The auxiliary cooler is fully plumbed. And the first drive happened tonight! It was a quick 15 minute run around in the cold without doors or windows. Everything seems to working as it ought to. The transmission temp stayed right at about 110°F.
4.88 is barely ok with 35s. 55ish mph was running about 1800rpm. It's hard to believe this was the common recommendation for so many years. Thankfully the new OD off button works! This definitely needs a regear to 5.38 sometime soon.
Overall, it's a very different Jeep with the automatic. It sounds different. It even starts up differently. The urge to shift after 8 years is very strong.
Eaton lockers and 5.89s
Would be 3000 @ 75.
