My 2018 Ram Promaster City Van (2.4L 9 speed auto) only has 20k miles and has never been near water or off road. However I did do some aftermarket electrical work. I was out of town last month and when I cam back it would not start. When I opened the hood the battery had blown up and damaged some electrical and plastic lines. I took it to the dealership and they wont cover it as it's my fault. Is it possible for battery acid to cause water to get into the transmission? If I've not driven the van since the event, any chance I can fix this without a transmission replacement? See this image:

Not quite sure what I was looking at but YOU said "aftermarket" and found battery blown up.

No telling if full power of battery shorted for any reason what damage it would do only 12V is still powerful if a direct short.

Of course it's now all yours not on warranty you just messed up something big time MOPARS (nick name for anything to do with Chrysler Motor vehicles) or anything really isn't going to like that.

IDK how "water" got anywhere unseen in that picture to me even battery acid doesn't eat up plastic but will short on anything metal.

IMO putting on "aftermarket" junk of any kind that doesn't just plug into a power port is about like throwing a hand grenade at the thing with the pin pulled - sorry for your troubles bet you don't do that again,
