Hi there:
Diagnostic trouble code (DTC) TCM-000C is stored if the control module detects that the vehicle speed and engine speed (RPM) signals do not correspond with the programmed values and that an "incorrect" gear is being used in relation to the calculated gear. This is because solenoid S2 is stuck in open or closed position.

Diagnostic Codes: 000C, 002A, 002B, P0733, P0734, P0756
Tests/Procedures:
1. Clear codes from the Transmission Control Module (TCM).
2. With fluid hot, check transmission fluid for quality and level.
3. Test drive the vehicle. Accelerate from 20-60 MPH when in geartronic mode, gear 4. While doing this, watch input and output speed sensors with a scan tool.
4. If the code returns, the transmission is slipping, and the input and output speed sensors are updating, the problem is internal to the transmission.
5. If transmission is replaced, test ATF for coolant contamination per TNN 43-48. Replace radiator if necessary.

Potential Causes: Transmission Mechanical Problem

Tech Tips:
TCM-002B 4th gear. Incorrect gear ratio. This code sets when the actual gear ratio deviates by more than 10% of what is programmed into the TCM.
TCM-002A 3rd gear. Incorrect gear ratio P0756 - TCM-000C - Shift solenoid S2, hydraulic malfunction If the transmission is replaced, be sure the mating surfaces between the engine and transmission are bare metal and clean. If not, the engine may not start after assembly.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

SOURCE: Volvo s80 water in transmission

It is not unheard of for the transmission cooler to fail in such a manner that you end up with coolant in your transmission, and transmission fluid in your radiator.

If this just happened recently you can usually just replace the radiator and flush the transmission as you said and be fine.

However water/coolant is extremely harmful to the automatic transmission, it can cause the internal clutches to break down inside it and fail.

If it were my vehicle I would take my chances and get a new radiator installed and flush both the cooling system and the transmission, this will more than likely cure your problem.

P 0733 code what does that mean


You could be more specific with the issue:
  • Transmission type (Manual/Automatic)?
  • How did this issue appear?
  • Does the car change gears normally?
Your car seems to be an automatic transmission model?
So the fault code is "Gear 3 Incorrect Ratio"

This means that you may have:
  • Low transmission fluid level or dirty transmission fluid
  • Faulty or dirty shift solenoids
  • Transmission mechanical problems
  • Transmission hydraulic control circuit issue

What does error code P0716 mean on a 2001 Volvo S80?


Trouble Code: P0716
Input Speed Sensor Performance
Possible Causes:


P0716 The TCM detects an unrealistic drop in input shaft speed. ISS DTC P0716 is not failed this ignition. Transmission input speed is 1,050 RPM or greater for 2 seconds. Transmission input speed drops 1,000 RPM for greater than 4 seconds and does not recover with in greater than 0.80 seconds.

Go to a Volvo mechanic for specific help, they will probably replace a faulty sensor.

Best of luck.

Transmission slipping


not necessarily-- Have an oil pressure test done to determine for internal failures.. Have the bands and clutch packs adjusted. Have the oil changed as it may be just dirty oil. Run the fault codes and check for TCM faults. A transmission replacement should be considered the absolutely last resort and a second opinion sought if it is recommended.

I have a 1999 volvo s80 and it transmision stay in third only. when you stop and start to move, it goes very slowlly. what can i do to fix this?


The transmission in this car is electronically controlled by a computer by means of solenoids inside the transmission, there may be a problem there or the wiring or the computer. To minimize cost you must have the system scanned with a special tool to see if any transmission fault codes are present in the memory of the transmission control module.

CODE P1618 - CABLE FAULT BETWEEN AW 50 Q2 TRANSMISSION CONTROL MODULE AND MOTRONIC 4.4 ENGINE CONTROL MODULE. YOU CAN CHECK FOR RECALLS BUT I DONT THINK THERE IS RECALL FOR YOUR PROBLEM. YOUR PROBLEM IN TRANSMISSION CABLE COULD BE LOOSE OUT OF PLACE DAMAGED OR YOU HAVE TCM ECM FAULT.
