2001 Hyundai Santa Fe loses power after downshifting to 3rd

i have the same problem as John M., Brighton, IL, US (The car will down shift out of 4th to 3 rd gear and will lose power it will not shift back up and will not go into 1 st gear till it is shut off for awhile )

This is just a guess but I know from experience that solenoids can fail when they’re hot. You could have a shift solenoid on its way out.
