Torque Converter Random Unlocking,47RE
So it started saturday on a cold 5 degree morning taking off from my parking spot, and my truck gets to about 1600rpm in 1st gear (where it normally shifts) than it all of a sudden the Converter totally unlocks and smacks back into gear, almost felt like it was spinning on the ice, than getting back onto traction. This happaned twice right after taking off from stop lights, and does it quite periodically. So I already know the trans and especially the Converter is weak, but before i let it get worse and bite the bullet for a built trans, could it be a sensor of some sort thats causing it to let loose? I had a speed sensor go bad that was causing it to shift, lock, and unlock the converter, basically at random, but replaced it and all was fine till now.

Well if the TC isn't supposed to lock than what is it causing my motor to basically free spin in first and 2nd. it does it at 1500 RPM in first. Ill be driving and it will almost always let loose around 1500 and spin up to 2100 or so than slam back into gear. Than in 2nd, if i am taking a turn and getting back on the pedal it will free spin worse and sometimes doesnt re engage till it shifts the transmission down to first. It doesnt feel like its jumping between gears. once it gets up to thirsd its solid like it always has been.
