HARD SHIFT TO 2ND GEAR AFTER COLD START
Model(s): 1980-91 Mazda RX-7 (non-turbo)
1990-91 Mazda Miata
Category: J
Bulletin No.: 004/92
Date: 7/7/92
DESCRIPTION
Hard shifting into second gear before the vehicle has had sufficient
time to warm up may be caused by insufficient clearance between 2nd
gear synchronizer ring and the 1-2 clutch hub. Design changes have
been made to the 2nd gear synchronizer ring and clutch hub sleeve to
correct this problem since April 1, l99l .
If you experience hard shifting into 2nd gear after a cold start with
an RX-7 (non-turbo) or Miata produced prior to April 1, 1991, replace
the 2nd gear synchronizer ring and 1-2 clutch sleeve (or 1-2 clutch
hub set) with redesigned ones. Refer to the appropriate service
information for installation procedures.
