Well its starting to happen to my 2012 Boss with 12500 miles. Becoming difficult to shift 1-2,3-4 at higher rpm. So I'm looking for advice on the fix. I've read upgrading the shifter, clutch and associated parts should help. My boss is all stock and I am a spirited driver and may never track the car. Exactly what parts work best for a stock boss driven on the street? Thanks all.

Sounds like a misadjustment, many have gone with the shifter upgrade. Have not done this myself but others will answer here. I'd be concerned about wrecking the transmission if continuing to miss shifts.

New clutch with flywheel and MGW shifter along with fluid change is a home run for the way you state you drive your Boss. As long as the MT82 is not damaged from the missed shifts.

Agree.

Fixed my shifting & lockout problem.

Thanks for the feedback. I'm thinking for my driving, the Spec Stage 1 should be fine along with the upgraded shifter.

Agree. Do keep an eye on the tranny. Syncros May have taken a beating.

Any thoughts on exactly which clutch? Want stock/close to stock pedal feel for a spirited drive. Very little if any track time. Maybe some autocross someday

I'm a McLeod fan all the way. The RST is a great upgrade for stock/mildly modified cars. Clutch feel is as easy or easier than stock. Aluminum or lightened steel flywheel is a wise upgrade while you're in there, IMO.

I currently run McLeod RXT with aluminum flywheel, love it. Lighter than stock feel and strong. Might be a bit a excessive for stock upgrade, but RST is my vote for you. Lots of sales on still now, I know lethal performance has 5% off in December I think.

I went with the SPEC 2+ with lightened steel flywheel. If your not tracking the car, perhaps a SPEC 1 or 2 would be best for you. These are a bit firm until broken in but with certainly help keep down NVH since you're mostly streeting the car. The 2 and 2+ work better with higher torque. Twin clutches have a tendency to chatter as does the aluminum flywheel. Lotsa of good choices out there. The above mentioned RST (Street) and RXT (Track) by McLeod are great clutches as well but have been known to bring some NVH. 

 

@WHO DA - you hearing anything with your setup?

Just the smallest bit of chatter under load with low rpms. (Crawling around a parking spot or pulling in the garage). Nothing during driving, it’s soft, tame and holds like hell!

Thanks all. I will take a look at the McLeod clutches too.
