It is possible to swap a Jetta 2006 2.5 engine manual transmission on a Jetta 2006 1.9 TDI engine?
Yes but the gearing is different due to the different rpm ranges.
Thanks , but it is working?
It may bolt up however it will not work because the 2.5 has a way different RPM range. At freeway speeds the 2.5 tranny will cause your TDI to rev very fast.
