Wanted to clarify some info on the ME2 vs MH3 transmission, I'm not stating the following is 'TRUE', but asking:

MH3, 2009/10/11, standard ZR1 'close ration' transmision

ME2, 2012/2013, standard ZR1 transmission, MH3 being optional

This is where the ME3 being an option threw me off, looking at the ZR1 order sheet, the ME2 'appears' to be the optional trans, of course GM has made some mistakes over the years with RPO's vs the order sheets

ME2
1st - 2.26
2nd - 1.58
3rd - 1.18

MH3
1st - 2.29
2nd- 1.61
3rd - 1.21
4th - 1.00

Thanks very much

Correct. The mh3 trans is included in the optional PDE high performance package available in the zr1

So can anyone provide a part# to order the MH3 transmission?

I found the following 2 part numbers:

24258818 - w/ skip shift
24258819 - w/o skip shift

Anyone know what the difference is? Both claim to be MH3...

I just bought a 24258818 and it was the recommended one from all the research I had found. Pace Performance had the best price plus free shipping last month so it was a no brainer.
