Hi Jim

In my case its downshifting okay but the problem is with upshifting
from 2 to 3. If I press on gas pedal a bit harder (than what I usually
do) the shifting has no problem. What I will do is to have these
responses printed and take them to my mechanic. I like to get this
things sorted. The car is otherwise fine.

By the way, what motor you are talking about? Is it related to the
engine or the transmission? (Sorry, I have no idea about auto
engines).
