when bolting a tranny to a motor...

pour about a quart in the converter....

once the motor and trans are mated , you can move the converter from underneath to line up the flexplate with the converter bolt holes...

dont put any trans fluid in the trans until it is in the car unless you want it all over your driveway..

one more thing...

one bolt on flexplate and converter is offset.....before you bolt the flex plate onto the engine..lay the flexplate on the converter and get all 4 bolt holes lined up....then paint a mark on the flexplate and converter so you can just line those up ...otherwise it could take you several trys to get all 4 bolt holes to line up on the flexplate and converter

and do not tight up any converter bolts until you have them all started...just screw them in so they dont hit the back of the engine while turning it to get to the other bolts
