INTRODUCING THE JHM PERFORMANCE 0A3 TRANSMISSION REBUILD KIT!

JHM Performance Carbon Synchros:

We have been testing and abusing our JHM Performance Carbon Synchros for the 0A3 Transmission since 2013 in our Supercharged S4 and RS4s. We have been putting them to the ultimate test to make sure they can handle all the abuse we throw at them. We have improved upon the OEM Design featuring an improved coefficient of friction VS OEM which will result in better high RPM shifting. Our oiling grooves will provide better cooling to the synchros increasing the durability making them longer lasting. Best of all, they cost less than OEM synchros making these an incredible bang for your buck.

Fits all 0A3 transmissions found in the B6-B7 S4.

Is your transmission going bad? Do you have synchro issues and gear crunching? Do you have trouble getting into gear? Is your shifter randomly popping out of gear? If you want to fix your transmission issues right the first time then this is the rebuild kit for you!

Our FULL 0A3 Rebuild Kit INCLUDES THE FOLLOWING:
- JHM-Performance 3-piece Synchronizer rings (6)
- OEM, UPDATED 1-2 Shift Collar or Synchro Hub
- OEM, UPDATED 2nd Gear
- OEM Input Shaft Seal
- OEM Input Shaft Seal C-Clip
- OEM Input Round Seal or O-Ring
- OEM Selector Shaft Seal
- OEM Front Output Shaft Seals (2)
- OEM Rear Differential O-Ring Seal
- OEM Selector Shaft O-Ring Seal
- OEM Front Diff O-ring
- OEM Selector Shaft Detents (2). Even though these detents are reusable we include them for several reasons. It's best to replace the two detents at the selector shaft. Also, on some early 2004 S4s there was a reverse lockout issue and these updated detents fix that issue. Finally, sometimes these detents get damaged upon removal so it is good to have replacements when doing a rebuild.
- OEM Rear Output Shaft Seal

If you've got "crunching" while shifting or any of the symptoms described above, do not push the rebuild down the road and increase your costs when you finally rebuild the transmission. Look what happens to gears and collars when the symptoms are ignored:

**NOTE: This is our FULL rebuild kit with all of the parts required to fix the faulty 1-2 Shift Collar AND 2nd Gear. If you are interested in our MINIMAL Kit or our 2nd GEAR REPAIR Kit, please go back to the "Shifters, Trans, and Drivetrain" Section and select either of those kits.

OPTIONS: If you do not need the complete kit or need just the parts to make a repair please email for pricing. We do not offer them separate without talking to our customers. We want to speak with you and make sure you get exactly what you need.

The retail price on these from a dealer as of 8-1-2012 is over $2000 if you can get them to help you pick out rebuild parts and not just try to sell you a complete transmission. So you save almost $400 by going with our Rebuild Kit. If you are NOT in CA you will save on tax as well.

NOTE: Kits usually ship out from our location within 1 to 4 days depending on our current stock.

We also provide this rebuild service here at our shop in Lathrop, CA. Please contact us at to get an estimate for your rebuild.
