Question about recall

I took our Grand Vitara in for the recall on the throttle cable. After the service the car shifts too early
(@ 4000 RPM)when at full throttle, and it doesn't downshift when it is supposed to either. Could this issue be related to the other issue? Could something have been disrupted with the swa of the cables?

A few months back I took my XL-7 for the recall, and I haven't notice any change before and after. Maybe they did something else to it. Take it back to the dealer so they can fix it right.
