pressure linkage will
damage it. Check fluid level with engine running and
shifter in neutral and make sure the level is between the
“add” and “full” marks. Do not overfill!! This will cause
foaming and overheating.
