So, I had all the latest TSBs done, and my RL is into Acura for a manual shift mode problem at 5000+ rpms. The tech couldn't reproduce it (mainly because you have to do 80+mph in 3rd gear) so I had to demo it for him while he rode in passenger seat. Seems that the TSB to fix the upshifting into 4th gear from 3rd, does not fix the problem in it's entirety. My car is now there overnight, and I'm waiting to hear back from the tech about the issue. Is anyone else still having this problem? I've noticed that it doesn't happen every single time over 5000 rpms, but it is more often than not.
