Custom Transmission Tune All ZF 8HP, NAG1, 850RE, A580 / W5A580

You can’t take advantage of the increased power from that new cam or supercharger you installed without higher RPM shift points. A the track we’re seen close to .5s drop in ET on a cammed 5.7l Hemi jut by raising the shift RPM from stock 5700rpm to 6700rpm.

Firm/quick shifts and less trans slip during shifts also extends the life of your trans.

We support most all transmissions for your Chrylser car or truck.
