01E 6-speed Full Rebuild Kit (JHM-Performance) w/ OEM Updated 1-2 Collar

If you want to fix it right the first time, completely reseal your transmission, and have all new JHM PERFORMANCE CARBON synchros, then this is the kit for you. (NOTE: Our 1-2 Synchro is a direct replacement for OEM PN 012-311-247-H and only works correctly with the OEM updated 1-2 collar PN 01E-311-239-L for the correct engagement angle. It will NOT work correctly with any other PN 1-2 shift collar.) (NOTE: Our 3-4-5-6 Synchro is a direct replacement for OEM PN 012-311-395-F and works with factory and replacement 3-4 and 5-6 collars.) We have designed these synchros based on our demands of over 6 years of testing and abusing the 01E Transmission. See below for more information on how our new JHM PERFORMANCE CARBON Synchros stack up to previous OEM synchos:

 

 

These JHM Performance Carbon Synchros were in the JHM B5-S4 during our record setting 10.8 second quarter mile pass in December of 2011:

 

 

We've been long term testing these JHM Performance Synchros on several cars for thousands of miles. We even took the JHM B5-S4 to Las Vegas to Wuste 2012 with the synchros installed. 

 

 

The JHM-Performance 01E 6-speed Full Rebuild Kit w/ Updated 1-2 Collar INCLUDES THE FOLLOWING:- JHM PERFORMANCE CARBON synchronizer rings (6) w updated 1-2 synchronizers included - OEM synchronizer springs (6) - OEM input shaft seal - OEM output shaft seal - OEM front output shaft seals (2) - OEM selector shaft seal - OEM case gasket - Rear Tailshaft Housing O-ring - Front Differential O-Ring - Selector Shaft Cover O-ring - also a new OEM updated 1-2 shift collar (outer collar only, the inner collar never fails, if yours is locked up just press it apart.) This is the part that causes 1st and/or 2nd gear to lock up when it fails.
