OLDJAGUAR.COM was the pioneer for tuning the ZF 6HP & 8HP transmissions in Jaguar & Land Rover vehicles.
Our team first cracked the JLR ZF TCM in December of 2020, and we put the first 6HP26 tunes to market in April of 2021. Since then we have hundreds of satisfied customers, and some impressive results at the track to show the benefits.
Transmission tunes are usually provided in conjunction with an engine tune, but the benefits are still there to be had without an engine tune, or even with someone elses engine tune…
Transmission tunes can be applied in several ways;
– bring your vehicle to one of our locations to be flashed with our equipment
– list of locations HERE
– purchase your own PCMflash dongle & license, and use your own J2534 interface

– ship us your TCM and we will flash it on the bench
