4R70W hard rolling downshift
1997 Expy 4.6L 4x4 230k
Ever since I bought the truck. When I have to slow down from 40-60mph and roll through a corner or waiting for someone to make a turn then get back on the gas it downshifts hard into 2and gear. I have completely flushed the trans and replaced the filter. I dont think there are any codes. But have not run a scanner to confirm this. It shifts nicely otherwise. Tows very well (out of OD of course) and doesn't show any other problems. What could cause this? I'm keeping the truck and if its something I can fix myself I will. Thanks for the help!
