If you have Renault's clip software it will show what's wrong ,it is saying that the valve needs replacing ,looks like its the EMV valves ,if pressure is to low for the torque converter it can't lock up so you won't get drive to the wheels ,the first signed are delays between shifts and then a thump when it goes in gear ,you must reset the software after you change the valves or its back to square one .
Renault automatics were sold on a no maintenance plan if if the fluid needed topping up that's all it ever needed ,said renault ,but the truth is this wrecks the gearbox because the fluid gets contaminated by all of the debris from the clutch packs with theatre steel spacers ,and the bands ,this just keeps being pumped around the system causing damage to valves/valvebody/seals/torque converter/bearings /bushes ect .
Every other auto trans mfg on the planet say change the fluid at 30,000 miles ,renault /Peugeot/citrons are the only ones that don't because they are all part of the French collective ,
These units are designed for dealer service only ,most people don't even know how to check the fluid level correctly because any aspect is shroued in lack of information ,
I have the French PDF on this transmission it shows every aspect right down to customer reports it was ment for training service mechs !
Hope it helps!
