I just bought a 95 f-250 with 260,000 miles on it. The tranny is a factory replacement. Im not sure when it was replaced. The truck drove fine for the few days that I have had it, but last night it started to act up. It wont shift out of first gear. All the way up to 3000-3200 rpm's and it stays in 1st. If i let off the throttle and get back on it it then shifts but kind of hard. The tranny fluid has a kind of burnt smell to it. Also it has a Banks Transcommand. I unpluged the transcommand and test drove it and nothing changed. I really need some advice b/c im 17 and just got the truck and havent even paid it off yet. Thanks in advance.
