2004 TRANSMISSION
Automatic Transaxle Overhaul - Endeavor
GENERAL INFORMATION This automatic transaxle is made up of the following main parts.
The gear train is made up of 3 multi-plate clutches, 2 multi-plate brakes and 2
planetary gears made up of a sun gear, carrier, pinion gear and annulus gear.
The torque converter employs a 3 element, 1 step, 2 phase lock-up clutch.
The cases consist of a converter housing, transaxle case, rear cover and a valve
body cover.
Parts related to oil pressure regulation are the oil pump, which pressurizes the oil;
the regulator, which controls the pressure setting; the solenoid valves, which
changes the oil pressure with electrical signals; the pressure control valve, which
controls the oil pressure coming from the solenoid valve that effects each clutch and
brake; each kind of valve, which carry out the retention of the oil pressure through
the lines; and finally the valve body, which houses all the valves. SECTIONAL VIEW < F4A5A >

DIAGNOSI
S
STEP 1. Remove the radiator cap and check for coolant contamination.
Q: Is the coolant contaminated with rust and oil?
YES: Replace it. Refer to ENGINE COOLANT REPLACEMENT
.
NO: There is no action to be taken. Go to Step 2.
STEP 2. Check the radiator cap valve opening pressure.
1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the gauge indicator stops moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93 - 123 kPa (14 - 18 psi)
NOTE: Be sure that the cap is clean before testing. Rust or
other foreign material on the cap seal will cause an
improper reading.
