When i am in OD, at 35-40mph (where i notice it most often) sometimes it feels like its bucking. it feels like the TC is locking and unlocking.. it bucks and chugs. its not lacking power and doesnt seem to be a misfire. when it is acting up, i am pulling more RPM at 35-40 rpm. my tune is setup to put me in OD at about 36-38 mph, that gives me around 1100-1300 rpm (vaguely) when its acting up, its closer to 1700RPM or so.. I havent studied it thoroughly enough to know exact RPM's. it will also feel like it is engine braking as well, like you are letting off the throttle in a low gear of a 5spd car. it does that sometimes at freeway speeds, but it doesnt buck, just engine brakes. when it is doing that, when i come to a stop it does buck some...

I am thinking TCC solenoid? It doesnt feel like it is hunting for a new gear, so MLPS isnt what i am thinking..

anyone else had this problem? what was your cure?

new plugs sounds alot easier than a new TCC :)
the fluid is a good percentage new. I put in a deep pan last year, and added 6-7 quarts new Merc V (i dont remember exactly how much it took)
