We accept Visa, MasterCard, and Discover. COD shipments are no longer available. J.W. Performance does not accept any form of electronic payment i.e. Bank Wire, PayPal, Bit Coin, etc… Established accounts may contact J.W. Performance for more options.


All transmissions must be securely crated and affixed to a pallet to ensure a safe delivery. Crating charges are included in the price of all NEW transmission orders. Transmissions sent in for repair will be returned in the crate which it was sent. If the crate is un-useable for return shipment (damaged or insufficient packaging) a crating fee will be assessed. This fee is non-refundable.


Due to ever increasing freight charges, J.W. Performance does not assess a core fee. If you desire to return your used transmission core to J.W. Performance we will apply an appropriate credit to your invoice for the core. A core is not required for transmission orders.


J.W. Performance will be glad to repair your existing transmission and/or torque converter, no matter who originally manufactured it. Lead times can vary depending on time of the year and current work load. If time is of the essence, please contact J.W. Performance prior to sending your repair for current lead times.


J.W. Performance does offer same day transmission and torque converter repair services. You must contact J.W. Performance a minimum of 1 week in advance to schedule an appointment. Due to the uncertain nature of some transmission and torque converter repairs, we cannot guarantee a same day service will be completed in 1 day. Same day service repairs must arrive at our facility by 9:00 a.m. EST. Same day services are only available Tuesday through Thursday.


All shipments are sent fully insured. Any damage claims must be made with the shipping company immediately. Do not send damaged material to J.W. Performance unless prior authorization is given.
