Transmission Disassembly Tips
It is advised to first remove the valve body/conductor
plate assembly from the transmission clearing the Hall
Effect Sensors from the barrel of the case.
Begin by removing (2) # 45 Torx bolts used to attach the
converter housing to the main case as shown in Figure
13. During assembly, these bolts tighten to 14.7 ft. lbs
(20 Nm.)
Next, rotate the transmission on it’s back and remove
(6) # 30 Torx bolts and pan clamp down fixtures
(Mercedes calls these spacers “sprags”) and then
remove the pan (See Figure 14). When re-attaching the
pan, these pan bolts tighten down to 5.9 ft. lbs. (70.74
inch lbs./8 Nm).
With the pan set aside, the filter can be removed with an
upward pull (Figure 15). Using a 7 mm socket (9/32”
works also), unscrew the vehicle harness connector
sleeve’s attaching bolt and pull the sleeve out of the case
(Mercedes calls this sleeve a “Guide Bushing”).
Remove the Valve Body’s (10) # 30 Torx retaining
bolts. 6 across the top and 4 across the bottom (See
Figure 16). When re-attaching these valve body bolts,
tighten down to 5.9 ft. lbs. (70.74 inch lbs./8 Nm).
After the valve body attaching bolts have been
removed, the valve body may be lifted up off the case
and disassembly of the transmission can begin. To
continue with transmission disassembly turn to page
27. For valve body information, continue to page 14.
