[QUOTE="IHPowerstroke7.3, post: 411249, member: 7642"] I would put the new 6 speed up for the challenge against any other light duty truck transmission on the market and I bet it would take the cake. Just like the 6 speeds in the f150 which they are based on they are tough. Ive yet to see a 6 speed in an f150 have a failure other than a fluid leak. Most of the 6r140 problems i have seen have been solenoid/software related, and there is a Bulletin for the issues and solenoids are changed. I have pulled at capacity with my dads 10 f150 a trailer weighing just shy of 10,000 lbs. I pulled the pan for service at 30 000 miles, looked mint. Less clutch material then i expected to see. I have pulled pans on a few 6r140s for service and they are the same, clean. One i did the other day was a 6.2 gasser, 120 000 kms first service, spotless. Truck had a pintle hitch on it and it looks like it gets used often. They did there homework with it. Trying to get the same toughness with different programming may be tough but possible. Hate to say it and don't want to sound like an ass, but customers wanting smooth, gentle shifts in a light duty truck transmission need to give there head a shake. [/QUOTE]
