It could help if you performed a clutch learn using Forscan while the transmission is fully warmed up.
If you don't have Forscan, it's free to download. Put it on a laptop then all you need is an OBD/USB adapter, good ones can be had for about $50 on ebay. Did you make sure to follow the correct procedure when changing the transmission oil? If not the front compartment could be low on oil, which would result in loss of hydraulic pressure on the clutch and shift actuators. There's videos on YouTube on how to do it.

I found it drove not smoothly when I got it, then changed fluid according to the YT or manual. then it drives very smotthy, no shuddder or hesitation. then this happens, when I was waiting for redlight on uphill, it shift into neutral, pressed gas again, it drove normally. |

Sounds like it's low on oil.

I have double checked the level, also just fluashed again.
Added 6.5L fluid into the fill hole under the airbox. It'a not the low fluid. I hightly doubt it's solenoid, that's why it's playing up when it's hot, normally after driving around for 2 minutes. It's butterly smooth when it's cold. Net step is remove the valvle body and clean those solenoids |

Get Forscan & get transmission up to running temp(when it's having the issue)u will be able to manually command/test the solenoids to confirm what u are thinking.

Removed the TCM and cleaned seninods, changed fluid again.
REmained same prob. Then I removed cooler and flushed coolant, looks like it never been changed before.also oil cooler is half blocked, removed filter housing and two pipes, cleaned and blowed dry. Then I can feel the oil flowing inside the pipes. Took it for 40 minutes spin, no prob whatever. It shifts gears very quickly. It's the oil cooler blocked!!! |

My Volkswagen Golf used to slip into neutral. For my car , I had to get a new Mechatronic unit.
