In order to improve acceleration performance, the stall speed has been raised from 2100 rpm to 2450 200 rpm, by modifying the blades of impeller, turbine and stator. The identification letter A formerly J can be found on a driving tab of the converter. All models have an outside mirror...
Lockout Spring Porsche 924 Turbo
The shift pattern of the 924 Turbo differs from that of the 924. The 924 Turbo has the first gear and reverse gear on one shift gate so that the shift pattern is the same as the 928. TRANSMISSION - Arrangement of Gears, Power Flow Spring 9 continuously holds the selector shaft 13 in the center shift gate 3rd and 4th gear . For example, to engage 1st gear, spring 9 will have to be compressed in order to get into 1st 2nd gear gate. This spring force is also important when shifting from 1st to 2nd...

Reverse Gear LockOut
Since 5th gear and reverse gear are in the same shift gate, there must be a lock-out to prevent unintentional engagement of reverse gear when downshifting from 5th gear to 4th gear while moving forward. Washer 3 performs this function. The torque is transmitted from the drive pinion to the ring gear 2 . Since the ring gear is bolted to the differential carrier 4 , the differential will turn at ring gear speed. Two different size taper roller bearings are used for the differential. The large...
Rear Axle
As of 1980 model year only two different transmission versions will be available for the 924 1. A completely new five speed manual transmission, having code 016 9 code letter VR . 2. The proven three speed automatic transmission RL optional equipment . The five speed manual transmission 016Z, used in 1979 models is no longer built. A modified version of the 1979 five speed manual transmission is still used in the 924 Turbo. The new 016 9 five speed manual transmission has a three-piece case...
