i would like to find a source where to get part #1 in the schematic. https://www.moparpartsgiant.com/part...t_control.html
i think it is the most likely to be creating the problem of gears shifting hard.
problem is, the part is no longer available. you have to buy the whole thing for about $1000.
there is (was) 1 available somewhere in russia but is not sure that i may get it.
