Here at 4DHPClub, we LOVE to TORTURE OEM parts to find their weak points! We certainly do not stop the torture tests at one of the most critical driveline components. We have put in extensive hours of research and testing to provide the best possible transmission upgrades for our customers. 


Once we receive your transmission our services will include a complete tear down along with a thorough cleaning and inspection of all parts including the TCM & Valvebody. If you do not have your own core transmission please contact us prior to purchase.


Every transmission we build will include a complete overhaul of all gaskets, seals, bearings, pump vanes, clutches, and steels along with a new jumbo filter, and a complete pressure switch rebuild. Different build levels will include different variations of these parts as well as additional upgraded parts.


All of our transmission builds come with a 30 day workmanship warranty. If the vehicle is being calibrated by 4DHPClub/Justin White Tuned we will also include a 6 month limited warranty as long as all break in guidelines are followed as outlined by 4DHPClub.


Horsepower ratings are just for a general guideline, some cars may be able to safely produce much higher horsepower figures, some may not be able to reach the specified horsepower rating for their build. The reason for this can be based on many different variables such as weight, power adder type, and calibration to name a few, These horsepower ratings are not a guarantee.


If you have had a transmission failure additional parts and cleaning services beyond what is included in the pricing may be required. We may not be able to determine the exact damage until your unit is torn down and inspected. If any additional services are required once disassembled, we will always contact you before starting work. This may negatively affect the timeliness of getting your transmission built and/or your core exchange amount refunded, as the cost of all damaged parts not included in our normal build/rebuild will be subtracted from your core return amount. 


Above warranties cover the cost of parts only. The transmission must be shipped to 4DHPClub for complete tear down and inspection. Calibration files must be submitted for review upon request.
