My 2000 Honda Odyssey was slamming into 2nd till it started slipping. I put in a used solenoid. . . . But it still slips in 2nd and another symptom is tcs light comes on after 5 min or so driving. [ I can make it go into 2nd if I rev it out to about 25-3000 rpm in first gear and back off the accelerator fast as it is going in to 2nd then it goes into gear. ] so I tried putting in a new dual linear solenoid - had slight improvement but still slips in 2nd gear or will not go into 2nd gear without backing off accelerator. I also checked the other solenoids which seem ok.
