A True Bolt-In 5-Speed For Your Mopar Is Coming Soon

Introducing the new A-855 from Passon Performance. For the last 15 years, Passon has emerged as the “go-to” company when it comes to Chrysler four-speed transmissions. Over the years, they have developed more innovations for the A-833 four-speed than anyone else. Now, they have done it again with their all-new five-speed gear box!

It’s the only five-speed transmission on the market that is a direct bolt-in replacement for the A-833 four-speed. There have been numerous other “off-the-shelf” five-speed transmissions that have been used by various companies to retrofit these modern transmissions into early Chrysler muscle cars. All of these have one thing in common: they do not fit. They all require either cutting the floor pan or adversely changing the driveline angle of the vehicle.

In some instances, these kits even require cutting into the structural torsion bar crossmember of your pride and joy; not to mention that you must modify or change things like clutches, bellhousings, driveshafts, shifter handles, or clutch linkages. It will be available for A, B, and E-Body Mopars. It weighs a mere 105lbs, and is said to be rated conservatively at 650 ft. lbs of torque. They are testing them now (we should say torturing them) and should be available by mid-summer 2011.
