If you want to fix it right the first time, completely reseal your transmission, and have all new JHM PERFORMANCE CARBON synchros and our JHM UPDATED 1-2 Shift Collar, then this is the rebuild kit for you.

We developed our JHM Updated 1-2 Shift Collar and our JHM Performance Carbon Synchros based on the demands of testing and abusing the 01E Transmission since early 2007. Prior to the release of our JHM Performance Carbon Synchros, we started long term testing on our JHM Updated 1-2 Shift Collar. In typical JHM fashion, we installed this 1-2 collar on our record setting B5-S4 and put it through miles and miles of hard launches, high rpm 1-2 shifts, and general abuse and the collar has performed exceptionally. We have also put the JHM Updated 1-2 Collar through rigorous long term testing driving it for miles installed on our shop B5-S4 along with several other cars for thousands of miles.

INCLUDES THE FOLLOWING:

• - JHM PERFORMANCE CARBON updated 1 and 2 synchronizer rings only.
• - OEM synchronizer springs (2)
• - JHM Updated 1-2 Shift Collar (Outer collar only; the inner collar never fails. If yours is locked up, just press it apart and install it in the JHM Updated Collar.) The outer collar is the part that causes 1st and/or 2nd gear to lock up when it fails.
• - OEM input shaft seal
• - OEM case gasket

*NOTE: Our JHM 1-2 Synchro is a direct replacement for OEM PN 012-311-247-H and only works correctly with our JHM updated 1-2 collar (direct replacement for OEM PN 01E-311-239-L) or the OEM updated 1-2 Shift Collar (OEM PN 01E-311-239-L) with the updated engagement angle.*

*NOTE: This is a minimal repair kit ONLY to patch up your transmission and just fix the bad 1-2 shift collar and the 1st and 2nd gear synchros.*
