Wondering where on the vehicle I can get the most accurate level for setting trans fluid at proper fill. Magnetic leveler affixed to underside of trans pan? leveler right on ledge in passenger doorjamb? What is the most accurate? Thanks.

 

You're probably never, ever going to find true level. Just get it to where it looks level with the eyeball and that is good enough. It is how any one else does it.

 

Don't overthink this. Just get it close and have at it.

 

Poured cement floors are pretty level, IMO. The lower level in a ramp garage, for example. Also a pretty good location to measure floor-2-fender height when adjusting coil-overs.

 

Leveled cement floor
Level to the flange of the trans/pan
Place car on 4 stands until the level reads leveled
That would be the best way

 

It doesnt have to be totally level

 

At all, but it helps.

If you've ever taken the trans pan you'll see inside is a metal tube protruding with a flat end, any sort of angle can change everything.
I know that on the floor my car took 2 additional quarts in comparison to the floor.

 

You can use rhino ramps and a jack in the back

 

Thanks for the help. So just to clarify (and the job is done), I was asking where exactly to place the "level" (the actual tool, also called a leveler or torpedo level... the thing with the sight glasses with the yellow fluid and the bubble you line up in between the two lines) on the car to get the most accurate indication and guide of "true level" on the vehicle while have it on ramps in the front and being rased in the back with a jack (jack stands in the rear will not allow 100% true level unless you get lucky). I placed the level on the actual transmission pan (mine is magnetic so I just stuck it right on the pan to give me my readings. I got the bubble dead center right in the middle of the marks (which took some back and forth between the jack and the pan). The drain and fille (4 cycles) went flawlessly and the stream from the overflow hole at the last step of the procedure came out picture perfect with the pan temps at 100F (within FSM spec range) with my IR/laser thermometer. I used 16 quarts of the well-regarded honorable mention synthetic Valvoline MaxLife Dex/Merc. I expect my shifts will improve slightly (better timed, smoother transitions, etc) like has occurred in all of my vehicles when switching over to MaxLife trans. fluid. Not a horrible service to perform, but it does take time (and a well-rigged fluid injector setup -- my iteration was pretty fancy and worked extremly well... if I may toot my horn briefly).

 

Give us some feed back in the future on this valvoline. I spend quite a bit of money on 12 quarts of nissan type f and feel like shifting should be better.

 

Nissan auto trans are picky better to stick with s-matic fluid

 

Mts00p is what I bought which appears to be Matic S and not type f. Still feels like it could shift better

 

Depending on last drain fill you might have to do it again in like 20k miles since you only got like 5qts out and tc alone holds 2qts

 

Maxlife works fine in these transmissions. Had it in for over 20k mi now.
