just enough to take the weight of the trans-
mission off of the crossmmember.
6. Turn the crossmember sideways and
remove it.
7. Place a jacksiand close to the transmis
sion tailshaft. Lower the jack until the trans
mission rests on the stand. Remove the jack
and the wood block.
8. Place a drain pan under the transmis
sion pan. If the pan has a drain plug, remove
it and allow the fluid to drain.
9. If the pan does not have a drain plug,
remove the pan bolts from one side of the
pan and loosen the rest of the bolts. This will
allow the pan to partially drain. Remove the
remaining pan bolts and carefully lower the
pan away from the transmission.
NOTE: If the transmission fluid is dark or
has a burnt smell, transmission damage is
indicated. Have the transmission checked
professionally.
CAUTION: If the pan sticks, carefully tap
sideways on the pan with a rubber mallet
or a plastic hammer to break the pan loose.
DO NOT dent the pan. Avoid prying the
pan off with a screwdriver—this can bend
the pan or crack the transmission case.
10. Empty the pan, remove the gasket
material, and clean the pan with solvent (car
buretor cleaner works well).
11. Remove any gasket material which may
remain on the transmission case.
12. Remove the transmission filter from the
valve body. The filter may have either a fi
brous or screen filtering element and is re
tained by one or two fasteners.
13. Install a new filter using a new gasket
or O-ring (TH400's).
NOTE: // the transmission uses a filter
having a futty exposed screen, it may be
cleaned and re-used.
14. Install the pan using a new gasket.
Tighten the bolts to 12-14 ft. Ibs. in a criss
cross pattern. Recheck the bolt torque after
all of die bolts have been tightened once.
15. Add either Dexron or Dexron II trans
mission Suid through the filler tube. See the
Capacities Chart to determine the proper
amount of fluid to be added.
CAUTION: DO NOT OVERFILL the
transmission; foaming of the fluid and sub-
sequent transmission damage due to slip-
page will result.
16. With the gearshift lever in PARK, start
the engine and let it idle. Do not race the
engine.
17. Move the gearshift lever through each
CLUTCH AND TRANSMISSION
position, holding the brakes. Return the le-
ver to PARK, and check the fluid level with
the engine idling. The level should be be-
tween the two dimples on the dipstick, about
% in. below the ADD mark. Add fluid, if
necessary.
18. Check the fluid level after the vehicle
has been driven enough to thoroughly warm
up the transmission. Details are given under
Fluid Level Checks earlier in Chapter 1. If
the transmission is overfilled, the excess must
be drained off. Use a suction pump, if nec-
essary.
SHIFT LINKAGE ADJUSTMENT

All Powerglides are adjusted in the same
manner, although the shift pattern was
changed in 1965 from the staggered pattern
of 1963-64 to a straight pattern.
1. Disconnect the control rod from the shift
lever.
2. Position both the shift lever and the
control rod bell crank in Park, then loosen
the clevis locknut and rotate the rod until it
freely enters the shift lever.
3. Secure the rod to the shift lever and lock
the clevis nut.

stall the retainer clip.
