2.2
- Rear chassis visibility for interior view
- Added servo to Varashield accessories
- Improved horn sound loop transitions
- Introduction of r_bumper accesory type (existing vehicle configs will need to visit service to fix missing rear crossmember and lights)
- 1.48 support with new structure
- Full DLC support

Thanks Smarty for the update.

Thank you!

@Smarty Can you make the shifts (gears) in sequential mode look good?
So they are: DR1 DR2 DR3 1 DR4 2 DR5 3 4 5 6 7 8 9 10
It should be? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
I also noticed that some gears have to be passed a little faster than others (I don't know if I made myself understand):
1 --->DR2
2 --->DR5
3 ---> 4

I don't know if other transmissions are like this and I don't know if it's normal
By the way, burgers are also embedded in this

@Smarty Did you read the above?

[Smarty]

Oh, I read it. 15 speed transmissions aren't supposed to be shifted sequentially. They have three ranges of five speeds each: deep reduction, low, and high. What's unique about them is that the deep reduction and low ranges overlap by two speeds. This allows the driver more options for when he makes the range shift. The rule of thumb when shifting a 15 from deep reduction to low range is to 'go back one hole'.

So a shift sequence might look like any of the following:
DR1 - DR2 - 1 - 2 - 3 - 4 - (etc)
DR1 - DR2 - DR3 - 2 - 3 - 4 - (etc)
DR1 - DR2 - DR3 - DR4 - 3 - 4 - (etc)
DR1 - DR2 - DR3 - DR4 - DR5 - 4 - (etc)

But more normally, on dry pavement with normal loads, it will look more like:
1 - 2 - 3 - 4 - (etc)
Deep reduction is generally only used for starting and moving in adverse conditions, so off-road, steep grades, heavy loads, and especially any combination of these.

If you're playing with sequential shifting, you'll have similar startability and none of the overlap if you use an 8LL or a 13 speed overdrive with higher gearing.

[oscu0]

wouldn't you want to shift out of deep reduction ASAP to reduce drivetrain friction, like shifting into the big ring on a bicycle?

@Smarty It can't be, I don't understand, I've never driven a real truck or been in one, I'm uninformed
I try to understand, but it is not entirely clear to me how it works
If it's any use I play with keyboard

[PikPikker]

Well, actually a 15-speed transmission is the worst choice for sequential shifting. I'd recommend going with 9, 10 or 13-speed transmissions - literally, anything except 15-speeder, huh..

[Kaog]

@PikPikker Ok I understand, but can you explain to me how this 15 transmission works?
