What are codes P0733 and P0736 indicating on a 2002 Jeep Liberty?

Codes P0733 and P0736 on a 2002 Jeep Liberty refer to transmission-related issues. Here's what each code indicates: P0733 - Gear 3 Incorrect Ratio: This code indicates that the transmission is not shifting into the third gear correctly. It suggests a problem with the gear ratio between the input and output shafts of the transmission when the third gear is engaged. This could be caused by issues such as a faulty transmission solenoid, a worn or damaged gear, low transmission fluid level, or internal transmission problems. P0736 - Reverse Incorrect Ratio: This code indicates that the transmission is not shifting into the reverse gear correctly. It suggests a problem with the gear ratio between the input and output shafts of the transmission when the reverse gear is engaged. Possible causes could include a faulty transmission solenoid, a damaged or worn reverse gear, low transmission fluid level, or internal transmission issues.

Both error codes you have are transmission related. P0736 is an error for reverse has wrong gear ratio. P0700 is a general transmission problem code

Transmission service urgent code PO733

code refers to gear 3 incorrect ratio. causes ---wiring---TR sensor/switch--shift solenoids-- transmission mechanical fault. It is not possible to have the wrong ratio unless you have done something serious to the tranny. So the cpu is reading that the gear selected is wrong for the settings in the cpu. This means that the shift solenoid is not working properly and/or the TR sensor /switch is faulty. I would go for the sensor as it probably controls the solenoid as well. Use only genuine as cheaper units are not always compatible with the cpu.

P0Z80 trouble code

problem could be transmission range sensor or faulty shift solenoids.i would let transmission check it out using diagnostic equipment to check transmission shift solenoid the scanner will manual test solenoids see if they are working.and scanner will check transmission range sensor make sure transmission shifting in right gear.

97 caravan po733 p0734 p0776

Code 733 is a wrong gear ratio for 3rd gear, and code 734 is a wrong ratio for 4th gear. The computer is getting a reading from the transmission that the output shaft is turning at a speed different from what it should be when the transmission is in each gear.
Code 776 is for a problem with a pressure control solenoid.
Could be a problem in the transaxle or the control module.

Passat gear two ratio incorrect

This means that you have a problem in the shift solenoids of this electronically controlled transmission or a fault in the mechanical part of the transmission, this can be hydraulic fluid pressure loose or a defective valve body. In order to know the exact nature of the fault with 2nd gear some diagnostic testing must be done.

My came with a code po734 is that a big problem?

DTC P0734 - Improper Ratio for Fourth Gear.
P0734 is detected when A/T cannot be shifted to the 4th gear position even if electrical circuit is good.

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (4th) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems
- Transmission hydraulic control circuit

Tech notes: Start by inspecting the transmission fluid level and condition, and change fluid if necessary.

Ford trauras trouble code 732 - was told transmission code 732 was being produced, what does a code 732 say?

P0732 FORD - Incorrect Second Gear Ratio
Transmission in second gear and the ECM detected an incorrect gear ration. This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Incorrect transmission shifting

Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Shift solenoids
- Transmission mechanical problems

How can you tell what trans is in 01 grand cherokee laurado 4.0

Here is an article I found talking about the Transmission. The second generation Grand Cherokee: 1999-2004 Jeep WJ The first Grand Cherokee was redesigned in 1999, for lower production cost and greater performance and reliability; it was Chrysler's first use of an electronic bus to replace individual wires throughout the body.

Jeep five-speed automatic transmission

An all-new, electronically-controlled transmission with five forward ratios including an alternate second gear ratio for improved performance for passing and better fuel economy is available with the V-8 only, and was designed specifically for Jeeps.

The transmission features unique characteristics such as a tall, 3.00:1 first gear that gives the driver better initial acceleration. Real-time driver adaptive shifting fine-tunes the shift pattern to the driver, while an alternate second gear ratio gives the driver five forward ratios. During acceleration, second gear has a ratio of 1.67. Depending on speed and throttle position, both this gear and an alternate 1.50 second gear ratio are available for kick-down operation, making the down-shift smoother. Its reverse gear ratio is equal to the first gear ratio, to allow for heavier loads.

Other features include three planetary gear sets that combine the widest range of gear ratios available in any transmission in its class. Combined with precise step selections, this brings smooth shifts and maximum power and optimal fuel economy.

The transmission is built at the Indiana Transmission Plant in Kokomo, Indiana, in an all-new 1.2-million square-foot (110,000 m2) facility.
