I have a 5r110 and when the converter locks and i lean on it a little i get a shudder. I know its in the drive train, almost feels like the engine cuts out but im almost positive that isnt it. Its not throwing anyt codes except for every so often i will get the throttle position sensor code. Also, I am getting a hesitation to shift into gear, as well as engaging and disengaging several times in reverse. Stock tranny with an ats converter. Anyone know whats goin on?
