I just had a quote of 1600 to do a stock rebuild. No removal or installation.
Advance told me 1800 and I can't remember but ford I think told me 2300.
If you are going to stay stock then a stock trans is fine. If you are going to tow then some simple cheap mods can be done. If you're going to work hard or play hard you need a trans that can hold up to it. You're not into this truck a whole lot so even if you get the lower end trans from bts or wood you are well below the value of the truck still.
