2. The line goes along the drivers side of the engine beside the oil pan, the check valve screws onto the front of the metal line.
As in as soon as it leaves the radiator?

5. Other than the valve, filter & fluid, that's about it. Mine had a Mopar reusable pan gasket. If that's what yours has, I suggest staying with it, as I had issues with the rubber gasket that came with my filter leaking afterwards. Valve body removal is required to do the Sonnax manual valve, and it's kind of tricky getting the park rod back into place once you've removed it. If you're not 100% comfortable with going into an automatic trans, I'd suggest taking it to somebody who is.
6. The manual valve is in the valve body, and it's the valve that is directly moved by the shift lever.
This confuses me. In one of the pics above, it shows the valve somewhere between the hard line and rubber line near the radiator. Maybe I'm mixing up part names, though. I thought the Sonnex valve was the one in the pics and waht was being referred to as the manual valve.

The overnight fluid leak is more than likely going to be the seal where the manual lever (the lever that attaches to the manual valve) passes through the case.
That's one of the seals that was replaced.

We have a new 4X4 shop in town and I talked to the owner about my issue the other day. He said the same thing. They were chasing a leak all over the place and turned out to be a mud dauber nest in the vent tube. This not out of the realm of possibility for mine but the hesitation upon start up makes me lean toward the valve or another issue.

Thanks, everyone!

The check valve goes in the line leading to the radiator. That means for a 2002 or older TJ, the check valve goes into the line that connects to the driver's side of the radiator. For a 2003 or newer TJ, the check valve would go into the line that connects to the passenger-side of the radiator.

When you have a choice, buy American.
