cruise control cuts out on downshift

The OEM cruise control in my TJ works great, until there is a hill and the transmission wants to downshift to keep the speed up. Anyone have this issue before? Vacuum line issue?

Sorry you have the same issue, but I kind of feel better since you have the AW4 too. I did the AW4 swap and I wasn't sure, but that could have been when the issue first started (it's been awhile).

Do you think its because the TJ's computer doesn't know how to handle the AW4's shifting? I wonder what the results would be with a TJ's computer that was originally an auto or an XJ's computer that originally had the AW4. Not sure I'd just randomly try this on my TJ my I wonder.
