I need some info on the manual transmission in the Cobalt and Ion.

I see it is a F35, RPO code MU3.

This transmission seems to come from the F25 in Europe. Will parts from the F25 interchange to this F35?

I have found that Quaife has a LSD for the F25 and a 6 speed upgrade.

I have a webpage setup for manual transmission ratios, and general specifications if anyone is interested in this.

last thing i want on my car is a 6 speed. the gearing is far enough off as it is

The transmission ratios I am looking for are for much larger engines. I am putting the F35 from the Ion and Cobalt to 3800 SuperCharged and LS1 engines.

The F25 has an upgrade option that gives it a 47 MPH in first gear. You will need alot of torque to use this however. The F35 appears to be the same transmission from the F25 European models. The Quaife LSD is the same part number.
