Torque Converter

Have a '98 Grand Cherokee 5.9 stock 46RE trans and replaced the solenoid, valve and sensor because it threw a code. My question is, would a bad torque converter still allow me to run through all the gears? It seems to shift fine (I think) but I seem to have one hellofa rotational vibration at about 1900-2200 RPM but seems to smooth out from there.

At that RPM, I would inspect the motor and trans mounts.

With 232,000 on the odometer, those were replace 32.000 miles ago but I'll check the torque on all the mounts. Any other thoughts out there? My thinking (& I could be wrong) but if my torque converter were bad, I wouldn't feel it shifting 1st through 2nd, 2nd though 3rd and then into OD?

Your transmission would have erratic shifting and jerking if your tc was causing a vibration check all mounts bell housing bolts tc bolts and driveshaft ujoints

Thanks people. I'm going to take a closer look at the drive shaft U-joints. Would low levels of fluid in the transfer case and front differential cause vibrations?
