On my '97 ZJ 4.0 stock auto trans the trans pan is looking like it's gonna rust thru any minute.
Where can I get a decent priced replacement for that?
Vehicle is in New Jersey garaged for when i go there for work

 

There are plenty of trans shops around here for me to ask about stuff like that. Most of the shops will probably have cores laying around to sell you a pan. Might even hit up a salvage yard, they probably wont sell you one unless its a junk core though. other than that there are a few options on the internet for stock or upgraded, or hit up the dealer.
