subieL2010 Posted June 18, 2023 Share Posted June 18, 2023 Hey all I'm brand new to the site so I'm sorry if I post anything wrong! I have a 2010 legacy 2.5I, roughly 175,000 miles, CVT transmission(I believe its the base model but possibly the premium) I replaced the transmission valve body because I was getting the P0700 and P2762 codes along with the C0045 and C0057. After replacing the valve body I filled the cvt fluid with the car off, turned it on and idled in each gear for about 30 seconds then shifted to park and refilled the transmission fluid the rest of the way. (12 quarts total put in) Now when I go test drive it, I can shift fine and park and reverse work but when I shift into drive the car only goes backwards? Is a relearn needed to fix this or did I potentially mess up the repair? All parts and fluid was ordered from subaru at my local dealer. Link to comment Share on other sites More sharing options...
silverton Posted June 19, 2023 Share Posted June 19, 2023 CVT fill procedure is not like an AT but maybe it's close? You do need to perform the relearn procedure Link to comment Share on other sites More sharing options...
m sprank Posted June 19, 2023 Share Posted June 19, 2023 Proper replacement and re-fill procedure was not followed. Maybe a relearn fixes it, maybe damage was done. I would normally recommend a re-learn after a proper VB replacement. Link to comment Share on other sites More sharing options...
subieL2010 Posted June 20, 2023 Author Share Posted June 20, 2023 (edited) I did do the replacement improperly, there's a little moveable cylinder with a notch in one end that's supposed to hook onto another piece from the transmission that was missed when installing the new valve body. On the relearn procedure, is it a CVT or TCM relearn? Im curious if I can learn to do it myself or if it's better to take it in. Edited June 20, 2023 by subieL2010 Wanted to add question about the relearn procedure Link to comment Share on other sites More sharing options...
