Re: E4OD TC will not lock up when cold

Thanks for the reply, as stated I have owned this truck for 15 years and this problem never existed until a couple of years ago. I live in central NC and it never gets real cold here.
You know, it's also possible that it's not a torque converter lock up problem at all. It may be that it's not going into overdrive until it warms up. What happens is I have to run about 2500 RPM to go 55 MPH and after it warms up I tach only about 1900 RPM's to go 55 MPH. The transmission shifts but it doesn't shift right.
What do you think??
