I'm confused about how the AT cooler lines are run. I have two hard lines coming from the AT that terminate at the lower pass side of engine Then (I think) one of them goes into the pass side of the main rad lower tank and comes out on the driver's side then connects to a hard line that goes through the front rad support and then into the AT Rad. The return line goes from the AT cooler to the hard line passing through the rad support and then to the hard line on the pass side of the engine.

Any help appreciated. Esp. a schematic!

What are you confused about?
That sounds right.
The direction of flow.
Which line from the tranny goes into the bottom tank and does this line go into the upper or lower of the AT rad?

That's an excellent question. The FSM does not specify input or output for cooler lines. However, I would guess that the AT temp sensor is on the output of the transmission.
