There were two main transmissions used in the Nissan Skyline GT-R's from 1989-2002. The R32 and R33 used a 5 speed transmission from Nissan(FS5R30A), and the R34 GT-R used a 6 speed transmission from Getrag(V160). The FS5R30A is very similar to the 300ZX transmission internally. The Getrag is the same transmission as used in the Toyota Supra. The input shaft and main shaft are unique to the GT-R, the rest of the internal parts are interchangeable. R32/R33 has 4.111 gear ratio, the R34 has a 3.545 gear ratio. We have seen people running 4.3, 4.111, 3.7, and 3.54 on R32/R33/R34.
The Getrag is loud at idle. The synchros aren't that durable. Even though the Supra guys run them pretty hard, we break weird hard parts in them. They are a newer transmission and offer 6 speeds. The price on them is going up, but they are still a popular swap. Nissan Skyline GT-R Transmission and Upgrade information

Transfercase - The Getrag uses a specific transfercase, so you can't just reuse the one off your R32/R33.
|R34 race car transfercase with cooling. Notice no wire to speed sensor|
|Dirty Getraf with transfercase. They can often puke fluid out of the transfercase.|
Shifter assembly. Obviously the 6 speed shifter and knob is different than the 5 speed.
|Wires, wires everywhere.|
Driveshaft - The R32/R33/R34 use a two piece driveshaft. You can get by, with just changing one section of the shaft.
|Top is a Nissan Skyline factory driveshaft. The bottom is a carbon fiber for a GMC Syclone/Typhoon|
Front propshaft - The length is different between the R32/R33 and R34. R32/R33 flange to flange, not overall length is 27 inches. The R34/Getrag flange to flange is 28 inches.
|This Getrag has been converted to push style clutch actuation.|
|R34/Getrag front propshaft 28 inches flange to flange. One inch longer than an R32/R33 propshaft|

Clutch - The OEM clutch is a pull style clutch. Most aftermarket clutches are push style. Most. The exceptions being Exedy/NISMO. Push vs Pull Clutch information

Crossmember. You can swap the crossmember if you want, or just modify your OEM one. Two bolt holes, slightly different spot.
|Now if I remembered which was which....|
Transmission mount- See above
Wiring harness changes - The plugs are different. The circuit is pretty basic. We will find the proper diagram and put it here eventually.
Various bolts - Some are different.
Specific Fluid - We have run Redline High Temp ATF with success. We have also used the Toyota Fluid
Everything is pretty straightforward. Remove the old transmission, install the Getrag. If you have all the right parts it should go smoothly. We have seen NISMO mention that the floor needs some hammering, but we didn't run into that issue in the R32 GT-R's that we have done. The recommended gear ratio is 3.7. Splitting the difference between the R32/R33 4.111 and the R34 3.545. If you have ever seen the Mines R34 getting down on video, we think that car is running the Getrag with 4.3 gears. Using some mechanical advantage.
