been going on now for the past month....since it REALLY got cold...-10 or so.
when I am cruising home...it will hold steady at 2K Rpms....it wont go into OD. I can see it shift into 4th.......but at 55 or so ....I can feel it shift into OD for a split second..then it kicks it out into 4th. I have to be going 65+ for the OD to really work and stay kicked in. I have found out that this may be the reason behind all my fuel consumption. its not staying in low RPm's one might say. it is a vacuum 4L60...
tranny man? 97 GP GT, 156,004 miles on it. no shift kit yet....
what would one do?
