Hi there,
I know I'm boring you with my stupid oil pump questions, but here's a very simple one:

Does the oil pump of a 1983 TH700 R4 Trans have a gasket between its housing halves? Or do I need to apply any sort of sealant between the housing halves? Or is it a metal-to-metal fit?

The reason I ask this is because in one exploded view I found there isn't a gasket and another view shows a sort of ring, which might be a gasket (I know there's a gasket between the oil pump and the trans shell and a sealing ring, too). And one trans I have has one and the other doesn't - they both don't work
So? What do I do? How do you guys fit your oil pumps?

Thanks a lot and I hope someday I can help others out with trnas-problems, but first I have to solve my own...
