hello everyone, lately my tranny's been struggling to shift. For example, I'll pull it in reverse and then i'll drop in in D4 or D3 and when I press the accelerate it kinda stutters for a bit. The other day it was kinda weird cuz i revved my engine to redline to let this girl know i was there to pick her up and when I shifted from park to drive and tapped the gas pedal, (i'm guessing) the tranny still hadnt engaged and it stuttered and shook a bit. Any ideas?
