I'm planning on replacing my gearbox because it has several problems. Sometimes it makes loud clunk when I put it into gear. Going from 1st to 2nd gear I have to wait for a second before gear actually engages. Selector mechanism is not smooth, seems to snag every now and then. And finally when selecting reverse despite being completely standstill, it slightly grinds.

 

Anyway. Engine is 1.2 TSI CBZA 2014 year and current gearbox is 5 speed MFX with parts number 02T 301 103 AB. Problem is that I can't find locally any that are exact match and I don't know which other ones fit or what difference is there between MFX, LEG etc. I have found LEG 02T 301 103 AB, MFX 02T 300 020 R (RX?). Also pricing seems all over the place. Some low kilometrage go for around ~300€ while another that is much higher goes for ~800€ etc.

 

I would appreciate any help.

After more digging around I found that 1.2 TSI 63kW ( CBZA ) engine came with MFX or LGQ 5 speed 02T gearboxes out of the factory.

Would it be safe to assume that if I go with MFX or LGQ gearbox from 1.2 TSI or 1.2 TFSI ( CBZA or CBZB ) it would fit without problems even if it comes from Fabia II, Polo?

 

Perhaps there is even a better, stronger gearbox option? I have seen few that have same bolt pattern etc but have some other minor differences. For example some 02U 6 speed gearboxes have same bolt pattern, same mounting points.
