As if needing a special tool for filling the 7AT transmission wasn't enough of a hassle, the fluid pumps that they sell to go with it are outrageously expensive. I decided to whip one up from a cheap garden sprayer. I've included a pic of my reciept with all the part numbers you need to grab the stuff at lowes. Screw the adapter into the fill plug. Pour a gallon of ATF in the tank, pump up the pressure, crack the ball valve and let it flow.






This plus an Assenmacher ATF 180 adapter and you're in business

update: CTA Tools 7425 also works and is half the price of the assenmacher

update: The thread pitch for the fill tube is M8x1.0, a threaded hose barb should work and, if available, may only be a few dollars. Good luck finding metric hose barbs locally

All done for less than $70.

*read the whole thread for updates and user suggestions*

 

And to think I wanted to spend $150 bucks on an ATF tool... this is MUCH better! Thanks OP!

Edit: Is there anything special about the fitting other than it can thread onto the pan? I'm assuming it makes it easier to do as a 1 man job rather than a person holding it firmly against the pan.

 

The fitting is an Assenmacher ATF 180 adapter. it threads right into the fill hole. This will definitely be easier to do with one person as you can leave it screwed into the transmission with the ball valve closed while you run the transmission to mix the new and old fluid, then when you drain and are ready for the next fill, just crack open the ball valve. No more quickly puling out the hose and reinstalling the plug while fluid drips all over the place.

 

Underrated DIY.
If you were to buy the tool where you have the pump reservoir and the fitting, you're looking at $225, that is if you manage to buy it because only dealers can buy it off tech mate.

The product number you're looking for J-49829. Good luck buying it, above in OP is the best alternative that is also cost effective and not going to leave you drenched in fluid during the service.

 

Awesome post. I have 10k miles before i attempt.

 

Hit 66k, had a nice day and decided it was time. This worked GREAT. Pumped a gallon of ATF in just a few minutes. Since i had a shutoff valve built in, it made the job super easy.

Used valvoline maxlife and 10oz of Lubegard Platinum. Car shifts like new.

 

Quality post

 

Does it matter what ATF you use? I have a 7t, does the atf have to be oem from the dealership?

 

I used Valvoline Maxlife, which is a full synthetic multi-vehicle ATF that meets nissan matic-s specs. Its about $20 a gallon at walmart or most auto parts stores. The factory stuff is quite expensive in comparison.

 

I have never done this service on this car, so just curious why something like a transfer pump from Harbor Freight would not do the same thing. I mean I get there is a not a threaded fitting, but its only $5 for the pump. Please let me know, thanks.

 

if you want to hold the hose with one hand and pump with the other while stabilizing an open bottle of ATF with your foot, that's your prerogative. This is no spill, no mess and you just have to pump it enough to build up pressure. makes this a quick, no hassle job

 

Yep, if you have a helper the Harbor Freight pump works fine, but if you want a complete DIY that pump that Victory set up is the ticket. Luckily my wife didn't have much going on that morning, lol so she was a willing helper

 

Thanks for the post! I gotta do this before vacation down South.

 

Gotcha. Thanks for clarifying.

 

So I bought all the same products listed and the 1/4 in poly tube does not fit into the 1/4 in hose barb. Do I need a bigger tube?

Also I noticed you use lubeguard, Do you mix that with Maxlife and add it the transmission and leave it in?
