Torque converter unlocks at random?
I just got back from the airport, on the way down the tranny would unlock for no reason at 60-80mph in 4th. The rpms might climb 200 or 500. It would go from say 1600 to 2000-2200 and feel like it was slipping then lock back up. Did this on the way back but then quit for the last 40 miles.
Before exiting the interstate I went half throttle and it shifted to 3rd at 70 and the rpms went to 4K, stayed there and it didn't accelerate like normal. The rpms at 70 in 3rd should have started at around 3k.
Got back into town and it locked fine at 50-55. Is my tranny crapping out? This has me greatly confused.

Stock stall
This is not the first time. Happened when I went on a 1500 mile trip in the spring, did it maybe 3 times for a total of about 1 mile on the trip. Had a frost tune done before the trip.
Did it a couple times on a 20 mile trip a month ago, which was about a month after changing fluid/filter.

if its not a misfire i would log for pressure manifold operations and tcc lock up and possibly the harness too. I have seen many of these mess up but if it started after tune then prolly misfire
