1997 Ford F150 V8 Four Wheel Drive Automatic 248000 miles

Hi, my problem is with the 4R70W trans. This trans was having a problem with the last shift as you accelerate it would shift thru the gears ok then at the last shift it would rev like it was in neutral and go into the last shift hard. The trans was rebuilt by a quality shop and was ok for about 20,000 miles started having the same issue. This time if you toggle the o/d switch on the shifter the trans will downshift ok but when o/d is put back on the engine will for a few seconds then will shift hard into o/d. This happens every time at about 40-45 mph. The man at the trans shop is stumped. Help please!

Do you
have the same problem?

Ask if he put in a new solenoid pack and valves as it sounds like a bad shift solenoid or torque converter lockup solenoid. I hope this was helpful
