7.3 diesel auto tranny, obvious leakage on the right side exhaust, 2 piece tranny dipstick tube is flopping around,is there just an o ring on the joint? overdrive light flashes as well. also oil leaking out of starter and flywheel cover. cant tell if engine oil or atf, the obvious leak has coated the rear end of truck with atf its red there, my guess so far is dipstick tube for the atf. Any ideas?
