GTL gearbox code

[Azazello]

I am looking for a gtl gearbox, and I need to know how to distinguish it from a tl (956) one, which is a 354 gearbox too but with shorter ratios...
Is there any code to look for?

The GTL gearbox has the code HAO 146

 

[Azazello]

Thank you very much! This code is stamped on the round metal plate under one of the upper bolts, isn't it?

 

[godlike]

Yes it is.

 

[Azazello]

Should I expect to find the same code even on an equivalent r5 gearbox?

There are also gearboxes 354 (HA0)-150, and -97 (FASA Spanish-built) with the 3,10:1 final drive you are looking for.
R5 gearbox should also fit, but you will need to use your original top cover. You are looking for 354 (HA0) -148, -156, -101, -123, -124, -135, -136, -137, and -144

Thank you Angel, precise as ever.
Tomorrow I will go to a good scrapyard quite far from my home (about 80km), they should have the gearbox I am looking for (so they've told me by phone)... I will bring with me your code list!

 

[Azazello]

Bad news, the gearbox code was not on the list (163); the scrapman assured he detached it from a 1108 engine, but the price was quite high (200€!) and I decided not to risk.
So I am still looking around...

I've found out this one:
http://www.subito.it/accessori-auto/cambio-renault-5-e-carburatore-caltanissetta-33402068.htm

I phoned the seller, he said the gearbox was from an r5 1108 engine (that he has fitted on his r4), but the code sounds quite odd:
534 53 42046, but the second "4" may be an "A"...

 

[angel]

The 163 gearbox was fitted to some "special equipment" 1108s but has a rather low 3,77:1 final ratio.

The second case may well be a 354-53 (4,125:1 final ration, too low again)

 

[Azazello]

Thank you Angel, so turns out I did well refusing both the offers...
Now I will choose the too-expensive-one, trying to lower the price at least till they include delivering...

Or maybe the special equipment one was the right compromise to have a little more couple...

 

[Azazello]

I found another gtl gearbox, sold by a friend, and it is another time a 163 one.
So: what kind of special equipment was it, do you know Angel?
Maybe it is more suitable for our full-of-hills-and-mountains italian landscape?
It could be and interesting matter of discussion...
