Running with JCT, Part Deux

I dunno, I was standing in planning the other day, and was listening to them complaining about Tyson and Walmart setting a shipment where even with a team on it it was tight. And that was with no delays. I believe alot of this is out of JCTs hands.

 

That's just asinine by the shippers...the trucking co's should have a clause that states if the shipper wants the shipment with tight schedules then they will be responsible for any late deliveries beyond the carriers control.

 

Yep, JCT does not set the appointments. The customer does and they don't give two ####s about weather its tight or not.

 

So I think my biggest gripe about the new trucks and the automatics is the shifting logic at low rolling speeds. If I'm comming to a slow rolling stop, about 5mph, and say traffic keeps moving or the light turns green and I hit the accelerator, even gently, it downshifts to 1st about 90% of the time, or 2nd the rest. So at 5mph it automatically shoots me about 1800 rpm then skip shifts to 3rd (or 4th if it went to 2nd).

It also likes to hold 7th while at low stopping speeds until you come to a full stop. You have to be at a dead stop for it to finally drop to whatever starting gear it wants (1-5). So if you come to an almost stop, then take off again (Say the light turned green right when you stopped), you have a lag between throttle and shift while the tranny figures out what the heck to do. Its really annoying at 4 way stops with traffic because with that delay, cars think you're letting them go and jump into the intersection.

The only way I can really get it to "do what I want" with the low speed slowing is to leave the engine brake on on the lowest level. That makes it downshift below 7th. Unless I want to start tap shifting it, which I dont because I WANT to trust it.

I personally think if the wheels are moving at all, 1st is never ever needed, 2nd really either. I was taking off in 2nd or 3rd most of the time in my 10 speed. 1st only if I was on an incline with a heavy load.

And I have to assume the tradeoff of high rpms on shifting to allow the skip shifts offsets the fuel wasted from high rpm operations and going through all 12 gears. In my 14 I almost never let the DD15 go over 1400 RPM on accelerations, unless I was going up a hill, or I was going downhill and had the engine brake on. Unless I want to really granny accelerate it, this tranny begs for a heavy foot to allow it to skip shift at all costs. I shouldent complain really, my MPG is much higher than my 14. LOL

Also, @Aminal once complained about his automatic not wanting to go into E-Coast, shaking, but still getting high MPG from time to time. I think I have figured out what it is because mine will do it too: Its the truck doing a DPF regen while rolling. If you're rolling and you kill cruise and it still wont drop into E-coast and its rumbling, if you hit an exit at that same time, you'll get the "High Exahust Temp" warning, meaning it was regenning. The truck still gets +15MPG, but the truck is having to keep RPMs up to keep exhaust temps up for the regen. In about 15 in it returns back to its E-Coasting 150+ MPG self.

 

Today? I'm always on fire. A cross between Adele and Sponge Bob.....setting fire to the rain and building underwater campfires.

 

It is......the shippers usually set the appts. When they don't, JCT TRIES to use some common sense in setting an appt......but monkeys have a better chance of going to space.

Wait......they did! My bad.

 

You set fire to the underwater rain?

And watched it burn as you flipped your patty?

 

Omfg this is the load from hell. 4 cases damaged and os&d cant get the shipper on the phone on what to do with the damaged product

 

This was on my shower receipt today.

 

Would be great if that app actually worked more tham it didn't. Its got about a 40% success rate for me in contacting the store to turn the pump on.
