This will be a basic DIY on performing a Manual transmission fluid change on 2014+ models. I take zero responsibility if you screw it up, cut corners, use incorrect fluid etc so follow at own risk.
Jack with jack stands OR Car Ramps
10mm socket & ratchet, Optional(Small Power Impact gun to speed up the process)
Phillips screw driver or Phillips bit with Impact gun
Flat head screw driver, Optional(Plastic fastener removal tool to help remove plastic tabs from undercarriage)
23MM Socket Standard length (Deep socket will have issues removing Fill plug due to cross member clearance)
Optional but much easier: 18" Breaker Bar used with 23MM socket
2 Gaskets for Fill & Drain Plugs Same Part No. 9956-41-800
3 Quarts of Gear Box Fluid (I used Redline SAE 75w80 GL-4)
Manual Pump with hose 24" minimum or 24" hose with Funnel
Optional Cold beer
Step 1: Make sure car E-Brake is engaged if using Jack.
Step 2: Jack up car (Everyone has their own particular spot they use), apply jack stands in desired location/Drive car onto car Ramps(2nd set of eyes to guide car up ramps would be recommended, engage E-brake).
Step 3:Using Flat head screwdriver & Plastic fastener removal tool remove all plastic tabs from undercarriage.
Step 4: Using 10mm Socket & ratchet/Power Impact gun & slowly remove all 10mm screws
Step 5: Remove undercarriage & place to the side.
Step 6: Place Drain Pan underneath the Drain Plug
Step 7: Using 23mm socket with breaker bar break loosen the Fill Plug first, ALWAYS verify it can be removed prior to draining transmission.
Step 8: Now using same socket & breaker bar break loose the drain plug & remove, drain transmission.
Step 9: While transmission is draining remove the old gasket off of drain plug & replace with new gasket. (NEVER REUSE GASKET BEING THEY ARE A ONE TIME USE GASKET, REUSING WILL CAUSE SLOW LEAK & WILL REQUIRE TO REDO THIS JOB.)
Step 10: Remove Fill plug & replace Gasket as well.
Step 11: Reinstall Drain plug with new Gasket, Torque down 30-43 ft/lbs
Step 12: Open Hood
Step 13: If using Hose with funnel run hose from top of motor down to the Fill location & insert hose 2-3 inches inside so that hose won't slide out during filling process, If using pump you can pump fluid underneath car.
Step 14: Now slide the same drain pan underneath the fill location to catch the runoff of transmissions fluid when adding.
Step 15: Add fluid to transmission (you will use 2 at minimum, I had to use 1/4 of 3rd bottle being front end of car was jacked up)
Step 16: Continue adding fluid until you see the fluid running out of the fill plug.(You are now Topped off)
Step 17: Remove hose from fill location
Step 18: Reinstall Fill Plug & Torque down 30-43 ft/lbs.
Step 19: Remove Drain Pan
Step 20: Reinstall undercarriage
Step 21: Use car Jack & Jack car up to remove Jack stands then lower car back to ground/If on car ramps remove blocks from rear tires, disengage E-Brake & drive car off ramps.
