V35 'at Check' Problem

[_L8RSXY_]

hey guys, anyone of you's came across with the AT check light flashing in your v35 and it stucks on safe mode.. basiclly the car drives like a nugget atm .

My cousin bought a 04 V35 and it just happened to him last week and ive never came across this problem before so i cant help ...

He brought to a few workshops and they try to delete the codes but it keeps comming back, the codes saids it has to do with the solenoids but they rip the whole sum out and check everything was working perfect ... so duno wats goin on ay

anyone ?

im gonna guess that the codes that you have been clearing might give an indication.

what are the codes exactly?

might be the ECU that controls the gearbox, depending on the year, there might be one inside the transmission, or one outside. try a new one

[_L8RSXY_]

P0720 VEH SPD SEN/CIR

P1762 D/C SOLENOID/CIRC

P1752 I/C SOLENOID/CIRC

P1757 FR/B SOLENOID/CIRC

P1772 LC/B SOLENOID/CIRC

P0745 L/Press SOLENOID/CIRC

these are the codes thats comming up, dey all been checked and all the Soleniods are working fine , wtf !

It could be something related to them.

I have had the same problem. I was getting throttlebody error codes and in the end it was a blow fuse in the cruise control.

Very time consuming to find the problem. Take it to Nissan or Chris The Man Rogers.

Can not help much with this, however P0720 - vehicle speed sensor (in the automatic transmission) may give a simple clue.

Don't suppose it has had a recent diff ratio change? could mean there is a difference between ABS sensor speed and the sensor in the gearbox.

Not sure it would cause the other fault codes and put it in limp mode though.

Hope this helps.

hop under the car, sounds like something has come. or the auto ECU has died/come unplugged. its located in the passenger footwell on the left.

Think it would be worth looking at this thread, could be a vehicle speed sensor?
