How often did u use ur Jake Brake ?

Then automated boxes are abusing themselves.

 

ok ... what the heck is jake shifting? ... how can you shift with the engine brake? isn't that the job of the clutch and the transmission? you guys are confusing the heck outta me

 

Sorry, jake shifting is when you shift without the clutch and lift your throttle foot enough that the jake comes on between shifts. You may have heard it...rev..brrp...rev...brrp...rev...brrp.

 

This is BS! Its the idiot behind the wheel that is causing the loss in fuel mileage not the Jake Brake....

I cringed when I read this...... But I know your joking...

Don't confuse them with reality, it will screw up their fantasy's....

Some of the answers here were funny. Some people will believe anything.

I use mine all the time, but I haul more than half a load unlike most of you........

 

It's simple basic physics. Who's to say the engine wont last over 1m miles using the jake everyday, but it would last slightly longer if you never used it. That's extra wear on the rings, bearings transmission , driveshaft, and rears. How much longer? Who knows...

The Jake won't do any damage to the driveline if used properly...

 

I have and will use a "Jake Shift" or two if starting out on a steeper incline where as mentioned forward momentum drops off faster than engine rpm drop. It is rare though cause my Daily driver is an 18 speed so if I'm split shifting it's only about a 250 rpm drop.

I did not think I'd like or need that many gear possibilities "until I drove one" .. It sure makes it alot easier to upshift going uphill at lower speeds when you otherwise would have enough horsepower to pull a taller gear and get moving up the hill.

 

What the hell is this crap supposed to mean?

 

It shows the fact that at higher speeds and higher rpms the brake is less effective than at lower speeds and lower rpms. Not quite sure what it has to do with what the op asked.

 

I think you meant more effective at higher rpms.

The chart shows a fluid retarder too. People in the us mostly remember cats brake saver.
