*$3,835 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. Also, if your vehicle is pre-2010 we may need to install a new upgraded pump stator
(cover) and 1-2-3-4/3-5-R drum, which are about $300 each.

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. Please understand that proper tuning of the TCM and ECM are mandatory. All 6L90’s are torque base shifted units. The torque signal is calculated thru the ECM. Therefore, transmission performance & longevity are directly dependent on the delivered torque signal that’s calculated in the ECM. If this is not done properly, you will experience premature transmission failure. We also do not recommend maxing out pressures or deleting torque management completely because it will cause seal failure and/or hard part breakage. Please contact us for tuner recommendations. A review of final tune and final log files is included. Once your final tune and log reviews meet our requirements we will document this in our records for warranty purposes. Please only drive the vehicle for tuning purposes until this process is completed. 

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.

Auxiliary Cooler You need to install a stacked plate auxiliary transmission cooler (not a tube & fin style cooler) rated for 25,000 GVW. The ideal operating temperature for this transmission is 180°or less. These transmissions have a tendency to run very hot – the cooler will lower operating temperature and recovery time which in turn will extend the life of your transmission

Thank you for the opportunity to assist you.

Stay Safe and Have Fun!
