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 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. Fig. 1: locating line pressure solenoid ground terminal 3. Remove the bolt and small bracket holding the ground terminal. Fig. 2: removing bolt and small bracket holding ground terminal important: make sure the metal washer that sits on the rubber grommet doesn’t fall off. Fig. 3: identifying rubber grommet and metal washer 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. Skip to step 11 . Fig. 4: pulling ground terminal 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 fig. 5 .

If the support crimp is up as shown in fig. 5 , push it down as shown in fig. 5 . Fig. 5: checking wire support crimp 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). Fig. 6: identifying line pressure solenoid ground terminal 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 fig. 3 . 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.
