Weary purchaser - Toyota Yaris Forums

The shifting issue could either be a worn synchro due to improper shifting habits, or it could be it needs RedLine MT-90 put in to improve shift feel, and that might help as well with the synchro. A lot of owners including me switched to RedLine MT-90 to improve cold shift feel and eliminate notchiness-which it did. Do a little research on worn synchro symptoms and see if it matches what you're experiencing. Worn synchros are expensive to replace and not worth digging into, so if you go for it you'd probably just have to live with the issues. I have not experienced this problem with my Yaris, I do however have a Miata that has this issue from first to second-till it warms up, but is a built in glitch with this car and has never gotten worse in 100K miles.

The OP has an automatic transmission. Isn't the MT-90 for manual transmission?

It's not that complicated, the auto in the Yaris will not shift into top gear until it is properly warmed up.
