So i've just recently developed a shudder when the truck shifts. I'm not sure why. Its just started and I dont notice it when the converter locks up. Any idea's? Anything to check? Bone stock never seen a tune. Thanks.

Anyone have anything? Its driving me crazy! I searched and found someone with the same issues but they found it to be a motor mount. I checked mine and they are fine. I'm really not sure whats going on. Has 135,000 on the ticker. Just serviced and changed to a deep pan with new internal and spin on filters.

U joints are good, I checked them this morning. It doesnt shudder at all after it shits, its just right before it shifts. Doesnt matter WOT or 1/4 throttle... it does it. I have no idea... guess i'll let it ride and see what happens.
