hey all
I have a 97 f150 4.2L w/4R70W tranny - i have been getting a horrible grinding noise while in drive/reverse - only on acceleration - it's been driving me crazy trying to locate it
i went under and rapped the shields and cats and checked everything
replaced L motor mount cause it was shot - replaced all u-joints and greased the slip yoke
today i yanked the tranny out - thinking the flex plate was going - nope
that wasn't it - entirely
the problem seemed to be - the flexplate - was rubbing on the separator plate which i didn't think the 4.2L is suppose to have --- the back side of the flexplate was scuffed up and the sep plate also had bright shiny spots on it
also the starter drive gear was kinda chewed up at the very front like that was the only thing making contact with the flywheel
ok
So my question is can I leave off that separator plate - or does it do something more than cause problems
thanks

Success !!! I left the sep plate off - the truck runs great and the starter is making better contact with the flex plate ring
while i was under there i also changed the 3 u joints and lubed the lubeable front end parts that had zerks
have a great day
