Picked up a 5 speed at the local auto wreckers today,was told it came out of a HHr .Anyway to tell visually that it is and not a cobalt tranny

donbrew

Is there a tag on it? Any numbers?

What model HHR are we talking about? The SS might have 1 of 2 possibilities.

firemangeorge

They both use the same F23 5 speed transmission. Visually they will look the same.
SS's had the F35 Saab built 5 speed.

Reason for asking is its going in a cobalt but i want the final drive ratio that the hhr has .Only numbers I can see are 61dxw 06024746 looks like a bar code .Btw its race car.

firemangeorge

Gonna depend on the year. I recall some different ratios that were available in some of the earlier years.

FYI. I looked up complete units for the 2010 HHR and Cobalt. Show the same part number so they would have the same gear ratios.

Look through this thread, post #9. Only year I see that ratio is 2007. RPO code FR8.

The difference might be the differential?

FR8 is also listed in the 2008 list. It does not show for later years. It is likely in the 2006 as well but I do not see a list for 2006.

Op have you looked for numbers on the tranny close the the transaxles?

Thanks for all the help,went out this Am got the stock number that the Auto wreckers marked on it crossed referenced it on their web site and it shows it being out of a 06 hhr .So from what I have found on the internet it has the 4.17 final drive.
