I recently went to the stealership to have my transmission looked at...ended up replacing the tranny, shifter, clutch, and flywheel. Now the jeep shifts great but the whole rig shakes pretty bad when I get near 3200 rpms. stationary, while accelerating, clutch in, clutch out, in every gear. feels pretty nasty under the clutch pedal and in the shifter itself. only thing that came to mind to check first was the harmonic balancer...but it looks pretty good still. any ideas what it could be?
