*$4,095 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.
We recommend the Billet Reinforced Output Carrier for vehicles producing over 750 RWHP, Nitrous, or Heavy Vehicles (including trucks, SUV's and CTS-V's.) Note: We have seen the stock output carrier (planetary) break in vehicles with less than 750 RWHP. We do not warranty the stock output carrier (planetary) in any of our rebuilds. We highly recommend that you purchase the billet reinforced output carrier. We offer a 6L80 Level 4 Rebuild that includes this part.
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 $200 - $300 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 6L80’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!
