2002 Dodge Caravan, Tranny would shift, DTC P0700, P0725

If the oil smells like gas , pull the dip stick an put a lighter to it ! If it catches fire there is gas in the oil ! you don't won't to drive the car it could explode ! .
P1391 is for camshaft position sensor and crankshaft position sensor. the code is for either sensor or both

With all these codes present , without looking under the hood , I would think you have a wiring harness problem ! I have seen critters make nests in the engine compartment , they like to chew wiring ! Have seen air filter boxes full of dog food . Good luck your going to need it !

P0700 is a informative transmission code, about some problem there; the P0733 and P0734 is the specific problem there.
I would first try changing the fluid and filter. Although the fluid may look like it is brand new, with 100K on the fluid, I can assure you that even if those miles were all highway at steady speed and no load that the fluid has deteriorated and no longer lubricating the internal parts properly and that there is some debris in the ******.If codes return and shifting problems are still present, there is definite internal failure, possibly the pump or in the clutches.
DTC P0733The powertrain control module (PCM) uses the crankshaft position (CKP) sensor, input speed sensor (ISS) and output speed sensor (OSS) to determine engine speed, input shaft speed and output shaft speed. These sensor readings are used to determine the current gear ratio and RPM slip across the torque converter. The PCM uses this information from the sensors to determine if the commanded gear matches the actual gear. During normal driving conditions, the PCM will adapt main line pressure via the pressure control (PC) solenoid to prevent slipping and harsh shifts. Shift solenoid 3 is used to apply or release third gear clutch. The PCM controls 3rd gear by controlling the ground for shift solenoid 3. The PCM will turn the solenoid OFF, open the driver circuit, when 3rd gear is commanded On to apply 3rd clutch. Shift solenoid 3 is supplied ignition voltage from the fuel pump relay whenever the PCM commands the fuel pump relay ON. DTC P0733 sets when 3rd clutch still slips after the PCM has commanded high main line pressure.DTC Parameters
DTC P0733 will set if the PCM detects an incorrect actual 3rd gear ratio when 3rd gear is commanded On when:- The condition exists for longer than 3 seconds (2001)*- The condition exists for longer than 3 seconds, 1 minute is allowed to elapse, then condition exists again for longer than 3 seconds (2000)- The high main line pressure has been commanded- The transaxle is in a forward gear- The input speed is greater than 224 RPM- The vehicle speed is greater than 5 km/h (3 mph)- The speed noise parameter = NO- The steady state ratio fail counter equals 255 for an in-gear failure, or the shift fail counter is greater than 100 on a downshift or upshift to 3rd gear (128=0 or normal operation)DTC P0733 diagnostic runs continuously once the above conditions have been met.
DTC P0733 is a type A DTC for 2000, type B for 2001.**Applicable to vehicles built after June 2000.
Diagnostic AidsImportant: If DTCs P0745, P0746, P0756, P0758, P0761, P0763, P0766, P0768 or P0789 is set, diagnose that DTC first. A diagnosed PC solenoid, shift solenoid 2, 3 or 4 low/high circuit fault DTC may have caused DTC P0733 to set.Important: If a shift solenoid performance DTC P0783, 4th gear stuck ON, is set, diagnose that DTC first. A 4th gear stuck ON may cause no 3rd gear, no 2nd gear, or TCC stuck Off.
Refer to Pressure Ports - Air Check and Parts Description for pressure apply points and for component/location description.
Possible causes of no 3rd gear are listed in the flowchart on the succeeding page.
Verify TRANSMISSION ISS and TRANSMISSION OSS read correctly on Scan tool.
Make sure the pressure control, shift 2, shift 3 and shift 4 solenoids are not intermittently sticking. A sticking shift solenoid 4 may cause 4th gear to be applied from an initial start resulting in no 3rd gear. Audible sound should be similar for all solenoids. A muffled tone indicates the need for replacement.

P0734 refer at ratio 4 gear, and the rocedure is the same.
Hope helps.

how much does a trans control module cost and what is necessary to complete replace

P0455 = Evap leak monitor large leak detected.
This code usually means the gas cap may have been loose or needs the rubber gasket.

P0500 = No vehicle speed sensor signal.
Vehicle speed sensor is located on the transmission near one of the axle shafts (it may need replacing).

P0700 = EATX controller DTC present.
This simply means you have transmission related codes.

P0732 = Gear ratio error in 2nd gear.
This code is of some concern, it means the transmission is slipping in 2nd gear. However the trans may be in limp mode due to the speed sensor code (limp mode means the trans starts out in second gear in order to at least get to a mechanic). The first thing I would do is have these codes cleared as there may be absolutely nothing wrong with the transmission (especially if you pull the trans dip stick and the fluid does not have a burnt smell. The vehicle should drive normally after that. If the check engine light comes back, have the codes scanned ASAP (before any other unrelated code sets). Chances are it may be the output speed sensor if this happens (easy fix). Hope this helps

Regards

From what I've read it seems a faulty crankshaft position sensor circuit can also cause this problem
Need to check for opens or shorts in the circuit.
This is a forum I read on it:
http://dodgeforum.com/forum/dodge-caravan/240435-please-help-p0725-speed-input-circuit-malfunction.html

p1781 is manufacturer control transmission, p0731 is gear 1 ratio incorrect, p1784 is manufacturer control transmission, p0700 is trans, control system malfunction. all of these codes refer to tranny.This code normally points to a faulty transmission control module, but this is an expensive part and you should have an experienced Dodge technician diagnose the problem first. or a transmission specialist. the other codes are probably associated with the p0700 code. have a good day !

If I remember right there are TWO input speed sensors. My '99 Grand caravan did what your did and The dealer recommended replacing both at the same time. I did and it cleared the problem.

Both codes (obviously) point to transmission related problems.

DTC P0700 - Transaxle Control System Fault Conditions
The P0700 code is for information only and the next step is to check for transaxle codes in the Transaxle Control Module (TCM). So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

DTC P2706 - Shift Solenoid "F"
First check your wiring before you get inside and open the tranny up. Could be loose wiring, if not do the operation and make sure you do a heat test with the solenoid before you replace it.

Good luck!

P 0700 = EATX (Electronic Automatic Transmission Communication) Controller DTC Present. = An automatic transmission input DTC has been set in the transmission controller.
P 0740 = Torque Converter Clutch. No RPM Drop at Lockup. = Relationship between engine speed and vehicle speed indicates no torque converter clutch engagement.

Yes the Fluid and Filter Change should take care of this. However, Dodge, Chrysler, and Plymouth Minivans have had alot of Transmission problems over the years. Make sure that whomever changes the Transmission Fluid that they use exactly what is specified. Also, do not let any Mechanic talk you into a Superflush of the Transmission. This procedure does not change the Filter.

Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

Hello! Well - both of these codes are in reference to shift pack issues. P0700 is related to torque management, designed to reduce the RPM's at highway speed and lock up the torque converter. If it's throwing this code, there is a strong likelihood that the clutch packs are damaged. P0740 is directly related and will most likely result in the need for the clutch packs being replaced. I wish I had better news to report. :(

Hope this helps and good luck!
