B&M 30228 TRANSPAK - Manual (Page 2)

DISSASSEMBLY
STEP 1. Some Turbo 350 transmissions do not have
drain plugs. You may want to install a B&M Pan Drain
Plug Kit #80250 at this time. Drain the oil by removing
the back oil pan bolts and work towards the front slowly.
(Note: Some vehicles will require removal of the
crossmember to remove the pan. Make sure you support
the back of the transmission so you don't damage the
distributor.) Do not remove the front two pan bolts yet. If
the pan sticks to the gasket, insert a screwdriver be-
tween the pan and case and pry the pan down slightly to
break it loose. Now remove the two front bolts slowly.
This will lower the pan to allow the rest of the fluid to drain.
Lower the pan and set it aside. Put the pan bolts in your
tray.
STEP 2. Use a screwdriver to remove two screws and
remove the oil filter and filter gasket. Put them in the oil
pan. (See Fig. 1)
STEP 3. Observe the location of the following: (See Fig.
1) Manual linkage, detent spring and roller, s-link or
offset link, detent control valve link and lever, and support
plate.

STEP 4. Remove pivot clip holding detent control valve
lever in place. (See Fig. 2) Remove the lever also and set
them in the tray. Remove 18 valve body attaching bolts.
(See Fig. 3) Leave the drain pan positioned as there is still
oil between the valve body and separator plate. Remove
the valve body by pulling straight down and disengageing
the manual valve and link from the manual lever. (Do not
let the manual valve fall out of the valve body.) Put the valve
body in the oil pan.
STEP 5. Remove support plate bolts and support plate.
(See Fig. 1) Remove separator plate, gaskets and four
plastic check balls. Leave the drain pan positioned as
there is still oil between the separator plate and the case.
The check balls are between the plate and the case. If the
front servo assembly falls out, install it back in position
with grease to retain it. Order of assembly is: Spring,
spring seat, pin, washer and piston. (See Fig. 7A)
STEP 6. Valve Body: Place the valve body on the bench
with the channel side up. (See Fig. 4) Note the roll pin
locations. Remove the roll pin holding the 2-3 shift control
valve sleeve in place. (To remove the roll pin, push on the
end of the sleeve until you notice the pin move slightly.
Turn the valve body over and let the pin drop out of the
