About two weeks ago I replaced all of the fluids in my T with Royal Purple, including:Rear Diff, Tranny, and Oil. I also did the plugs, and serpentine belt. I just turned 65K on a 06 KC 2wd. I did the spill and fill on the tranny but did it 4 times, starting the vehicle and shifting gears between each time. In total I put 11.5 qts of RP in, obviously losing some during each spill. Now the issue...
About a week before I changed the fluid my tranny slipped between 3rd and 4th on an on ramp. I figured it was time to replace fluids. Now, my truck shifts awesome... 90% of the time. Within the past 2 days, my tranny will miss shift into 4th. It only seems to happen when the truck is at operating temps and on normal acceleration, with mixed coasting (back roads w/ lots of corners). I have found that it seems to do it when I am coasting and then give it gas. The RPM's raise without any, or very little, power to the wheels. I do not have any check lights on, so am not sure if its my tranny. Any help would be greatly appreciated. Also, I checked the fluid and it is in the middle of normal range, not full or low.
At this point I am thinking it could be my torque converter or transmission control module. Thanks in advance
