How many miles are on it and has the ATF ever been 'flushed?' You 'changed' the ATF which replaced about 6 qts, but it holds about 16 qts and you left 10 old qts in the torque converter. The only way to completely get all the old ATF out is with a 'flush' and it takes a special flushing machine to do it. If the valve body gets dirty it can cause shifting problems so when you get it flushed have it cleaned.

Replacing the speed sensor was a good call and I think the speedo works off that sensor to.
