Possible Transmission Issue?

[HWMOldster]

At just before 8000 miles, I was accelerating on an on-ramp to the highway. Maybe half-throttle in Normal. It went to shift and the RPMs surged in obvious neutral. I got off the gas—it came back down and went into gear. I couldn’t replicate it.

Brought it in to Toyota. No current codes. They couldn’t replicate it. But they did pull codes and made the attached notes. They said to keep driving like normal and to report if anything else happens while they speak with people above them about the codes.

Thoughts?

Recently change the air filter? Sounds like debris interfering with the MAF.

Nope. Bone stock as it left the dealership.

Hmmm. I'll be curious to see if the dealership comes back with anything

Toyota still had no news for me. Cruiser is driving great. But another guy on the Facebook group who had the same issue as me is having to replace his transmission. Not exactly inspiring...

At least your dealer didn’t blow you off, and tell you everything was okay…

Interesting..... My Honda Africa Twin motorcycle has a torque limiter on it and when the RPM gets to high it just revs and feels like neutral. It only happens when you rev too high as it hits the torque and rev limiter until you switch gears.

The code pulled from the toyota dealer says it reached Torque limit (transmission protection). Curious if this is something similar. But the transmission is done automatically and out of our control?

I was 1/2 throttle and nowhere approaching the rev limiter. It naturally shifted out of gear like it was about to go up one, but it instead went out of gear and revved without resistance (so neutral). So that code is very confusing to me.
