Had the engine out to do a few jobs, on refitting it I cannot close the gap between the engine bell housing and the autobox. Is there a trick to this or just keep trying.

Thanks

Does this help at all? - http://www.symatix.co.uk/300zx/EngineRemoval/EngineRemoval.htm

try turning the flywheel to help locate the boss on the front of the torque converter.

if you have help: have someone turn the crank-pulley while you "wiggle" the box into place.

 

 

if you are alone: use 2 long bolts on the left and right side of the bellhousing (where the small bushings are that need to fall into place with the bellhousing)

Tighten both bolts (not too tight) and rotate the crank-pulley, tighten bolts, rotate pulley and keep repeating this until the box slides into place.

 

PS: for both methods it's important the box is level with the engine.
