Editing Z31/transmissions (section)

== Manual Transmission Specifications ==

The Z31 came with three different manual 5 speed transmissions. All manual non-turbos used a 5 speed Nissan transmission (FS5W71C) which is quite reliable. The 84-86 manual turbos used a Borg-Warner T-5 5 speed (FS5R90A). The 87-89 manual turbo transmissions are a Nissan made (FS5R30A) model. Internally, they are the same as the Nissan transmission found in z32 turbos, trucks, pathfinders, etc. The 1987 model FS5R30A has a little different gear set than the 1988 and 1989.

All manual transmissions have synchros on all forward gears. If you change the gear oil in your transmission on a semi-regular basis it should give you absolutely no trouble at all.
