Auto transmission service kits T30 Hi guys. Have a 2.5l 2006 T30 auto. Done 240,000km and want to do a transmission filter/fluid change. A Repco kit (filter & pan gasket) costs about $50 with 20% off at present. A Nissan kit will cost $177! Has any one used after market filters surely they should do the job. I am sure that the local auto guys don't use genuine. They want about $300 to supply and fit including oil (not a flush). No tricks with replacing the filter is there? Can do the job for about $130 with repco kit and Penrite oil. Thoughts?
