My MF5 gearbox is acting up. It make a growl in every gear except 4th which leads me to think its the lay shaft bearings that are screwed. I had the oil changed in it about 3 months ago and that quitened it down a little but not alot, so im fairly sure the oil level is ok. Has anyone in brisbane had their gearbox rebuilt and can recomend a good/cheap place to get it rebuilt. Idealy i would like to spend less then $300 on it but if it takes more... PS: Go the Blues!
