2006 Matrix shifting issue Sign In

I have a 2006 Toyota Matrix 135k miles, a few weeks ago coming home from work, i was going approx 55mph and it dropped out of high gear down into 2nd gear, tach went up to 4000rpm, so i babied the car home about 3 miles in second gear, next morning i go to work was ok, coming home it acted up the same as before, babied it home, next day i dropped the trans pan cleaned it up, installed new filter and pan gasket, and filled with castrol trans oil, was ok for 3 days and did the same thing, i scanned it twice with my Actron scanner, no error codes. i even tried the lucas additive did not change anything, i have it to a point now i can almost predict when its going to drop out of drive, if car sets overnight, i can go about 7 to 10 miles and it will act up, if i come to a stop, car will shift normally from 1st to second and stay in second gear, i called a trans shop and he was saying it sounds internally problems, my other good friend has a buddy in the trans business says it sounds elec, like a speed sensor, can it be a speed sensor if i never get a check engine light or why it does not show on the scanner,

Hello,
Kinda sounds internal, but here's what you can do. When the car starts to act up, have the scanner on it, you have to see if 3rd gear is being commanded or not, this should show in the live data part of the scanner, if 3rd is being commanded, it's internal, if it's not being commanded then i would start looking at sensors.
