2000 4R70W intermittent no Drive(3rd) on upshift.
I finally found the problem, Thanks I-M Tech you were very close to being right on the money. http://www.ford-trucks.com/forums/78...-3rd-fine.html
When I went to buy the 2-3 Accumulator Piston the parts guy at the transmission shop suggested I also buy the 2-3 spring as well as he said they find the 2-3 spring broken often.
Well imagine my surprise, I found the spring for the 2-3 Accumulator Piston broken into three pieces.
The transmission shifts perfect now.
