Transmission not shifting properly
My car is a 99 mercury cougar an automatic
when i put it in drive and start driving. It
want change from 1st to second gear to like
20 to 22 miles per hour the rpm go up not
realy a whining sound just like you know ok
the shifting is not doing right like hesitating
to change but it changes and changes
smooth. What could this be and how hard to
fix . also fluid is full and clean
