GT350 Diff Fluid Change 

Don't ever follow manufacturer recommended maintenance intervals, it will destroy your car. 150K miles for transmission oil change, lol. I'm changing my diff fluid every 30k, break fluid every 2 years, coolant every 2 years, engine oil every 6 months, trans every 30K miles.

Many owners actually track their cars. The extreme high temps will require changing fluids on a regular basis. Those owners that use their cars for groceries and such can follow the owners manual.

I’m doing mine now at 97576 miles… I wouldn’t wait until 150

azurebluemach why nervous?

Harold Ortiz That I'd have a leak in the fittings to the cooling system.

NAH!!!! But on the other hand, there is also a composite radiator support to save weight ; )

Harold Ortiz it's actually a carbon fiber radiator support.

cabudge09 don't believe the hype it's not actual true carbon fiber it's a mixture of plastic and carbon fibor materials that's why on the radiator support it says carbon fiber composite.

Pischke Performance yes it is sir. Thanks for commenting.

That's my Prelude haha thanks, follow me on Instagram if you wanna see more. joseph__marcano

Fill port is on the drivers side of transmission.

ballzasspower no problem. It's a really easy change. You can actually just disconnect the line without pulling the plug like I did but I wanted to see the magnet and clean it off. -Adam

I had like 20 video clips that I combined to make the final video. I may have inadvertently put them in the wrong order when editing. It was a long day. I reattached and tightened down the line before I refilled the diff. As far as actuating the pump it's not necessary to do the oil change. I got 90% of the fluid out without actuating the pump. I am very thorough when it comes to the maintenance of my vehicles and I change the gear oil every few thousand miles. Because I change it so frequently it's not a big deal if I only get 90% of the fluid out. There is a company developing a kit that will allow you to manually activate the pump and get all the fluid out. Thanks for commenting

Steve B thanks for commenting. There is a thermal switch that activates the pump. I read on one of the forums that someone makes a kit to activate the pump in order to get more fluid out. If you track your car as long as you change the fluid frequently you should be fine. -Adam

erik rod because I track the car and I also wanted to get a look at the oil. Preventative maintenance. -Adam

gt350recon yes, it actually started to trickle out when I finished filling it.

Gotcha. Thanks.

I have really been thinking about it. I think eventually I will but I'm afraid I won't like the sound afterwards. The car sounds so good as is...what do you think? Should I remove them?

cabudge09 it does sound really good stock. I kept my exhuast stock and hangs in my garage. I did install the Borla Atak. I always can swap it back to stock.

How do you like the sound. Do you have any video clips of the sound?

Dylan Dunford it wasn't required on the Boss 302 but the GT350 manual calls for it.

Morten Nielsen I'm OCD when it comes to the maintenance on my vehicles. Also, not a bad ideas after you track your car to make sure everything is kosher under the car. I'd have to look in the manual again but there is a recommendation to change the oils based on track hours.

Not if your track your car.

Supplemental document for GT350 indicates 2.05 quarts and 4.25 oz of friction modifier. Nowhere near 6.6.quarts.
