Just out of curiosity, anybody seen the two side by side?
I keep looking at pics and despite different BMW part numbers, they look identical!
Asking because Im considering replacing the worn transmission mount on my F56 MCS Manual with the supposedly stronger GP3 mount (which only came in automatic).

Far as I can tell, it's plug and play but wondering if any Mini service techs or pro's in these forums would know?

 

I just outlined this in a thread with full details: Differences between GP3 & regular tranny mounts

 

Hey there! Good to hear from you again. Im asking specifically with regards to trans mounts for Manual cars vs Automatics, not GP3 (all automatics) vs MCS/JCW (auto and manual). More specifically, can I order the part number for the auto and use it in my manual equipped car? Are they identical and if so, why the heck are the part numbers even different??
If anyone has seen them side by side (like a Tech), then I guess we could know for certain. Oddly, the auto trans mounts are also generally $10-$15 cheaper for whatever reason.

 

There are parts number variations when they release a new iteration of a part, the next gen part comes with a new part number.

Having as much experience with details of the mounts as I do, I think you are overthinking what will end up being very minor differences that can be felt or identified from the drivers seat.

 

Lol, perhaps overthinking but not about feel, more about fit. It's a TON of work to replace these on manual cars (remove wheel well, battery tray, axle and axle support, etc) so I just want to be sure the part will fit and not have some random slight difference that causes a fit nightmare.

 

They will fit interchangeably- I have done it

That is why I have a brand new GP3 moiunt for sale... had 3 variations side-by-side and the stock one with the Powerflex was much stiffer than the GP3, which I require b/c I have a high HP car. But had each one of these mounts installed over the course of a long weekend when I rebuilt my gearbox and did a clutch upgrade, amongst a variety of other things
