Manual Transmission Issues

99 4-speed pictured. 900 5-speed similar. 900-style front mount shown in foreground.

• SAAB used the same bolt pattern on all 900 engines from 1979-1993 (+94 CV) making it possible to swap any year engine with any year transmission.
• Non-turbo and turbo transmissions from any year can be swapped, although there is a slight difference in final drive ratio.
• The inner drivers on manual and automatic 900 transmissions are different sizes depending on year/model. The drivers can be swapped if necessary.
• The gearshift centering mechanism differs depending on the model year. Early 900's used a spring with blocks around the selector rod on the gear shift lever housing. In later 900's this mechanism was internal to the transmission.
• Some 900's do not have a center console and therefore employ a different style gearshift boot than console-equipped 900's. The center console itself is compatible between automatic and manual 900's.
