shifting

Hey all, I've got a trans issue that I can't nail down. A few months ago, I changed trans fluid to the Ford XTM that people like for these cars, and I noticed a new hesitation to go into second gear. It's hard to explain exactly how it feels, especially since the feel changes, but it's a cruncy...

So I have a 06 ms6, basically stock minus a rmm and some suspension bits, I've been planning to do my trans and passenger mounts this week, but recently after just driving the car around town normally 3rd gear kinda felt like it didn't have a gate, it goes in smooth but there's this "pressure"...
