TH 700 oil pump gasket?

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 :mad:
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... :confused:

no there is no gasket where you put the pump halves togother. dont put anything there. make sure its clean. o ring goes around the out side. gasket between pump and case.:)

You will also need a band clamp to place around the OD of the pump to locate the two halves properly.

Thanks a lot, that's what I wanted to know :)

I guess that could have been the problem with my pump: It didn't build enough pressure and I kept getting pressure flutter. Probably because the oil went all over the place inside the pump but not enough in the right direction through the right channles :D
Seem to be getting there...
