I am in the process of putting my 01 trans. back together, and I have the large pump seals that go around the outside edge of the pump, but I forgot to get new o-rings for where the pump slides onto the input shaft. Looks like there are 2 o-rings. With this new of a trans., would I need to bother replacing these, or can I get away with leaving them alone? I really don't care either way, and would rather replace a $2 o-ring, than have it cause the trans. to puke later on, but hey, a $1 saved right now is better than nothing, if I can help it.
These are highly engineered precision vehicles, the first step in diagnosing the problem is to strike the suspected offending part sharply and repeatedly with a blunt object, then re-test.
