Ship your transmission in a plastic tote
Here at RPM we do not suggest that you ship your heavy parts in a plastic tote nearly half of the products that are shipped with this method get damaged in shipping. Due to the weight and size of a transmission and the handling procedures used by FedEx and UPS are not acceptable and result in damaged goods. When you are sending us your parts for repair or returning a product to us for repair please contact us and we can email or fax the paper work for shipping and inform you of the proper way to ship them. We prefer them to be on a wooden pallet banded or strapped tight with ratchet straps.
