Nissan Maxima Service and Repair Manual: Periodic maintenance

  • CVT fluid
  • Inspection CHECKING CVT FLUID The fluid level should be checked with the fluid warmed up to 50 to 80C (122 to 176F). The fluid level check procedure is as follows:  Check for fluid leakage.  With the engine warmed up, drive the vehicle in an urban area. When ambient temperature is 20C (68F), it takes about 10 minutes for the CVT fluid to warm up to 50 to 80C (122 to 176F).  Park the vehicle on a level surface.  Apply parking brake firmly.  With engine at idle, while depressing brake pedal, move shift selector throughout the entire shift range. 6.

  • CVT fluid cooler system
  • Cleaning Whenever an automatic transaxle is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the radiator must be inspected and cleaned. Metal debris and friction material, if present, can be trapped or be deposited in the CVT fluid cooler. This debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid. In either case, malfunction of the newly serviced CVT may occur. Debris, if present, may deposit as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler through the cooler outlet in order to flush out any built up debris.

  • Stall test
  • Inspection and Judgment INSPECTION  Inspect the amount of engine oil. Replenish the engine oil if necessary.  Drive for about 10 minutes to warm up the vehicle so that the CVT fluid temperature is 50 to 80C (122 to 176F). Inspect the amount of CVT fluid. Replenish if necessary. 3. Securely engage parking brake so that the tires do not turn. 4. Install a tachometer where it can be seen by driver during test. NOTE: It is good practice to mark the point of specified engine rpm on indicator. 5. Start engine, apply foot brake, and move selector lever to "D" position. 6. Gradually press down accelerator pedal while holding down the foot brake. 7.

  • Line pressure test
  • Inspection and Judgment INSPECTION Line Pressure Test Procedure  Inspect the amount of engine oil and replenish if necessary.  Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80C (122 to 176F). Then inspect the amount of CVT fluid and replenish if necessary. NOTE: The CVT fluid temperature rises in the range of 50 to 80C (122 to 176F) during 10 minutes of driving.  After warming up transaxle assembly, remove oil pressure detection plug and install Tool. CAUTION: When using oil pressure gauge, be sure to use O-ring attached to oil pressure detection plug. 4. Securely engage parking brake so that the tires do not turn. 5.

  • Road test
  • Description DESCRIPTION  The purpose of the test is to determine the overall performance of CVT and analyze causes of problems.  The road test consists of the following three parts:  "Check Before Engine Is Started"TM-164.  "Check at Idle"TM-165.  "Cruise Test"TM-166.  Before the road test, familiarize yourself with all test procedures and items to check.  Perform tests for all the check items until a malfunction phenomenon is detected. Perform diagnosis for NG items after the completion of road tests. CONSULT SETTING PROCEDURE  Using CONSULT, perform a cruise test and record the result.
