SS Auto
 

Hi guys:

I own 4 HHRs, but not an SS so I am not too familiar with them.

I have a friend looking at a 2010 HHR SS Automatic with 140K miles and he had some questions.

1) As I understand it from searching the SS forum, the SS automatic engine can be brought up to the power of the SS manual with just a tune, is that correct?

2) The tune mentioned above would have minimal effect on the trans life? Obviously it must have some effect otherwise chevy wouldn't have reduced the power?

Thanks
Steve

1:yes
2: will be fine. 4t45e transmission is very durable.

Thanks!
I will pass the info to him.

FYI. A "tune" depended on which one, is most likely going to give you more power than the stock manual SS. There isn't a lot of difference between the stock numbers of manual vs standard. 235/250hp (235 in lower gears or something) vs the 260hp in the manual.
The SS auto trans is generally considered strong enough to handle around 350 hp or so.
