ok, the P0732 and P0734 is a gear ratio problem, and is almost always caused by slipping discs, which would require rebuild, below is the chart for diagnosing this, but as I said said earlier, its almost always a rebuild to fix these,Tim
1. Monitor the shift solenoid command on a scanner and at the same time, monitor the voltage on the shift solenoid control wires with a voltmeter while driving the vehicle. The shift solenoid wires are:
A) Orange/Black (OG/BK) wire at pin 7 of the transmission connector for Shift Solenoid A (SSA).
B) White/Yellow (WH/YE) wire at pin 5 of the transmission connector Shift Solenoid B (SSB).
2. When the scanner shows the solenoid as ON, the voltage should be close to 0 V. When it shows OFF, the voltage should read close to battery voltage. The shift solenoid pattern is:
First Gear- SSA is ON, SSB is ON.
Second Gear- SSA is OFF, SSB is ON.
Third Gear- SSA is OFF, SSB is OFF.
Fourth Gear- SSA is ON, SSB is OFF.
3. If the shift solenoids are being properly controlled when the scanner shows them turning on and off, suspect an internal mechanical or hydraulic problem in the transmission. Check the fluid level, make sure the filter is not leaking or damaged where it may draw air in, and make sure the cooler is not restricted. If all OK, address the internal transmission problem.
