What fluid is everyone using on their 727 torqueflites? For reasons I can’t remember when I resealed my transmission I put in full synthetic ATF+4. Issue I am having is that if I try to take a long trip, say over 20 miles the transmission starts acting up. It feels like it stays stuck in second gear and I really have to punch it to speed up past 30 mph. Only cause I can think is that the fluid when reaching a certain temperature causes the bands to slip.
