trying to get advise on 2005 h2 transmission ! initially the box would shift fine in manual but not at all in d and it was very slugish on pull away as if it was sticking in top then last week the trans let go big style locking in gear ! i have just replaced the transmission and am somewhat disturbed to find it also isn`t shifting in auto but is fine manually it is setting dtc`s for torque converter clutch,shift solenoid a+b and shift timing solenoid i have checked appropriate fuses and pink wire to box and all ok also stripped back loom from box to pcm and there is no sign of damage unfortunately i don`t have a local authorised dealer so any help would be great

who rebuilt the trans ? or did you put a junk yard trans in ? if you had it rebuilt and installed by a shop ,bring it back and tell hem to fix it . if you installed it unplug every eletrical conection and clean them with eletric parts cleaner and put some dieletric grease on them and reconect them . some times it is as simple as that .

ignition switch, orig trans most likely ok(unless you got it hot by taking off in 3rd)

sorry its taken so long to get back but you were quite correct it was the ignition switch replaced it and been fine ever since thank you chaps
