DYI: AT Fluid Change Steps

Nut_N_Much · 06-26-2012, 10:22 PM

Okay, Sorry it took so long to post, Marines Keep me busy.
This is for AT transmissions 2009-2010 (RE7R01A) these are the basic steps to replacing your tranny fluids. For recommended types of fluids conduct a quick search there are loads of recommendations already on this site.
Steps are strait out of the tech manual for Nissan dealers:

Tools needed:
Nissan Charging Pipe part # (315268E000)
Set of sockets to loosed the drain plug and overflow plug.
AT Fluid needed: 9.2 liter (9-3/4 US qt, 8-1/8 Imp qt)
Fluid Pump: Google (automotive fluid transfer pump)
Home made pump: http://www.aaroncake.net/rx-7/transfluid.htm

1. Step 1:
a. Install the O-ring on to the charging pipe. Fitting treads on to over flow plug hole and you fluid pump line fits snugly over the nipple on the opposite side.

2. Step 2:
a. Use CONSULT-III to check that the ATF temperature is 40C (104F) or less.
b. Lift up the vehicle. Keep level as possible.
c. Remove the drain plug from the oil pan, and drain the fluid.
d. When the fluid starts to drip, temporarily tighten the drain plug to the oil pan. NOTE: Do not replace the drain plug and drain plug gasket until fluid change is complete.
e. Remove overflow plug from oil pan.
f. Install the charging pipe to the overflow plug hole. Tighten the charging pipe by hand it has an O-Ring on it for a seal.
g. Install your fluid pump hose to the charging pipe. Recommend using a hose clamp on the side that connects to the charging pipe so it wont side off and pump fluid all over.
h. 1st Fill approximately 3 liters (3-1/8 US qt, 2-5/8 lmp qt) of the ATF.
i. Remove fluid pump hose to remove the charging pipe, and then temporarily tighten the overflow plug to the oil pan. Watch out for fluid leaks, you don't remove the AT Fluid pan so there shouldn't be any leaks.
j. Lift down the vehicle.
k. Start the engine and wait for approximately 3 minutes.
l. Stop the engine.

3. Step 3:
a. Repeat “Step 2”.

4. Final Step:
Use temp gage to check that the fluid temperature is 40C (104F) or less.
b. Lift up the vehicle.
c. Remove the drain plug from the oil pan, and then drain the fluid.
d. When the ATF starts to drip, tighten the drain plug to the oil pan to the specified torque
e. Remove overflow plug from oil pan.
f. Install the charging pipe to the overflow plug hole hand tight.
g. Install your fluid pump hose to the charging pipe recommend using hose clamp to keep it secured to the charging pipe.
h. Fill approximately 3 liters (3-1/8 US qt, 2-5/8 lmp qt) of the fluid.
i. Remove fluid pump hose and the charging pipe, then temporarily tighten the overflow plug to the oil pan.
CAUTION: Quickly perform the procedure to avoid fluid leakage from
over fill hole.
j. Lift down the vehicle.
k. Start the engine.
l. Make the fluid temperature rise to approximately 40C (104F).
NOTE: The fluid level is greatly affected by the temperature. Always check the fluid temperature on using a temp gage of some kind. Factory recommends “Data Monitor” using CONSULT-III.
m. Park vehicle on level surface and set parking brake.
n. Shift the selector lever through each gear position. Leave selector lever in “P” position.
o. Lift up the vehicle when the ATF temperature reaches 40C (104F), and then remove the overflow plug from the oil pan.
p. When the ATF starts to drop, tighten the overflow plug to the oil pan to the specified torque.
CAUTION: Never reuse overflow plug.

Factory Threats:
• Using ATF other than Genuine NISSAN Matic S ATF will cause deterioration in driveability and A/T durability, and may damage the A/T, which is not covered by the NISSAN new vehicle limited warranty.
• When filling ATF, be careful not to scatter heat generating parts such as exhaust.
• Always maintain the ATF temperature within between 35C (95F) and 45C (113F) while checking with CONSULT-III when the ATF level adjustment is performed.

If Adjustments Are Needed:

1. Install O-Ring on charging pipe have it ready.
2. Start the engine.
3. Make the fluid temperature approximately 40C (104F).
4. Park vehicle on level surface and set parking brake.
5. Shift the selector lever through each gear position. Leave selector
lever in “P” position.
6. Lift up the vehicle.
7. Check the ATF leakage from transmission.
8. Remove overflow plug from oil pan.
9. Install the charging pipe to the overflow plug hole.
CAUTION: Tighten the charging pipe by hand.
10. Install your fluid pump hose to the charging pipe.
11. Fill approximately 0.5 liters (1/2 US qt, 1/2 lmp qt) of the fluid.
12. Check that the ATF leaks when removing the charging pipe and
the fluid pump hose. If the ATF does not leak, refill the ATF.
13. When the ATF starts to drop, tighten the overflow plug to the oil
pan to the specified torque.
CAUTION:
Never reuse overflow plug.

Summery:
Conduct Steps 1 once, conduct step 2 twice then finish with step 4. If ATF Temps are not in the right ranges after step 4 is complete conduct an adjustment.

Trying to attached it the service manual for the AT, has specs, gear ratios, exploded view etc. Its 6 MB will try to re-size

it if I can.

KaienZ34 · 06-27-2012, 08:08 PM

Cool thanks for the info, repped.

harman.khinda · 06-28-2012, 09:02 AM

So as long as we do change it on a really hot day 95F+ we should be good? Its been mentioned using a IR thermometer pointed at the tranny pan to check Tranny Fluid Temps might work but no idea how accurate it would be.m - maybe an in-car TFT gauge.

Nut_N_Much · 07-03-2012, 08:59 PM

Don't know anything about them but does UpRev Software Read Trans Temps? Not sure what they used at the dealer to ck the temp, I agree with the comment about using a questionable thermal temp gage; but if its all you have in the garage its better than nothing. Will look into it more and see what I can fine.

wstar · 07-03-2012, 09:03 PM

Yeah getting the temp has always been the sticking point on doing your own ATF fills with this car. The dealership checks the temp with Consult-III as noted in the quotes from the Service Manual. Consult-III is basically a super-expensive CAN diagnostics thing that only the dealerships have, and only it can read that trans temp number (UpRev, etc, cannot).

The trans temp it reads comes from the TCM (the electronics module in the transmission), and *probably* an IR thermometer on the pan is a decent approximation, but don't quote me on that.

Thanks for the info. I was hoping a tuner could read the temps, I guess you replace the fill plug with thermostat and add a gauge, for people who track there cars.

Is it necessary to get a charge pipe for the overflow hole? Why can't I just stick a vinyl tube deep up into the hole instead of using a charge pipe? Also why can't you reuse the overflow plug? I understand why you shouldn't reuse a crush washer but the overflow plug, I assume, is solid.

Overflow plug is a 5mm hex & I reused mine numerous times,
Also used a 1 gallon plastic pump up chemical sprayer to fill transmission

Posting here to note the importance of draining the overfill hole only when the car is running with the transmission in Park, and not when the car is off.

I took my sweet time to plug up the overfill hole when the car was still off, and found that while the fluid was coming out tons while the car was off, I didn't have enough to drain out when the car was running.

What I ended up doing after running out to buy another jug:

Overfill
With the tube and one way pump still plugged into the pan with the charge pipe, turn on the car
Let the car warm up a bit, row through gears etc, and put it back to park
With car still on, undo the charge pipe
I used to finger to make sure the fluid was properly warm, in addition to the thermometer on the pan.
Once fluid slowed, screw back on the plug.
