i have the same downshifting /noise problem on my car…
The same problem as what? As who? We don’t know what you’re referencing so help is unlikely.
the transmission issue…not down shifting easily…maybe a TCM issue?
Okay, that’s better. As you noted, you’re not alone. The problem could be as simple as low transmission fluid. Assuming you’ve eliminated that yes, it could be a faulty TCM. Or a bad speed sensor. Sorry but I’m not a mechanic and I can’t tell you what’s actually wrong.
