Hello guys!

I have a problem with my workmate's Kangoo. The original transmission was defected, and we've exchanged it to a new one with longer gears. The original one was a JH3171, and that was replaced with a JR5150.
The problem is, that the cruise control won't work properly, just with the speed limiter function, but when you use that, then you have to push the accelerator pedal. I know that the stored values (speed/engine rpm) aren't the same, what blocks the automatic acceleration.
Does anybody know a solution for this problem, that we could use the cruise control as usual?

Thanks in advance!
