So, last week I was driving the car and went around a turn and the tires spun a little but I was on the gas kind of hard, it banged into second gear and I drove with no issues. A few hours later I was going straight and I got on the gas normal from a dead start and heard a similar bang into second this time it kept hanging in first unless I took my foot off the gas or gave it more gas and then shifted around 4500 RPM, it drives fine through 2-3 and 3-4. So at the recommendation of J I changed the throttle position sensor and the throttle body gasket (cause I broke it) and it still has the sticking in first but when it comes out into second it almost faintly sounds like a belt squeal. It changes hard like if I have the performance chip setting on hard shifts. Do I need a 98 Transmission or should I take the chip out and see if that changes? Or is it inevitable. The fluid looks good and is full. Is it Mercon V, I don't know and I don't want to hear it, I haven't gotten around to changing it to be sure. The car has like 64k miles on it and is a 97 LSC. Thanks
