Thanks everybody I think reading the codes will be my next move

I didn't notice any

last night on the way home from work I tried to narrow it down a little, in 4th it keeps going from 1500 rpm to 3500 back and forth this is at about 40 mph , when it was at the higher rpm I downshifted 3rd and there was no change in rpm . I also tried this at 60 mph low rpm was 2500 and close to 4000 when it kept downshifting. I also downshifted at this speed and there was no change in 3rd at the higher rpm. So for some reason it's going into passing gear or 3rd . I also believe it's a sensor or TCI but finding out which one will be tough. Thanks for all the help you guys

No I'm not sure , I thought that also but this is my first Subaru and problem with a locking torque converter ,what would cause that?

all speeds 4th to 3rd THANKS for replying

I just picked up a nice 98 outback for 500 bucks knowing that it has trans problems. The fluid is clean with no burnt smiles but it keeps downshifting even on the flats. Is it the TCU or ?. No codes are showing
