Did you pull the motor and transaxle in one unit or are you leaving the transaxle in the car?

If you pulled both engine and tranny the tranny should come off the motor with the torque convertor attached to the flex plate. The torque convertor should slide out of the transmission. You may then be able to access the torque convertor bolts.

Pulling only the engine will be difficult since there may not be enough room between the engine and subframe to separate the two.
