98 tj has case of the shutters in 1st gear

My jeep was starting to need a new clutch, so we went ahead and replaced it.
We get it back from the shop, and almost every time I go from a dead stop to rolling in 1st gear, the whole vehicle shutters including the shifter.. MOST solutions to this problem are to get a new clutch or flywheel or pressure plate, but since I just got a new clutch, and it didn't shutter before, should I take it back to the shop and tell him to fix it?

They probably resurfaced the flywheel, which is a big no-no on Jeeps. The flywheel surface is very slightly "domed", which helps it engage smoothly. If it is machined flat (which most shops do at a clutch replacement), it will try to grab all at once when it's let out. This makes the jeep shudder or lurch when taking off in first.

On the plus side, it's clearly printed in the FSM not to machine the flywheel, so the shop just bought you a new one!

Mine only shutters sometimes and others it doesn't. Is this the same situation? Wouldn't it do this all the time if that were the case?

Il go and drive it around for an hour or so and see if it starts to go away. If not, I'm bringing it back to the shop.

This and make sure all of the tranny mounts are in check.

This is kinda what I thought mine would be. Mine only does it periodically. Not all the time. I'd assume if the clutch and/or flywheel were bad it'd do it all the time. Any thoughts on that anyone?
