Whichever brand you go with (Jacobs, BD and PacBrake are a few of your options), you're going to have to make some provision to lock up your torque converter when the exhaust brake is active. Otherwise, you're going to get little or no retarding and high transmission temperatures from the fluid shear in the unlocked converter when the exhaust brake is being used.
This is the reason that Dodge did not authorize use of the Mopar/Jacobs brake with the 47RE automatic transmissions of the 2nd generation trucks. (Our 2002 3500 dually had the NV5600 6-speed manual transmission - I used the Mopar/Jacobs exhaust brake on it and can recommend it highly.)
There are various aftermarket sources for the torque converter lockup device you'll need. Check with your e-brake supplier, and they should be able to either supply it or point you to someone who can.
