MT82 transmission, why so troublesome??

A little history first. Back in 2005 Ford went to a remote mounted shifter in all manual trans mustangs, meaning the shifter is mounted to the underside of the trans tunnel then is connected thru linkage to the trans. When the engine torques over during hard acceleration the trans moves with it. Well the shifter is fixed and doesn't move so there is going to be bind on the linkage when this happens. It wasn't an issue back then, now fast forward to 2011 when Ford introduced the 412 hp coyote and the MT-82 trans. Now the remote mount shifter became an issue, not sure if it's the big jump in hp or the mt-82 that is the problem, I suspect its a little of both. From 2011 to 2017 the mt-82 had 5th gear as a 1:1 ratio or direct drive (all manual transmissions have this) in 2018 the mt-82 was redesigned and direct drive was moved to fourth gear and now 5th and 6th are now overdrives. They also started using cast aluminum for the shift forks inside the trans, previous years the used cast iron. Well the early 18 mt82's would break the shift forks because they were weak and i suspect that is what happened to your first trans and that is why they changed it out, no questions asked. Your second trans might have a misalignment issue with the shifter, if not it has an internal flaw.

When you finally get it back and they have a good trans in it look into a shifter support bracket from blowfish racing. https://lmr.com/item/SSB-15-000/mustang-blowfish-racing-shifter-bracket-1516-SSB-15-000 It bolts to the trans mount on the tail housing and moves with the trans, the the shifter bolts to it so now it moves with the engine and trans thus eliminating the binding issue and prolonging the life of the trans and shifter.

I just installed the Barton two post shifter bracket. Still have the OEM shifter box but it is a MASSIVE IMPROVEMENT over the ty squishy factory shifter mount ! Best $ 120 I've ever spent. Combined with the Steeda 34lbs. clutch assist spring the driving experiance is much improved !
