<< It was cheaper to buy a good used tranny and have them install it
in most cases.>>

I am really sorry for cutting in on this conversation.

For some reason the last thought in this message doesn't work.

"Good" & "Used" just doesn't fit together.

I believe that as long as you were going to the trouble of having the seal done, why not have the whole transmission gone through and be assured that the trans woe's would be a thing of the past.

This is how I would think that the job should be done.
