2012 JKU Rubi, Manual trans ckunk...?

Hi all, hope I can get some light shed on this... 2012 JKU Rubi with 2158 miles on it, and when shifting from first to second, and then second to third there is an obvious double clunk sound. I can feel it in the pedals and in the floor. From a stop, clutch down rolling start in second, clutch down and shift to third, clutch engages and "Clunk clunk" rolling in third. Ive been doperating manual transmissions for 15 years so I feel like I know what I am doing. Speed and terrain are not a factor - happens low RPM, high RPM, street, trails. Seems to be intermitten. Placed a call to the dealer today, they said it was normal. Dont know if I buy that... Any help for a new member?

Ours does that occasionally too if my clutch work isn't perfect. The problem is the clutch. It sucks and has no feel whatsoever. When you push the pedal down you can't tell if it's engaged or not other than the pedal being all the way up or on the floor.

Normal . I don't get any clunk. six speed with 3200 miles. np. i think i'd take it to them and ask them to take a ride with you or let you drive one of the other six speeds on the lot to compare.

Are you sure its coming from the clutch and not a U-joint or an engine mount?

Driven a jeep before?

Steering components have play and will make noise if not shifting smooth.

My Yj, Tj and Jk all do it.
