I have a 2002 F-250 Lariat Crew Cab SB 4 by 4 7.3L Turbocharged Diesel V8 OHV 16V. It has a 4 speed automatic transmission. I hate to sell it because I have so much invested in it but I have been wanting a Manual. I was just curious to know if there is any way to have the transmission changed from a 4 speed auto. to a manual? If so how much would it cost to have this done? Thanks
