just sounds like when you had the T case fluid changed, they over filled it.

they prolly used a pump and were able to get alot of fluid in there, and/or a stupid tech working on it and just simply over filled it.

maybe i am wrong, but the tranny temp sensor does nothign for the T case. its only for the tranny.

you let it drain, so you should be good to go now
