What are the differences between the 336 gearboxes? 336-33

Hi everyone, after some searching online and searching through my workshop manual and Renault 16 engine workshop manual, I cannot find the answer to my question.

My S2 has the original 336-26 4 speed fitted.

I went to a self serve wrecking yard and removed a 336 gearbox (transaxle) from a Renault 16 car. I just want it as a spare because it was cheap + they are getting harder to find in Australia. I thought I could use it for parts if I end up requiring them later down the track when my Europa is on the road.

Since it is from a Renault 16 there are some obvious visual differences. (I was aware of this.) Bellhousing, clutch fork opposite side, end housing different, shift linkage totally different.

What I want to know is: what is a 336-33 gearbox? That is what this one is.

What does the -33 designate? All I can find from my Renault manual is that it means it is from a RH drive vehicle and "poor road type vehicles and special equipment" What does this mean exactly?

See attached picture from the Renault manual I have.

There seems to be a variety of models of 336. 20,21,22,23,24,25,26,30,31,32,33,34,35,36,37.

I am curious to know what these numbers mean.

I wonder if it is strengthened in key areas to take tougher road conditions or longer periods between overhaul?

That's probably more information on the different types than I've ever seen.

Note that the R16 transaxle turns the wrong way for a Europa though other parts could be useful as spares.

Yep, understood.

As Bodzer said as well, I wonder if there is a difference in strength?

Or ratios? Maybe the gear ratios for the "poor road conditions" are taller?

Probably lower for more low speed work.
