Mm interesting file, 6 speed but with space for 8? For some reason the ratios appear to be duplicated:
294D3E & 294D40- PT_rTraGear1_C
.....
294D52 & 294D54- PT_rTraGear6_C etc...

Thank you very much.
The meaning of all this does not work cruise control in sixth gear after replacing the transmission.
What area indicates the gear ratio of the main pair?
What is the formula for calculating the gear ratio?
Watch in 16 bit or 32 bit mode?

[DiegoStud]

16 bit factor of 0.01. They're not the most precisely done things, if they were neither would cruise control work for you in 4th and 5th.
Just lengthen 6th for 0.6 to 0.55 or until it works.
You also may need to adjust the 6 gear V/N min and max ratio windows that are just afterwards (16 bit factor 0.00001), can't figure out which one.

Today writed an ecu with a fixed dump. The result is the same. The sixth gear cruise still doesn't work.
Ideas are already over.

Now there's some useful information.
If I see it correctly 294D94 is Tra_rVn6H_C or the upper limit for the V/N ratio in 6th. Currently it is 0.05. Looking at the previous gearbox V/N ratio for example 6th- 115.7kmh/2500rpm= 0.04628 therefore it falls within the acceptable window for gear plausibility. However on the new gearbox 143/2500= 0.0572 which is outside the window and may therefore be the reason for the issue.
So I would recommend increasing to 0.06 and trying that.

Thank you very much for your help!
Editing the upper limit value at 0.06 helped. Cruise control began working in sixth gear.

I have same problem. I change gearbox in fiat ducato and cruise not work on 6 gear :/ is such a change enough?
