I learned how to drive and for the first 4 years I had a truck with no Jake. I learned a lot about coming down grades. Also had my only experience smoking my brakes. When I finally got a truck with Jake's I was glad I had the experience running without them.
Down hill jake braking, what speed and gear do you use?

Y'all offering gear choices without specifying what engine you're running are going to get someone killed! What any ISX and newer Cummins can do is going to leave you in a cloud of smoke with another brand of engine.
77k, 6% and a Detroit? Most likely 35 - 40 mph with the rpm around 2000. You might get away with low 40's on speed if your Jake is a strong one. Depending on your gearing that's probably going to be 5H or 6L.Another Canadian driver and D.Tibbitt Thank this. -
Is the chance of missing a gear on a downhill and ending up running away worth the 3 or 4 minutes you will gain going down the hill 1 gear faster? Are you confident enough in your shifting that you can swiftly and smoothly upshift on a downhill flawlessly or recover from a flawed shift?seagreg, Another Canadian driver and AModelCat Thank this. -

Trucks are different one from another. One fells like you're dragging an anchor while the other feels like the jakes don't do anything but make noise.
I personally set the engine brakes on high and let it hold me back. I'll go 50-55 and let the speed creep up about 5mph higher and with a short (3-5 seconds) and light press of the break bring the speed back down. Anymore breaking than that and I'm going to fast and need to slow it down.
I'm currently in a automatic.
Use manual mode to select what gear to be in. You want a lower gear to up the RPM so the engine break will hold you back. Need a little more speed or RPM is to high just shift up. Starting to go to fast again then just shift down. Save your breaks.Another Canadian driver Thanks this.
