reports of transmission

[igor]

hi to all I need a list of the ratios of the gearboxes and differentials for various vehicles
would I need to do performance testing of the cars in the street before and after the changes, and also if s? that are not reliable as a test on a bench-I need to get an idea of how it behaves in the car
but to do this ? need to know the gear ratios and the differential ir? other parameters provided by the booklet etc, and then I was wondering if there is a list or a database of these data
thanks in advance

as the tests are as reliable as the dealer can not find a windy day and if gauges everything perfectly, just try with the file ori, leaving the cv exact declared.
I am not aware of a list, but all data on the fiat group are located in the eLearn, or if you are looking for a good on the network we are on a forum, grouped, of course only in the FAL.
