No Longer Realistic Manual?
I recently returned to playing this after about a month to two month break. I have always played this with my G27 (w/ 3-pedals), using the split h-shifter transmission setting, which I prefer because there was the danger of stalling on off ramps and at red lights. Now all of a sudden it's impossible to stall, and when I release the brake in first gear, the truck rolls forward like an automatic vehicle would at idle.

Could this just be my settings (which haven't changed since my last time on), or my truck's transmission (again, hasn't changed), or did they really make a simulator more arcade-y?

EDIT: I'm using Viper's latest 389 workshop mod, if that makes a difference

Could be mod issue, I keep stalling when releasing clutch without pressing throttle

Alright, thanks.
I'll try that next time I'm on it.

Actually, I just checked it to make sure. You're right, "vanilla" 389 with 450hp engine and 6-speed Alison does start to roll on the 1st when clutch is released even without throttle.

Hmm, must just be that truck or transmission. I've had no control problems since jumping to the 1.5 beta. I did lose progress of a whole job today when I removed a police car mod and then when I completed the job, the next job started with me falling through the earth, space, and time. Couldn't figure out the problem because the game is fine with all the mods installed again. Strange.

It's not the game. It's a mod truck with a poorly configured low RPM torque curve for that truck's engine(s).

To be realistic the engine *should* be delivering enough torque at idle to allow you to move off in first low (or even second perhaps depending on the engine and gearbox combination and gross weight, incline etc.) gear without accelerator, but of course it *should* also stall when you apply enough brake force to stop the truck moving.

This takes a bit of tedious effort to work out so I wouldn't fault the modder too much for not bothering even if they might know something isn't right with them. It also requires some effort at compromise, since the engine to gearbox frictional linkage, as configured in the vanilla game, is intentionally a little loose.

Then, there's also so much guessing when it comes to engines & torque output combinations you've not had any practical experience with, so...

Nope, I have no truck mods and never had one, and still experience same thing in 1.5 beta

I did, but your first statement is still incorrect ;)

No, it isn't, because it wasn't directed at you (The OP *very specifically* stated he was using a mod truck - admittedly I didn't quote the post I was specifically responding to) and you still didn't read it - In so far as the information you've given, the situation you describe for yourself could well be perfectly normal for a class 8 truck, as I already said.

So, is this poorly configured low RPM curve, or normal for class 8 truck?

I've actually had the chance to drive a truck for a short while, they actually don't stall. If you're in a low gear and you slowly let out your clutch the truck will go just like an automatic.

Set your game to "Simple Transmission" and you will stall. Set it to "Advanced" and it will act like a transmission would IRL. Now, on a hill idk if it would go like an automatic transmission, but on a flat surface the truck will go forward.

Speaking generally, you *should* be able to feed the clutch and release the brake to hold the vehicle on the incline, without stalling, before applying accelerator. On the flat, it should move off by itself, without accelerator, with very little effort at all - just a normal smooth release of the pedal.

And if you release it too quicly you shake the whole truck xD Too bad it doesn't do that in game lol.... The clutch in a big rig is sooo stiff lol

Don't forget that these trucks have loads of torque:
973 lb-ft @ 800 rpm for a MX-13 (clutch engagement torque and rpm)...

They do feel a bit like an automatic in the lower gears and with an experienced left foot :steammocking:
