How To: 370Z Manual Transmission Removal & Replacement

Brought to you by Sac City Auto Parts—Your Nissan & Infiniti Specialist in California.

1. Preparation & Safety [00:04]

  • Lift the car and place jack stands behind the rear brace arm in the reinforced circular area [00:13].

  • Remove the exhaust system and the center heat shield. If the heat shield bolts are stripped, you can carefully bend the thin metal for clearance [01:23].

2. Interior & Electrical Prep [02:22]

  • Remove the shift knob and bezel to avoid damaging the boot when the transmission drops [02:45].

  • Disconnect the starter and alternator leads at the battery junction. This keeps the car's power on while making the starter safe to handle [03:36].

3. Exterior Component Removal [05:33]

  • Disconnect the O2 sensor brackets, starter signal wire, and the five wiring harness brackets along the transmission [06:28].

  • Remove the shift linkage dust cover and unbolt the linkage (12mm). Use a zip tie to secure the internal metal sleeve so it isn’t lost [08:45].

  • Pro Tip: Pull the shifter assembly out from inside the car to make transmission installation significantly easier [12:09].

4. Draining & Unbolting [13:52]

  • Drain the transmission fluid using a 10mm Allen bit [14:13].

  • Unbolt the starter (14mm) and the slave cylinder/bracket. If your car has an aftermarket external slave kit (like CMAC), be sure to save the spacers [18:13].

  • Support the transmission with a jack and remove the crossmember bracket [20:19].

  • Use a long extension to remove the 17mm bell housing bolts. The top bolts must be reached by "braille" from the rear of the transmission [21:38].

5. Installation & Fluid Fill [35:37]

  • Mate the new transmission to the engine, ensuring it seats on the dowel pins before tightening [38:03].

  • Reconnect the starter, wiring harness, and shifter assembly [46:19].

  • Reinstall the interior trim and shift knob [51:06].

  • Filling: Pump just under 4 quarts of manual transmission fluid into the side fill hole until it starts to drip back out [59:01].
