4r55e questions
hey,
i ran into a couple of problems with my 96 4.0l. first i replaced the flexplate for the second time this year. both times it sheared in two. im trying figure out the why to this problem, so i dont have to do it again. i noticed some mechanical damage when i pulled the torque converter out. the backside of it and the front of the transmission housing were galled, like they had been rubbing against each other. i also noticed when i removed the flexplate, there is a 1/2 inch or so spacer between it and the crank that was also slightly damaged. im thinking that the TC and spacer damage are an end result of the flexplate and not a cause, since when everything is working normally, the crank, spacer, flexplate and torque converter should all be bolted together in one piece. i dunno. id appreciate any thoughts.

Hello, I being a former dealership trans tech have seen this problem many times. We fixed this by checking the spacer that is inside the flywheel, installing one torque converter nut snug by hand, rotating the converter/flywheel 180 degrees and installing another nut to bring the assembly together straight and true. Then install the other two nuts and tighten them all. We found that by doing this each time that repeat repairs disapeared. you might also check the snout of the converter and see if it is galled up that will cause binding into the spacer. If the spacer is damaged in any way, replace it. The alignment trouble could cause premature flywheel wear and breakage.
Hope this helps,
Jim
