Service Procedure

1. Drain and remove the transmission oil pan.

^ Refer to the AT section in the appropriate Service Manual (ESM) for oil pan removal instructions.





2. Locate the ground terminal for the line pressure solenoid.





3. Remove the bolt and small bracket holding the ground terminal.





IMPORTANT:
Make sure the metal washer that sits on the rubber grommet doesn't fall off.





4. Make sure the ground terminal will not pull completely off of the wire.

^ Use moderate force to pull/push the wire in and out of the terminal (no more than 5 lbs of pull force).

a. If the terminal pulls completely off the wire with 5 lbs of pull force replace the solenoid valve assembly (see Parts Information).

^ Refer to the AT section of the appropriate Service Manual (ESM) for solenoid valve replacement.

^ Skip to step 11.

b. If the terminal does not pull completely off of the wire go to step 5 and continue with this procedure.

5. Check the wire support crimp shown in Figure 5.





^ If the support crimp is up as shown in Figure 5a push it down as shown in Figure 5b.





6. Completely wash the ground terminal with Electrical Contact Cleaner and blow it dry.

IMPORTANT:
If the ATF is not completely cleaned off of the terminal the solder will not stick correctly.

NOTE:
^ Use a local source for electrical contact cleaner.

^ Nissan Trans Cooler Flush (999MP-AM006P) may also be used to clean the terminal (see Parts Information).

IMPORTANT:
You must solder the terminal. Do Not attempt to tighten the terminal crimp by squeezing it with a crimp tool or pliers.





7. Apply heat and solder to the terminal as shown in Figure 7.

^ Apply solder to end of the crimp on the exposed wire strands.

^ Use high quality thin rosin-core solder such as Radio Shack item # 064-005E** or equivalent.

** 0.032" dia. 2.5 oz 60/40 (Lead/Tin) rosin-core solder.

IMPORTANT:
^ Clean/brush off any loose pieces of solder.

^ Use the OK/NG photos shown as a guide to make sure the solder is applied correctly.

NG:





This is a "cold" solder. The solder did not flow into the crimp and between the wire strands.

NG:





The solder flowed too far from the crimp and onto the terminal.

When the terminal is reinstalled the solder will be under the bolt washer and the washer will not seat flat.

OK:





The solder flowed into the crimp and between each of the wire strands.

The solder is not too far out on the terminal.

8. After you have completed the soldering make sure the wire is tight in the terminal.

a. Use moderate force to pull/push the wire in and out of the terminal (no more than 5 lbs of pull force). The wire should not move.

b. If the wire moves (is loose) replace the solenoid valve assembly (see Parts Information).

9. Make sure the metal washer is in place on the rubber grommet.

10. Reinstall the bolt and small bracket that holds the ground terminal.

^ Tighten to 6.9 - 8.8 N.m (0.7 - 0.9 Kg-m 61-78 in-lb)

11. Reinstall all other parts removed as per the appropriate Service Manual (ESM).

^ Make sure to use new oil pan bolts (listed in the Parts Information).

^ DO NOT re-use the old oil pan bolts.

12. Using CONSULT-II erase all DTCs.

13. Test-drive to confirm the incident is fixed.
