I use a 3 to 4 foot long big chain,3/8 or bigger to remove the front pump from the tranny. Remove all the bolts holding the pump into the tranny and use two 3./8 by 2 to 4 inches longs bolts with flat washers holding them into the chain links and screw them into the threaded pump holes on each side at 9:00 and 3:00 clock position and jerk on the chain until the pump slides out
Crude and it works
