Automatic gearbox behavior

This is my first time playing the game in a year or so and I couldn't help but notice a change for the worse (in my opinion) in the function of the realistic automatic transmission. I remember on the older style autos in the game, once the rev limiter or top RPM shift point was met it would shift into the next gear during wheel spin. Now the "realistic auto" in drive sits on the rev limiter until a speed parameter is met.

Is there a setting or file I can adjust to have the gearbox act like a normal dumb auto?

I'm not sure if I'm the only one who finds this annoying (or cares) considering its in the "realistic" mode.

 

Please first consider looking at the devblog page and checking out this page.

 

It's in vehicleController.lua, you can see from my mod how to use custom version (there might be better ways too, but that is what I managed to do) so you don't need to manipulate original game files.

Shifting logic needs probably addition of torque to shift conditions, or condition which shifts up always if rev limiter is active.

Alternatively you can try to set torqueConverterStiffness in vehicles .jbeam file containing transmission, to something really stiff, but then you will loose looseness of transmission.

I'm hoping to find time to test if I can change transmission to be more torque based stupid version, but it might take a long time.

We should try this, I bet us three can come up with something.

@Matchbox201

Torque/engine load based logic.. I bet all the short falls of the current setup will be gone.

 

We could probably try something like this. I don't think it would be an easy feat though. A lot of inputs and logic to make a TCU. A fully tune-able TCU would be pretty cool though imo.

 

Another thing I just noticed is that for example with Hopper, engine inertia is not changed with automatic transmission, while usually flywheel is replaced by flex plate that can weight just 25% of manual transmission flywheel.

However changing that might cause more issues than fix, it might require lot of other changes.

 

That would be the goal, a fully dynamic TCM (that's what Ford calls and i'm used to it lol).

The inputs are there (throttle, engine rpm, engine load, wheel speed, input rpm).

The controller would need to be re written through.. and Lua is something i'm not good in LOL.
