I noticed that in the stock transmission parameters the trans is set to got into limp mode at 235 degrees. But the O/D lock out is set at 270 degrees. Seems to me it ought to go into O/D lock out before in would go into limp mode (related to temperature). I adjusted the O/D off down to under the limp mode but I got locked out a couple times during normal driving in the summer. I am assuming the temps the ecm uses is in the line as my probe in the pan has never been over 190. I'm not sure I understand the logic of the stock programming here.
