Transmission Fluid Change

This procedure is fairly easy and not any more difficult than an engine oil change. However, it is very messy and care should be taken to keep the mess confined and off of you.

Nissan calls for 75W-85 oil. This requires a mix if using Redline fluid (2 quarts each):

• Redline MTL: 70W-80
• Redline MT-90: 75W-90

Note

This procedure is only for the 6spd manual transmission.

• Fluid (~$30)
  • 2 QTs Redline GL4 MTL
  • 2 QTs Redline GL4 MT-90
• Fluid Suction Gun (~10$)
• Oil drain ($~10)
• 10mm Hex Socket
• Socket wrench
• Gloves
• Jack & stands
• clean up supplies

10mm Hex Socket

1. Jack up car and place on jackstands (make it level and ensure it is stable)
2. Crawl under the car and verify everything looks ok. You will see 1 drain plug on the bottom of the transmission, and 1 fill plug on the passenger side. Both use a 10mm Hex Socket.
3. Slide the oil drain container directly under the drain plug and remove the drain plug. Wear protective clothing and gloves, as this stuff pours out very fast.
4. Remove the fill plug and allow the contents to drain for awhile (10+minutes)
5. While waiting for the fluid to drain, prepare the new fluid for insertion. Get the fluid suction gun ready, and open all the fluid bottles.
6. Check that the fluid is fully drained. Replace the drain plug and torque it down.
7. Move the oil drain container out of the way.
8. Use the suction gun to suck the fluid out of the bottles. The gun i used only held aoubt 1/2 quart. So this job took me 8 passes to fill the transmission completely.
9. Get under the car quick. The suction gun will start leaking fluid if you are not fast. Reach up and stick the suction gun hose into the fill hole. Pump the fluid in. (Repeat until all 4 quarts are used)
10. Once you have finished there may be some overflow dripping out of the fill hole.
11. Insert the fill plug and torque down.
12. Clean up any spills (I used acetone)
13. Get the car off the stands and you are done!

Overall this was a very easy procedure. I highly suggest changing your transmission fluid. It made shifting so much easier. I never believed it when others claimed this, but now I definitely notice an improvement.
