uh hell no!?! you NEVER rev up an automatic then shift her into any gear. you'll blow the tranny or anything inside there. i had a 2002 prairie 300. always shifted fine for me. Honestly, i think it might just be the reverse gear inside the tranny :[
when did this all start? Did you ever hear anything before when it worked when you shifted it into reverse?
and seriously, dont EVER rev up an automatic then shift it. Only way you can shift while in motion is if your in high gear or low gear. If your in either one of those gears you can ONLY shift it into neutral. Thats the only time you can shift if you rev it or are in motion.
