im looking to get a beefier tranny for my 2.2l ls automatic, blew my stock tranny. ive heard the 2.4l tranny will fit, is this true?

 

yes it should fit

 

its the same transmission

 

^x2

 

Thank you guys so much the beast will be running very shortly then. I'll post vids I'n about a month.

 

The 4T45E transmission is in both the 2.2 and the 2.4

 

the 2.4 tranny has a different gear ratio thats it

 

^^^ The auto's have the same gear ratios and final drive ratio in the 2.2 and 2.4 afaik. Same tranny in a G6 base model has a shorter final drive ratio, other applications have taller ratios.

To the op - you won't gain anything by pulling a tranny out of a 2.4 car, they are the same.
They really can handle some power - 200+ ft/lbs iirc.

If you can get one out of a G6 base model, they have a 3.91:1 final drive as opposed to the 3:63 as used in the Cobalt - little better acceleration but a little worse mileage
