According to the factory service manuals all auto Cobalts have the 4T45E version. Don't know the difference....

LS/LT 2.2 autos have 3.63:1 final drive ratio (38/34 tooth chain drive, 3.05 gearing)
SS 2.4 autos have 3.91:1 final drive ratio (38/34 tooth chain drive, 3.29 gearing)

How much power can the 05 LS auto tranny hold? Is it a reliable trans?

Hypothetically say I have the Auto and want a Manual. I don't care if it's a Cobalt tranny or not, i just want a Manual. Anybody done a swap or know where there's a write up on one?

Not worth the effort...obviously it can be done physically since the Cobalt comes with both. You would need to redo the computers and wiring (this is the part that is not easy to do unless you have a COMPLETE donor car), R+R all the shift mechanisms, add clutch hardware/system, replace the engine mount/tranny mounts, and replace the Exhaust Downpipe.

The reason i want to put a manual in is because the acceleration sucks. How can i fix that since a tranny swap is out of the question for my budget, time and skill level?
