Reverse only. No forward gears

I changed the tranny fluid and filter. Only drained about 2.5qts out of the pan. Replaced approx the same (the first time). First run and shifting was sluggish with the truck jerking into gear. Drove a mile or two and it cleared up. Parked it and the next day now I have no forward gears. Reverse only.

After the first "test run" I pulled codes P0761 and P2714 and P2757. I then drained the pan a second time and pulled all shift solenoids and bench tested with 12V. All actuated properly. 2013 Tundra. A760e trans.

 

Did you fill it correctly? I.E. get it up to the correct operating temp then check the level? Its only got a small window to do it in.

 

Yes. I put the truck in trans fluid temp check mode and made sure it only trickled out of overflow port.
