I was out at Great Lakes drag way this weekend here in wisconsin running my 06 F250XLT. Saturday was great, ran 14 flat all day in the 1/4 mile. Mods listed in sig. Unfortunately the stock trans and T-case did NOT like 4x4 launches under high boost. On my way home yesterday from the track, it all of a sudden felt like i was stepping on the brakes but i wasn't, and my foot was still on the gas. i heard a *tink* and everything went. No gears, Fluid everywhere, dead on side of the highway. I got it home last night and the trans is shot. What do you think my best plan of attack is? Rebuild this one, or buy a new trans. Has anyone had any luck with Holderdown Performance trans? Stage 2 for $4000, and it holds up to 850 horse? seems almost too good to be true. Im 18 years old and working with a budget. My truck will be sitting until I've got enough to fix it but I guess I'm looking for some input. Thanks!
