Most often, if damaged components are detected during this inspection, the full internal transmission harness needs replacing. Look up the other , please use the search box. To codes will then be cleared and the vehicle will be taken for a test drive.
General Description The value of the input shaft speed should be equal to the value of the output shaft speed, when multiplied by the 4th gear ratio, while the transaxle is engaged in the 4th gear. Need help with a P0733 code? If the transmission fluid is low or dirty, this could be the first sign of the problem, and the fluid should be replaced or topped off as necessary. If this does not help then you have internal failure, maybe bad selenoids, bad clutch torque converter, bad valve body parts, and even broken gears deep inside.

Low or dirty transmission problem is probably the most common cause of this error code. You need to remove the transmission to repair it. Monitor how the 2nd gear solenoid configuration responds to an increased amount of throttle.
Gear ratios allow vehicles to achieve high speeds and climb steep mountains. For whichever route gets taken, the labor will be expensive, so it is best to make sure the transmission actually needs to be replaced before adding even more money to the bill. Nov 23, 2010 P0732 and P0734 indicates gear ratio errors in 2nd and 4th gears, basically no 2nd and 4th gear. Be sure to rule out all other less expensive possibilities before replacing the transmission. Common mistakes when diagnosing the P0733 code A mistake that could easily be made when diagnosing a P0733 code would be to have the transmission replaced assuming that internal damage has occurred.

Most times, transmission lines will have test ports installed from the factory. The one thing 2nd and 4th gear has in common is the band, the band is known to break, this is a common failure with this transmission and happens on a regular basis. .
Tomorrow I am going to start calling shops. If they are not, you are losing pressure somewhere. The mechanic should compare their findings to manufacturer specifications.

The list of automotive Makes at the right edge of the screen.
The bands and internal clutches of the transmission are usually controlled by the solenoid or through fluid pressure. Depending on the severity of the problem, technicians may perform a torque converter stall speed test to determine whether the stall speed of the engine is within the factory specifications or not. Any electrical issue with a shift solenoid can cause the error code. Have a pressure test done on the transmission to check for internal mechanical failures pump. What are the common causes of code P0734? Locate speed sensor s on the transmission and inspect sensors and connectors for signs of damage.
