I thought the first generation liberty had drain plugs.
Its a 2009. I don't think it has a 42LE, its probably got a NAG-1. Which should last forever behind a v6 since its built to handle the 392.
It's a Liberty it has the 4 speed AT.
Thanks. Had a brain fade there. And I mean to say 42RE, not 42LE, so it was kinda a double fade.
The 42RE is probably the worst-reputation automatic they were still using in 2009, but its not going to be a trouble pit if cared for. The 4xxE series, whether transverse, longitudinal, or rear drive, all have a reputation for being "dusty" (shed a lot of fine clutch material as they wear, especially during the first 50k miles), so filter changes are more important on them than other Chrysler transmissions.
As far as "sealed" transmissions... there's really no such thing. For decades, the standard procedure on *most* automagics has been to crack the pan to drain the fluid. I hate it, so I generally put a drain plug in the pan once the warranty is up. You still have to pop the pan off to change the filter, but at least you don't have to take an ATF shower if there's a drain plug. And I really miss the good old pre-lockup torque converters that have *their* own drain plug. On my '66 and '69, you can drain every last ounce of ATF except that which is in the cooler and cooler lines. Open access plate, rotate crankshaft until the convertor drain plug comes into view, open plug- voila. It also helps reduce the volume of the shower you get from cracking the pan if you drain the convertor first....
