The NAG1 is/was a fine Transmission, all the major bugs were figured out while it was a W5A580 under Mercedes before being built stateside as the NAG.In my mind, I keep thinking the US side of FCA does not exactly have a good reputation for automatic transmissions. I miss driving manual in addition to that.
The NSG370 manual from Mercedes is more notoriously buggy / problematic.
So I would disagree with your assessment, and I speak as an owner of all 4 variants (old 2nd Gen NSG in 2008 JK / new NSG in 2015 JK and W5A580 in 2012 JKUR / NAG1 in 2015 JKU).
I like both manual & auto JKs, but these new transmissions should improve on the shortcomings of both prior offerings in the Wrangler.
That being said, I’d still prefer a ZF sourced 8HP75 over a US sourced 850RE, but that’s due to torque handling, and the hope for the better alternate ratios/spread.
