2–4. REMOVING MOUNTING BOLTS
• Support the transmission securely on a jack, hoist, or other removal support
equipment.
• Remove all bolts and supports that attach the transmission to the vehicle.
• Remove the 10 or 12 bolts that attach the transmission to the engine or
adapter.
2–5. REMOVING TRANSMISSION
• Move the transmission rearward until it is clear of the engine. Use
care to prevent the torque converter from separating from the
transmission. Keep the transmission level or the rear slightly low to
prevent the torque converter from slipping forward. Remove the
adapter ring (if used).
• Attach a retaining strap (Figure 2–2) across the converter drive cover and
transmission housing at the earliest opportunity.
2–6. REPAIR INSTRUCTIONS
• Refer to the applicable Allison Transmission Service Manual to repair the
transmission. Refer to Paragraph 7–2.
NOTE: When an adapter is used to adapt the transmission to a larger
engine flywheel housing (Figure 2–1), remove only the transmission-
to-adapter bolts.
CAUTION: Do not pull the transmission away from the torque
converter assembly. The torque converter drive cover must be entirely
free of any restraint by the flexplate drive or crankshaft pilot when the
transmission separates from the engine.
