Update: Failed My Road Test

Ya maybe this is why so many are breaking the drive trains now

 

The truck is at a stand still do the math what is road speed for 4th gear at 600rpm idle speed.... The clutch will be slipping until your reach this speed so the higher the gear you use to take off the longer your clutch slips... Also the higher the gear you use the more torque is required and the more torque is applied to the drive train this is this can be compounded at the drive shaft and differentials.

 

@scottied67 - got a video of yourself taking off empty in 4th?

Apparently it's a banned trucking maneuver. Violates the holy grail, sacred book, code of conduct or some ########..... Just want to see if you have it on file.

 

The clutch it's self yes but I suspect this is the cause for alot of clutch adjustment... The more it's used the sooner it has to be adjusted and having to hold it barely engaged until you moving 8 to 10mph is probably hard on the adjustment let alone the clutch?

 

I like the military kids the best salted with bad concrete and seasoned some rust.

Oh wait... /teasing.

Tha did not come out the way Intended at all. Anyway

When I hired people to work on my home to build repair or replace something those with a trade, license etc are on top of everyone else in and there are not too many kids that will give up spring break to go replace a heat pump.

 

I ignored some people. Took me a while to do it.

That cleared out some of the issues. But I just realized I just burned 3 hours this AM in the night working over the thread that does contain people who can use a hand.

 

I have a video taking off loaded in high speed reverse. The truck shakes and shudders violently til we get moving then smoothes out.

I cannot condone or in good conscience advocate taking off in higher gears. I don't get it where the typical truck driver with 2 and a half weeks of training is going to know more about which gear to take off in than the engineer with 6 years of college who works on transmissions for aliving creates LO and 1st gears is to be regarded as a silly mad scientiist to be ignored...

 

I think I can shed some light on what's happening. In Washington State, when you take the driving test, you have a certain amount of time to clear the intersection. Our school had us starting in third. If we were making a left hand turn, we were usually crossing two lanes to get to our lane. So, picture crossroad with, on your left in order, straight/right hand turn lane, left turn lane, the lane you are turning into. We had to start in third, shift to fourth, shift to fifth, turn, wait until truck and trailer were straightened out in our lane of travel, cancel turn signal, shift to sixth, etc, etc. If you spent too much time in the intersection, you got points taken off.
Most likely OP's school has had problems with students up-shifting and turning at the same time and want them to start in fourth so they either; only have one up-shift and then just have to turn, or just worry about the turn thinking starting in fourth will get them through it fast enough to not get points off.
Could also be they are skimping on intructors and the students aren't getting enough behind-the-wheel time. I'm starting to appreciate the school I went to more and more.

 

Me to, life! Never sat with a trainer, never had a clutch replaced, have it drawn down every other year. Thats it
