Genuine Cotta Replacement Parts

You Should Only Use Genuine Cotta Replacement Parts

Only Genuine Cotta Parts are designed to match our exact standards, tolerances and OEM specifications so that they will fit perfectly and work optimally in your Cotta brand of equipment. We maintain an extensive inventory of standard service parts, and any non-stock parts are made to order in our factory here at Cotta. We offer an expedited processing service as well, which reduces your lead time by “hand carrying” your order through the necessary steps.

How easy is it to find the part you need?

All we need is the Stock List Number (P/N) or serial number on your transmission’s nameplate, so we can match it to a correct Bill of Materials. The serial number is either a base 5-digit or 6-digit number (shown here). If the nameplate happens to be missing, you can provide us with the serial number stamped into the gear case. It is usually visible when looking down on the transmission in its installed position (also shown here).
