4R70W Lost 3rd while towing

Coming home from fishing this weekend I was getting ready to climb a hill and dropped the OD out, lo and behold I lost third gear in the transmission. I can drive with OD off and the tranny weill never leave 2nd, with OD on the tranny shifts to third at around 55mph and the tranny slips 100%, I suspect I blew out a shift valve or solenoid, checked fluid level, OK, the tranny has 165K of hard towing, and I jsut installed a NEW engine last month....thoughts on this

Did not blow third, blew the OD Band. All of the crap that comes apart from this really hammers the tranny and block the ports.

Monster box it

I agree - MONSTER BOX

Go to:

Monster box built by Greg Evans who works for Ford building transmissions. You cannot kill it. Great for heavy duty operation.

Good luck.....
