2000 GT Bucking issue

[bepetro]

Anyone ever have a bucking issue while trying to maintain a constant speed?
The tack will spike up bit and the car will buck, if you let off it goes away, if you step on the gas it goes away. Car idles and runs good, it does not do it all the time. No lights are on, I have replace plugs, air filter, idle module, distributor module, gas filter. It does it at any constant speed, be it at 20 MPH or 65 MPH.

could be the transmission shifting in and out of convertor lock

Ok, can that be resolved?

you have to take it to a transmission shop that can check it for you

since we dont know what the problem is specifically no way of knowing the cost. The shop that you take it to can give you an estimate.
