(G) Gearbox Fiat 128 Sport Coupè 1100S (1973)

Hello!.

I'm from Spain, My 128 it's fitted with a 1300 Regata engine with the 128 4speed gearbox. Now I have a trouble with it. I'm thinking about to put a 5 speed gearbox from a Regata or Uno.

Do you think , that it's easy to do?. Must be to do some extra work or other modifications?

Thank you!

Here in argentina its very common to change the transmition but you must now that to do.

I have had a 5 speed box fitted in my previous 128. I used a strada 75 5 speed box, and was able to use the standard 128 driveshafts with it. It also cleared the inner wing ok, although I have heard rumours in the past that some people have had to modify the inner wing chassis leg to get extra clearance. Any strada sohc box should fit easily, however, I am not a mechanic and did not fit it personally. The only negative thing I do remember was that when using the 128 gear linkage, (which is only designed for 4 speed of course), you have to push the gear stick down before moving across and forward to get 5th , but I soon got used to that! (Similar movement used for selecting reverse on 128) If you are struggling, I will make contact with the guy who did, and will let you know any important do's and don'ts Regards, Chris ps, very nice coupe by the way!!
