Zf 4 Transmission and jake brake

[hasta2]

  Has anyone had a Jake Brake installed with a ZF transmission. I am having one installed on a L-10 cummins and they can't find where to install the pressure relief switch on the transmission

You need to drill and tap one at the front of the pan call ZF they will tell you where to drill and tap it

If it was me I would just install a micro switch on the throttle linkage
