Chevy Cobalt SS Trans

[nugz]

GM F35

Specifications

Type: transverse front wheel drive, five speed manual transaxle.

Engine Range: 2.0L

Max Gearbox Torque: 258 lb.-ft.

Weight: 99 lbs.

Applications: Chevrolet Cobalt SS, Chevrolet HHR SS



The F35 is a Saab-designed five-speed manual transaxle built in Saab’s Gothenburg, Sweden, powertrain plant. This extensively tested manual transmission was originally introduced in the 1984 Saab 9000, and today it is used in the Saab 9-3 and 9-5, Chevrolet Cobalt SS and on various Opel applications.

The F35 features a two-axis conventional transverse layout, fully synchronized gears, and compact packaging. It features higher torque carrying capacity than many other manual transaxles currently in use in North American small cars.

Different versions of the transaxle are available, depending upon application. Both cable and rod shift mechanisms are available, as well as application-specific clutch housings.

Design features include triple-cone synchronizers on 1st and 2nd gears, and single-cone synchronizers for 3rd, 4th, 5th and reverse gears.

A limited-slip differential is available for high-output applications. This torque-sensing differential is an all-mechanical geared unit that uses no clutch packs or preloading to transfer torque from one axle to the other, and torque transfer occurs automatically when one wheel loses traction. Torque transfer also occurs gradually, without steps.

So what would I need to do to take the threshhold beyond 258 lbs of torque? Get the lsd? and if so where can I get one?

if i am upgrading my power band upwards of around 320hp does that mean i am going to have to upgrade the gearbox too?!
