S80 T6 Shift Solenoids changed - GEARBOX STILL DOESNT WORK?
 

I bought T6 with a problem code a while ago. Car is 1999 model.

Problem code was: 000C.

It was the Solenoid thing.

Okay so i ordered the parts from a Dealer.

The job was horrible. It took 4 days and 2 men were doing it. It was so horrible. The dude who designed this car was an idiot. It took so much work that you can only imagine!

Okay but ALL solenoids are changed now. Only problem is, that car still doesnt work.

Code 000C is away, than god gearbox is now fine. Im getting a new code, and its: P0702 as a generic OBDII code indicates a problem with the "Transmission Control System Electrical"

What does this mean?

OBD Code P0702refers to
The code is triggered by the Engine Control Module (ECM) when there is a code stored in the Transmission Control Module (TCM)
Symptoms

Possible sumptoms of OBD code P0702
- Engine Light ON (or Service Engine Soon Warning Light)
Causes

Possible causes of OBD code P0702
- Open or short transmission control module circuit - Poor transmission control module electrical connection - Faulty transmission control module - Transmission control module not coded




Im totally lost now. What could be wrong with it? Or does it just need a new programming?

As I know tcm is side by side with PCM at right front of engine compartment, so in the tranny is module housing with all the solenoids and temp sensor, it doesn't need programmed. Make sure all the conectors are in right position and the pin in the big connector not damaged.

Okay so when we pulled the wires and twisted them i was able to change gears manually with tip tronic, up and down gears 1-3 when car was parked.

But when started to drive, it didnt let me do that anymore and third gear stayed on.


So im going to do that next!

Okay so tranny control module was broken.

Changed new module and programmed it on a volvo shop.

Now car works, but it started to give that "s2 solenoid" problem code again? Wtf? Anyways gearbox works normally now?

Okay so sometimes car shuts down all the warning lights and doesnt inform on the screen "gearbox service soon." I drove 40 kilometres whitout any warning lights, then they came back again.


It may stick the third gear on, thats the limb mode? When shutting down the car and firing it on again, all gears work.

Car never went to a limb mode when automatic mode is on, only with tip tronic so far?

Lambda warning light also shuts down when other lights do.

I changed all the brake bads but not front rotors, may this cause some problems?
