Hello everyone. Let me just say what I plan to do with my car is very rare & is going to be unique. First of all I've got a 2009 Cobalt with 2.2l LAP & auto trans. I'm plan on keeping the auto tranny & swapping out the engine for a fully forged LSJ engine with pretty much every thing you can do done to it. I honestly dont want to have to do a tranny swap but I already have a JBP engine mount & was wondering will this work with an auto tranny? And does anyone know where I can get automatic tranny mounts? Or can I just use some poly mounts that the manual transmission would use. Any help would be great. Thanks.

 

It is much cheaper and more practical to fully forge and build the stock LAP engine than it is to swap a LSJ in its place. Also, the transmission is rated for 315ft-lbs of torque from the factory. If you plan on making some serious power, and think you will make more torque than that, then I would recommend building the stock 4t45e auo tranny as well. The 4t45 can take over 450whp with a build with ease.
I like being unique, but swapping an LSJ over is an electronic nightmare, as most sensors on the entire car will need to be swapped out. Building the LAP is a much more practical route.

TTR sells automatic transmission mounts fyi

 

HUGE waste of time and money. build the 2.2, alot less of a headache.
