Does anybody know if there is some kind of separate transmission brain in a 95 STS? My tranny was shifting crazy hard (already had the solenoids changed) sometimes almost spinning free, brought to a tranny shop, they reset something, it stayed good for about 2 weeks, acted up again, so i disconnected the battery for about an hour now it's good again but am afraid to go on any long distance trips. 127,000 miles on car. any help would be appreciated
Thanks
