putting exhaust brake on stock 2004.5 48re

[Gerry R]

I've searched the transmission threads and couldn't find out what would be involved putting a PacBrake or similar exhaust brake on my stock 48re. My combined gross weight is 17.5k and so interstates are no problem but on secondary roads where you can have 10% and higher grades I could use more stopping power.

Ive been looking into this for my 04. Ive looked into all BD products so im going to use their names. You would need the exhaust brake, a transmission controller (towloc), and I would get the valve body so that your holding pressure would be higher.

Let me know how you come out.

I would go with a PXRB from pac brake. I would also consider mild trans upgrades to hold the retarding power. Anyway you go you will need a controller to lock the torque converter. I personally don't like the way BD regulates pressure, looks too easy to plug and fail which would push too much back-pressure to the head.

JohnWhat kind of transmission upgrades would you make?

That's a question I would ask a good trans builder, but I would assume a torque converter and valve body???
