I need a transmission guy near London

So my 2011 threw a P2757 code. I called a couple places and ended up taking in to somerset Toyota. They charged me to tell me it was a P2757 code. I ended up taking it to a transmission shop near Corbin. They took it apart, checked all the solenoids, changed the fluid and said I was good. Paid them and left. Light came back on the way home. I have just been clearing it a couple times a day. Transmission feels fine and I have no symptoms but want this fixed whatever it is. Any recommendations?

 

I would take it back to the transmission shop and tell them to fix your junk for real this time. You said no leaks so it has to be internal, yeah? Quick reading shows general consensus is have a pro fix it (apparently twice in your case).

Good luck
