97 Linc TC shiftilng

Just started in June my TC down shifts violently when called for in extremely hilly terrain, otherwise shifts very smooth. Only 82M miles could it be trans fluid needs changing? Can you reply via email, can’t alway listen to radio.

When was the last time it was changed? I believe that the 97 called for a fluid change every 30K miles.

Because the tr fluid looks so clean/red and nobody pressed me to change it has never been done, is non changing a known cause for violent downshifting?

Wow, 82 million miles??? Thats great. Just kidding. Non changing is a known cause of transmission failure. I would scan the computer for codes first. That harsh shifting could be a result of an electronic problem. A faulty TPS for example. Dont condemn the transmission just yet. All avenues must be explored.
