Torque converter not locking up
so I was driving my 04 Silverado on the highway and i was trying to pass a car. I was going about 50ish and the converter was locked then all of a sudden it unlocked and has been unlocked ever since. The trucks mods are ms3 cam, tsps ls6 heads, prescion 3,800 stall. I've been checking for codes, I haven't came up with any codes. Prior to that I was in stop and go traffic. Could it be the brake position sensor? The truck seems to be shifting decently but it it likes to stay in a lower gear now and it lunges everywhere I go. As well at around 25mph it downshifts from second to first and revs up to about 4,000 and then takes off. Any help would be greatly appreciated.
