Hi guys,
So i posted a while back about the trans staying too cold which i solved. I’ve noticed as of recently when the trans shifts into 4th gear from 2nd with slow acceleration that the rpms will jump up and down while slowly accelerating in 4th. It does it in 5th too. and you can hear it and feel it but it’s not crazy bad and it doesn’t do it all the time.
I also noticed that when it happens and if i put it in tow haul mode that it goes away instantly. trans doesn’t downshift or anything it’ll stay in the current gear but it’ll just stop surging immediately. Rpms only jump up and down maybe 100-200 rpms and it doesn’t happen when you’re at cruise at 55.
Also noticed that there’s a very bizarre feeling when passing someone in 2nd. as soon as it hits 4k rpm it feels like you let off the gas even though you’re still wide open and then it picks up again a few seconds after. Any help? there are also no codes.
