hey i was wondering what the tranny line size would be for my car. its an 85 fifth ave with the 318 and 904 auto. i broke a line replacing my radiator the other day due to rust and was just wondering what size line it is. the rubber hose i have doesnt seem to be working so well and makes it shift like ****.

 

I believe it is either 1/4" or 5/16". I'm not positive though.
