I have had some major issues somewhere in 5th-6th gear over the weekend. The truck would not lock into gear going up a decent incline at 60-70. It threw 2 codes and I deleted them and it did it 2 more times after that.
P0729: gear 6 incorrect ratio
P1507: crankcase filter restriction
my transmission started acting funny after putting my tunes on the truck. I’m running rays tunes with the mm3. Any advice would be greatly appreciated! The truck is a 2016 with 68RFE

i would set truck back to stock- and reload the tunes. Make sure voltage it good.
has CCV filter been done recently?
I have put it on the stock tune and it didn’t help. No it has not been changed. The truck has 34k miles. As far as stock emissions and exhaust haven’t tried that yet.
The tuning most likely has nothing to do with it. What you say "acting funny", was just the trans relearning. As for the incorrect ratio code, that's not good. Gonna eventually need some major work done. Take it as easy as you can. I limped a 5th gear incorrect ratio code for a couple years. Start looking at built transmissions.Quote:

Thanks for the advice. I’ve had 4 68RFE’s with trans tuning and never had one feel the way this one has once it was tuned. This one has the lowest miles on it and has been treated the easiest too.Quote:

Funny, it was my 3rd. All treated pretty equally. The first 2 were 373 gear with factory size tires and no problems at all. My third was 342 gear, and 35 inch tires. That's not a good combo for the overdrive clutches and any bit of added power. I'd just lock 6th out in your situation and run her as long she'll go.Quote:

yes I think that’s the problem. Probably just going to have to go to a different brand with a better transmission.Quote:
