New to the site, have a 2021 2500hd with 6.6 gas. Yesterday was turning around in my driveway and heard a bang, then check engine light, trac light, reduced engine power, service parking brake lights all came on. I can run through the gear shift, but it won't engage any gears. When I have it in r or d if I touch the gas it revs up and speedo keeps going up. Looked at shift linkage and it does move, so I'm guessing a serious internal trans issue?? Anyone else have an issue like this? Thank you , Update, just pulled code p215b , output shaft speed correlation

2001 gmc sierra crew cab bagged front and back, with c notch. on hard acceleration the oil cooler line on the transmission side keeps blowing out causing my fluid to go every where. When driving normally it’s fine but hard acceleration no. The metal clip on the transmission but the line blows out each time. And everytime I pull over, wait 15 minutes connect the line back and new fluid, and trans good if I drive nice and slow.
