Engine/Transmission (1998.5 - 2002) truck bucking

[Mike C]

anyone exp any bucking or shaking when driving down the road. seems to happen the most when in overdrive and on the go pedal. seems to be worse when cold and around 1800-2000rpm. im running dd2s ,edge ez,dtt transmission 4' exhaust. any help would be great

Sounds kinda like your torque convertor is trying to slip. You might want it checked by your local installer just to be safe.
