2009 Pilot ex-l with 133k.

Transmission works great in all conditions except the following:

When I am cruising and then slowing down for a light, as I slow down to 5-8 mph, if the light turns greet and I press the pedal to accelerate, the transmission slams\clunks into first gear to re-accelerate. This does not happen when I have OD off and drive in D3.

Just changed the fluid 1k miles ago, checked levels, are all good.

 

You could have a soliniod issue but most likely You have a stuck valve or clogged screens or tube best thing to do is overhaul with new converter
