Just pick you out an interval that works for you,,,as these tranny’s do like clean fluid.
Next Z will get a cooler up front beside the oil cooler.
Now you see it wasn’t hard at all...(Pie-Job)

Yeah I’m a DIY’er and like the feeling of doing it myself. Only reason I even considered Nissan doing it cause I have a tech friend who was gonna do it for cheap and because I thought they’d use the machine and pump every bit of old fluid out.

Since they didn’t use exchanger machine and it’d be his first time doing it. I figured why not do it myself. Lol glad it worked out simple and easily and trans feels way better. Thanks again for the tips & advice!

I do mine myself as well and am doing it at 20k interval. Bought my car with 17k and did it at 20k and it was definitely dirty. I removed the pan and cleaned the magnets. I also added 2 bungs that I mig welded in. One for temperature probe and one for a better fill port. Basically when you pump fluid in this transmission the idea is to be under the car with it level and when you do the final fluid service, you are pumping it in and then with the trans at 104 degrees you will remove the overfill plug and drain off the excess fluid WITH ENGINE RUNNING. It's like checking a conventional transmission in park with engine running and warm except instead of a dipstick you are using the standpipe in the pan to set the fluid level. I did mine with engine off the first time by mistake and the car shifted funny. After rereading the maintenance procedure from alldatadiy I realized it had to be running and I was about 2 quarts low. Also my trans temp gauge matches what I measure with my Harbor freight laser gun within a few degrees on the pan surface
