ive got a legacy b4 with a triptronic box when i got it it was taking ages to pull away when i put it in drive other then that it was cool. so i got a new used box and now it pulls away fine but jumps into 3rd gear as soon as i pull away, i then took it to diagnostic centre whitch told me it was code 75 line pressure duty solenoid circiut, so i then dropped the sump and changed the solenoids in the sump all 9 of them, but no change it still jumps into 3rd.any idea whats happening
