well, my aw-4 isnt going into overdrive. i'll try to explain it the best i can
It shifts fine from 1-3. It does go into overdrive, but its revving higher than before. If you leave it in "3" it will shift the three gears and stay in 3rd which is obviously normal. well if i shift into "OD" it will drop rpm's but only about 200. before i parked it over the winter, it would run around 1900 rpms at 60, with my 33s and 4.10 gears. now its up to 2300 at 60. I'm thinking its the torque converter not locking all the way. anyone else ever exprience this or have an answer.
