lock up convertor?

Don't know much about lock up vs non lockup, or much else about them other than stall speeds...lol. But my question is this...I had checked our 1995 GT a few times and at 50mph I was turning 2500 RPM in 3rd (1:1). At 60 I was turning 3000. Today it seemed like it was winding harder so checked it and it was about 300 RPM higher at each speed. Would this be caused by the convertor being locked or maybe unlocked? Common thing? Didn't cause any issues, just curious. I did pull out from a light a little hard and after that it went back to the readings I had got before

Most likely the torque converter was unlocked this time. It only locks under certain conditions.

I was on a 4 lane but speeds were at about 55. Like I said, everything seemed ok, just wanted to be sure there were no issues I need to watch for

You should be good. Things like the ac compressor cycling or tapping the brakes can cause the torque converter to unlock. Even at cruising speed it’ll lock and unlock.

Well I did have the AC on. Have never ran it before today.

Thanks!
