Hey everyone,

So I have a 2010 G37X 7AT and it has been very good to me. As of yesterday if I try to WOT once the rpms get close to the rdine the car bucks and then starts shifting all weird like it has no idea what it's doing.

once i slow down it bucks upshifting into 2nd and 3rd and then doesnt shift 4th.

no check engine light or any lights in the dash.

Once i shut the car off and wait 30 seconds when j turn it back on everything is fine! Everything stays fine until I bring the rpms up near the redline again and this all starts over again.

Anyone have this happen before??

Thanks!

Have any of the transmission TSBs been applied?

I've had the car now for a little over 2 years. I haven't personally brought it in for any and I wasnt told by the previous owner if any were done either.

the car ran 100% fine until 2 days ago, so i wasnt sure if a TSB would be the culprit and thought there would be something else at play here.

if it was missing a TSB wouldn't this have been something that always happened and not just show up randomly?

thanks for your help!
