TMCC only goes full speed

Hi there

i have a 3rd rail/sunset loco with tmcc.

in conventional operation speed control is perfect

however, once connected to the legacy controller and operated in cab-1 mode, at the first click of the knob it immediately goes to full power.

Am I missing something with the setup or is the speed control circuit on the tmcc board shot?

thx!
