Symptoms of a Torque Converter going out?
Ever since i got the truck i noticed that when downshifting from 6th to 5th i would start to hear and feel a grinding/shake for about a second right before the Transmission would shift. It really didn't bother me much because it only happened in that gear. But recently i have been noticing that as i come to a stop from low speeds (20-30mph) probably in third gear the truck would really give a rumbling feeling even once i completely stopped with my foot on the brake. I am wondering if this sounds like the locking clutch or something in the torque converter is going out.
Yes my truck is modded with a towing tune and Xtreme Street tune from IDP, though i do notice the issue with any of the tunes i run, even the standard SCT Tunes.
