*$4,775 does not include any Hard Part damage, Torque Converter or TCM/ECM tuning. After an internal inspection of your transmission we will notify you of any hard part damage that will carry an additional cost. Normal range with available upgrades ranges from $5,000 - $6,000.

If your transmission has very low mileage, we may be able to do an upgrade which is less expensive than the rebuild - please call us to discuss.

Warranty varies according to application. Please refer to Warranty Info page on our website.

Shipping If you need assistance shipping your transmission, we can arrange Domestic Shipping (averages $250 - $500 each way) for your transmission. Please complete the Shipping Questionnaire on our website (listed under the Contact Us tab) if you would like us to arrange shipping.

Transmission Tuning We do not supply a TCM or ECM tune.

Flushing Cooler & Lines We cannot stress enough the importance of flushing the transmission cooler(s) and lines, even if they are new. We recommend using a Hot Flush Machine or something comparable.

Thank you for the opportunity to assist you.

Stay Safe and Have Fun!
