Testimonials

A GREAT big thank you to the amazing and professional staff at Diff Trans. After supplying and installing my gearbox in my VE Commodore, i can not recommend more highly of this company. The staff were so respectful toward me which is quite uncommon and hard to come by being a female and kept me involved every step of the way. Your dedication and hardwork is very much appreciated!! Will definitely be recommending you to family and friends.
