IMHO, beat on any transmission and it will end up with problems.
The MTX-75 is a durable unit if treated correctly. It has been used from at least 95 to the present day.
It is common for the 3rd gear syncro to fail, and the diff is known to be weak.
Probably not as applicable to the MTX-75 coupled to a 2.0 litre ZETEC, you think? Mine is going "great guns" at 200+ miles on the odometer.
