AND/OR DTC P0745 STORED
APPLIED VEHICLES:
2003 – 2005 Altima (L31)
2003 – 2005 Sentra
2003 – 2004 Maxima (A33 and A34)

APPLIED DATES:
Vehicles built between:
December 1, 2002 and August 27, 2004
APPLIED TRANSMISSIONS: 4 speed A/T: RE4F04B and RE4F03B
IF YOU CONFIRM:
The transmission fluid is full (correct level) and in good condition (not burnt), and
• There is a harsh shift from 1st to 2nd gear,
and/or
• DTC P0745 (line pressure solenoid circuit) is stored,
ACTIONS:
1. Drain and remove the transmission oil pan.
2. Push/pull the ground terminal and wire for the solenoid valve assembly (see Service
Procedure step 4).
• If it doesn’t come off, solder the terminal.
• If it does come off, replace the solenoid assembly.
3. After soldering, recheck the ground terminal and wire (see Service Procedure step 8).
• If it’s tight, repair is complete.
• If it’s loose, replace the solenoid assembly.
IMPORTANT: The purpose of "ACTIONS" (above) is to give you a quick idea of the work
you will be performing. You MUST closely follow the entire Service Procedure (starting on
page 3) as it contains information that is essential to successfully completing this repair.

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.

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 replacement.
Figure 4
• 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 (999MPAM006P) 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 3.
• Apply solder to end of the crimp on
the exposed wire strands.
Apply Solder Here
• 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 (on the next page) as a guide to make sure the solder is
applied correctly.

NG: No Solder
Between Strands
NG:
This is a “cold” solder. The solder did not
flow into the crimp and between the wire
strands.
Figure 8
NG:
The solder flowed too far from the crimp
and onto the terminal.
NG: Too Much
Solder Flow
When the terminal is reinstalled the solder
will be under the bolt washer and the
washer will not seat flat.

OK:
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).

• 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 DTC’s.
13. Test-drive to confirm the incident is fixed.
