Hello All, new to the site. Question for the trans experts. Recently had my th400 rebuilt. The kick down switch did not work, it was gas pedal type and we could not find one in town. So trans shop bypassed the switch somehow and it worked fine for a bit, but now truck shifts fine 1,2 and 3 no issue but will not kick out and revs high in 3rd and truck does not down shift. Any ideas on possible issues?? Thanks in advance. J
