right bougt a gear box for my siecento but when i fitted it the speedo was an elec tronic sort so i took this out then put the bit off the original box in but the cable was to short and going so i streched it but this worked for a bit but the speedo was going to quick help me please thanks tony:bang::bang::bang::bang::bang::bang::bang::bang:

Try again with a new cable. My guess is that the issue is the routing of the cable rather than anything else.

so new cable do the boxes have the same setup then so interchangerable

Should be the same. Can't see any logic in FIAT changing it.

Check the eper.

At worst you'll need to pop the speedo drive from the old box into the new one.
