Approaching 100k miles on mine, no problems to speak of. I'm going to look into the re-flash though. I just don't like that wierd way this tranny shifts, cutting power back until the gearchange is completed. It's just too long and drawn out. If the flash helps quicken and maybe even firm the gearshifts, I'm all for it.
I've been meaning to do it for months now, but I'm going to call my Ford dealer and find out more about it.
If my tranny does eventually fail, no big deal...I'll just toss in a low-mileage used one from the salvage yard and keep on motorin'. I've priced them already, and I can buy one with 30k miles for ~$750. I can do the install myself, so it's not a big deal really.
I can't see spending thousands upon thousands of dollars to have one rebuilt, when there's perfectly good used ones to be had for a fraction of that cost, and most come with a decent warranty, with longer warranties available for purchase if desired. I've met some of the monkeys that work in tranny shops, and to be perfectly honest, I wouldn't have them wash my socks, say nothing of having them tear into my transmission. At the dealership, we've had more trouble with rebuilt engines and transmissions than just getting "virgin" low-mile used parts that have never been molested. Rebuilt parts to me just means one more element of human error that wasn't there to begin with. Most the time I'm right too, as the majority of the failures with the rebuilt parts can be pinned down to something that was improperly assembled, or not thouroughly inspected.
Just a few random thoughts is all.
