I allways use the jake up shifting down shifting it never goes off. I think the jake helps me becuase it drops my RPMs faster. I can shift with it off just as good but i think i do it better with it on. They tell be you should do it on a road test but how many of you guys do it out there

 

*** you should not do it on a road test****

 

I never do that cause then, it would mess up the shifting cause it comes on everytime you time and is very annoying when you try to go to the next gear and all the sudden it does it. So I would say no way.

 

recently in my '04 leased truck, my jake hasnt been working for about a month now, so that really sucks...i miss it a LOT, everytime they bring it in to get it fixed, they tend to fix "a different problem" and forget about my jake but as far as shifting with it on, yea, sometimes, most not tho.,..that trusk is tricky, the jake is supposed to "cut out" at 17mph, but it tend to work going from 1st to 2nd gear....and with the truck goverend, it holds back to fast to shift properly and the truck jerks alot...so i usually keep it off (when its working)
i sure hope swift has jakes...

 

I never understand people who use the jake while accelerating... sometimes i think they like to listen to the "braap" between shifts.. I don't need to make the rpms drop faster.. does anybody notice the most common trucks shifting against the jake are either dirt dummies or tow trucks... :lol:

 

I guess I thought it was for slowing down only :shock: .

I turn it on if I think I may need it or when slowing.

I never gave a thought to leaving it on. I don't see the point.

 

ROLFLMAO :lol: :lol: :lol: :lol:

 

Ummm.... what's the joke? I'm just a CDL school grad, but that's what they taught--use the jake brake when going downhill to slow, downshift and use the brakes otherwise--which makes me even more annoyed when I hear that BRRAAAAPPPP outside my house. I live on a 2-lane highway on a relatively straight stretch and I still hear the over-use of jake brakes. Almost as annoying as straight pipes on cruisers.

 

dirt dummies what you mean dummies it does take alot of skill to drive a dump truck taking it off road on un level ground in soft mud. Try keeping inside a paver when your going around turns dumping blacktop with out drafting out and spilling 5 ton on the ground. You OTR trucks dont even see off the road your on the blacktop all the time. It is more likely that a dump truck driver could out shift an OTR driver just for the fact Dump truck drivers shifts alot more during the day. With stop and go traffic. dump trucks aint on the turn pike for hours on end in high gear.

 

You are right, but others seem to think that it should be kept on while acelerating. Read some of the post above and oyu wwill see why.
