Where's the shift knobs?

[ScottsGT]

I'm almost wondering if a weighted shift knob would help the shift thuds these cars have.

Probably quite the opposite. Talk to a trans guy. One of the first things they will tell you is do not drive around with your hand on the shifter. The added weight puts stress on the syncros. Yea, it's hard to do in the '15.

I've heard this before and I feel like its aimed at old cars. I don't think cars now a days are that weak. The trans can handle 400 ft/lbs of torque and 435 hp but cant take a lb of pressure on the shifter assembly? lol. I've seen my father constantly rest his hand on his Subaru shifter assembly and almost 300k miles later its still fine not even a clutch replacement yet. These transmissions are exactly cream of the crop either.

Its a different kind of pressure. Engine torque is on the gears. Shifter torque is on the syncros. Not sure what the new ones are made of, but older trans' had brass syncros.
Trust me, a syncro will not handle 400 ft/lbs of torque or 435 HP if it was on the receiving end.
I too have put thousands of miles on older cars resting my hand on the shifter. It's not like I'm going to be able to change my driving habits at 52 years of age......

Having your hand on the shifter wouldn't have much of an effect on the synchros. I suppose a bit of axial load on the keys and blocker/cones but a fraction of what occurs during the shift itself or from the movement of the sleeve. The torque for a moment is transmitted by the synchro but it is the sleeve/gear/hub connection that transmits the torque.

The bigger issue is the fork will get pushed into the sleeve when you lean on the shifter. Typically there are vespel pads to reduce the drag and it would be these that get "worn down" but you would have to put a lot of pressure in the shifter to actually cause any wear.

Exactly. Like I said, thousands of miles, no problem. Tony of Astro Performance was the one that told me this when we bought one of his A-5's for my son's '95GT.
