Get three gages exhaust gas temperature, transmission tempature, and turbo charger pressure. Mine are mounted on the drivers door post where I can see them with ease. I recommend check out dieseltrans.com, the DTT site, they have for your truck. My Dodge diesel with an auto tranny has been modified with the DTT valve body, torque converter and smart box. This allows me to set the points where my transmission will lock up in 2nd, 3rd and OD. For example when in 3rd the tranny will stay locked up in 3rd between 28 and 57 mph. This keeps the tranny out of OD until the engine rpm is high on the torque curve, and when slowing down it allows my exhaust brake to be very effective in controlling down hill speed. If you have questions call DTT and they will help.
