I love my Sport Trac. I actually wish to keep it for many more years. It has worked great for everything I need it to do. I flip cars as a side business. I try to buy only running cars but make more money buying broken cars. Currently I have the non-running cars towed to my house but would like to start using a tow dolly so i can travel farther away from my house to purchase cars. Currently my Trac runs and shifts perfect. I replaced the engine but do not know about the transmission as I do not know the previous history of the truck. Thoughts on using a tow dolly to bring cars (not trucks) back to my house? I would keep it out of overdrive, I drive the truck easy. BTW my trans fluid is clean, would it be smart to add a trans fluid temp sensor?
