My 1994 1500 4x4 dose not seem to be shifting into over drive. Other than that it shifts fine. The fluid and filter have recently been changed I have adjusted the t.v. cable with no luck and it is not throwing any trouble codes. Some one said it might be the torque converter but I'm hoping it will be something that doesn't involve removing the tyranny because I live in the northeast and don't have a garage to work in.....So any ideas?
