For the first couple months, when the transmission was cold, it would be lazy about going into high range. Eventually it fixed itself

Thanks, I am hoping it doesn't come down to that but I will be re-sealing the range cylinder this weekend. I changed the oil this week to 75w90 and added some air tool oil to the HR air line at the cylinder. Is doing it less but still 1 or 2 times a day. I hope this works because if not AUX has to come out.
