2015 M26(5speed) on 2012 5 Speed 1.8 and Flywheel options

[DSchmidt54]

Hello guys, I've been following the forum for a while now, and unfortunately, it's come time for me to post. After 143,xxx miles, my 2012 1.8 5 speed finally died. The Final drive in the transmission started grinding, and i pulled into my own front yard in 4th gear. Prior to that, trans was whining for about 100 miles real loud and I had no option but to keep pressing home.

Fast forward two months, I've finally located a trans near me. its a 5 speed out of the 2015 1.8 car and I bought it online because its 45 minutes from the shop where my car is at (dads shop). So my question. Every where i look, i find 2012-2013 and 2014-2015 being grouped when discussing these m26(f17) 5 speed transmissions. What are the differences between the two? will i need a different DMF? Here are my findings below, I would love it if someone can confirm or correct me.

RockAuto shows a 14 tooth spline on every Clutch kit for the 1.8 from 2012 -2015 and shows a LUK DMF133 flywheel for 2013-2015s

HOWEVER, RockAuto also shows 3 different single mass flywheel options for all 1.8s from 2012-2015. Most common is the ACDELCO 55587031 or PLATINUM DRIVELINE FW808.

Now to compare, the 1.4 MT in 2015 shows a 20 spline kit and only Dual mass flywheels as an option for those engines, Again, Luk DMF133 and another similar from platinum driveline.

So my assumption is, If I have a 5 speed trans coming out of a 2015 1.8 going into a 2012 1.8 that also had the 5 speed, I should be good to just buy the 14 tooth splined clutch kit. And if i put a single mass flywheel on it, the car will drive better with the exception of more vibrations/touchier shifts.

Thanks in advance to anyone who can clear this up!

Ok, A lot of views, not a lot of comments. I'll follow up with my findings for anyone who is interested.

The 5 speed M26 transmission (f17) is 14 spline. You will need Flywheel 55587031, Friction Disk 93192580 and Pressure plate 55489045 From GMPartsgiant or the like. Most stealerships stock these at damn near double the prices due to availability being low. out the door, I got them for 199.47 before shipping.

NOW Believe the bell housing bolt pattern is the same on the m32. Just it runs a different spline and Master cyl part number so my guess is to swap over to the 6spd you would need the friction disk from the 6spd m32 paired with the flywheel and pressure plate for the 1.8 engine. if anyone has an old m32 friction disk lying around, it would be nice to compare. I personally prefer the displacement of my 1.8 NA but would like to get under 3k rpms at 70+mph

Additionally. Cross reference Rockauto for the slave master cylinder. I got mine off Amazon for $100.

All in all, the cost to do this transmission swap was $400 for a 11k mile 2015 m26 transmission, 225 to Gmpartsgiant for the clutch and flywheel, $140 to amazon for the master cyl and MT-90 Redline fluid.

So all in all, an $800 job if you count beer and shop supplies. Between my dad and I we did it in 8 hours with the car jacked up about 15" off the ground.

Hope this helps someone in a similar predicament.

Can I ask you how this went?

My 5-speed 2012 1.8L manual just blew and I am looking at a new Korean made replacement transmission on eBay that says it is for 5-speed 2013-2015 Sonics.

The seller's ad lists part number:
96664114

Past specifics about that ad, I'd really appreciate anything you learned more generally about the compatibility of these manual transmissions between years and possibly other models. I heard the Cruze may also use the same transmission for similar years?
