This may be a stupid question. When I test drove a 2013 JKU Sport with 6 speed manual, I noticed that there was a metallic clinking noise (very much like the sound of metal linkage) when I shifted, even if the clutch was pushed solid all the way to the floor and I was coasting pre-shift.
I found the same to be true in my JKU Rubicon, also 6 speed manual. This thing is brand new, about a month old. I've heard similar noises like when I had my old 1992 Toyota 4x2 (damn I miss that pickup *sniff*). With the Rubicon I noticed that the transition from 1st to 2nd is a little slower than the Sport just because of the gear ratio difference.
So my question is - is this clinking noise just part of the show and perfectly normal? It doesn't happen all the time and doesn't happen in the same gear transitions all the time (though it definitely happens more in the lower gears than the higher ones). Am I clutching wrong? (as I said, I've tried this with the clutch pushed through the floor and it's the same result as a lighter clutch and trying to match revs).
It's been a long time since I've driven a manual on a truck chassis so maybe I just forgot about noisy shifts and got used to the silent shifts in the BMW. Please let me know if this is just new Jeep paranoia or if I'm doing something wrong.
p.s. It's not a "grind", e.g. I'm not slipping or missing gears. It just makes a little metallic clinky noise pushing into the next gear or coming out of the current gear.
p.p.s Sometimes the noise is so faint I have to turn off the radio to hear it, but I can "feel" the difference when holding the shifter whether it was a noiseless or a noisy shift.
