The excellent quality of the transmissions produced by ROOTOO comes from highly specialized work, the use of original spare parts, strict adherence to construction specifications, and advanced manufacturer instrumentation used during selection and testing.

With over 40 years of technical expertise, we maintain a stock of approximately 400 transmission parts ready for delivery — both new and regenerated — and offer reconditioning services based on OEM codes or chassis numbers.
