Transmission Needs to be Rebuilt - Any goodies I should get?
I've got a 1995 E-350 7.3L, with what is most likely the original transmission. After having some issues with gears slipping, shifting incorrectly, and the overdrive OFF light blinking, my mechanic diagnosed it as a bad converter. Due to its age, they can't find any in stock around the country, so I'm just going to bite the bullet and get it rebuilt.
Are there any particular upgrades I should get? Bigger transmission fluid pan? Cooler? In-dash temperature gauge? 4x4??
