It's a manual gearbox... then I personally wouldn't worry much about which oil spec to use, as long as the viscosity spec is right and the quality is the best (synthetic) available. But as I have no idea what the letters mean, I can't say for sure...

In general I agree Anders that using the best quality oil is the best policy.... however, these modern synthetic oils have additives to perform certain duties... some are intended for use specifically with transmissions that have molybdenum coated synchro cones and others are for use with gearboxes having brass synchros. Get it wrong and you could have an expensive repair bill because some additives are not compatible with brass synchros.
In the meantime I have being doing further research.
Tranself TRJ is a semi-synthetic for use in J series gearboxes that are in such as the Twingo, Clio, Megane, Kangoo, Laguna (except 2.2 DT or dCi or the V6) and Espace 2.0 and 1.9dti..... so although it gets used in many different Renault vehicles it is not for ALL Renault gearboxes as the parts guy suggested.
Tranself TRP is a fully synthetic for use in P series gearboxes such as the PK6 having brass single or multi cone synchros.
Tranself TRX is again fully synthetic and classed as a "Super High Performance" oil for use in JB, JC, PK (1, 6, 7, 9) and PF series transmissions in cars and any P series fitted in vans
Tranself TRZ is also fully synthetic for transverse gearboxes having molybdenum coated synchros and is specifically excluded from use in longitudinal boxes having helical-tapered drive trains or boxes fitted with brass synchros.
There are also other "flavours" of Tranself available such as TRT for specific gearboxes... in the case of TRT for the JR5 box in the stretched Scenic.
Renault sure don't make things easy.
It would seem that TRX is the best spec for the PK1 fitted to my Espace but it could need TRZ if it has moly coated synchros.... there is a code stamped on to the gearbox that I have to check first.
At least I am getting somewhere but the bad news is that the oil is £15 (over 21 Euro) per litre from Renault and I need 3 litres.
So far I haven't found what I could be sure to be a direct equivalent from the likes of Castrol.
Sorry for partially sidetracking your thread Mr D.... but back to your issue... if you look down to Page 6 of the technical note it shows that Renaultmatic D2 is a Dextron IID standard oil so there are likely to be a good few equivalent ATF's for you to choose from that meet that standard... and will be cheaper than going to Renault if the price of their synthetic manual gearbox oil is anything to go by. Also if you Google "AR4 gearbox" it seems that it does have some coverage within other Renault forums in the UK that may also be of help.
Most main dealers don't touch auto boxes... they take them out of the vehicle, take them to an automatic transmission specialist and then refit the box when it's been repaired..... so cut out the middle man
