Manual Transmission Swap

[not_so_supersonic]

Hey guys I've got a 2012 sonic hatchback 1.8L with the auto transmission. The transmission is shifting rough and despite my best efforts I think it may be near the end of its life. I've found a 2011 cruze with a manual trans as a donor vehicle does the manual trans from a cruze fit our Sonics? Other than clutch cylinders, cv axles, and wiring. is there anything else I would need to consider?

Hey dude, so there are 3 choices for your sonic.
1)Source a 6t40 trans from a 2014+ cruze/sonic and reflash the 6t40 tcm to accept the 1.8L ECU to communicate properly
2)buy the update 6t30 valve body kit to reroute trans fluid flow. Buy on either rockauto or amazon( $195)
3)do a M32 6 spd manual swap...you will need a donor car. Thing to note when connecting the M32 T76 transmission control module is you will need to have the factory 1.8L E78 ECU reflashed to accept the manual transmission. Everything is connected by a CAN network and the Original VIN is encoded to all the control modules in the car...a full reflash with the original 1.8L ecu vin to the M32 TCU will fix the compatibility issue. Hope this helps dude.
