Question Transmission

I have a 2001 f250 power stroke with 233000 miles. I have changed the trans fluid at every 50,000 miles. This trans just quit going forward out of the clear blue. When it would go forward it went through the gears perfect, if you put it in park with the engine running after a few minutes it won't move forward but backs up great. Sent it to the shop they said it was the converter. So they changed the converter and pump. Now it is worse it starts off and then after about 2feet it drops out of gear. If you give it WOT it will slip and start moving then it will go through the gears. On the way home it would down shift just going over an overpass on the interstate. Any ideas?

Thanks. Rick

I'm not a tranny guru, but I think the phrase is, "stick a fork in it- it's done."

A BTS or a Ford HD would be good options.

The shop didn't know what they were doing. If it were the converter it wouldn't back up or go forward. Stick a fork in it - it's done. It isn't electrical, it isn't the converter, and it isn't some adjustment. It has had a mechanical failure that will require a rebuild or replacement.

As the other have said "stick a fork in it" my tranny did the same thing, one minute is was fine then the next it would barely move forward but reverse was fine, new tranny had to go in. I'd get my money back on the parts that where already changed because they where not the fit.
