Hello there!
This is my first transmission mod for BeamNG, this mod is still in a W.I.P. state, the mod may not be perfect, but over time I will keep improving things on this mod.
Back then I made a similar mod to this one, it was an Allison Transmission mod, but for American Truck Simulator.
And so, I wanted to make something similar to that mod, so I made an Allison Transmission pack for BeamNG!
Here is a little backstory on this mod.
So, I was doing a little searching around on the T-Series semi, and I noticed that it only has 2 transmission options to choose from, all you had was a 10-speed manual (5 speed ranged) and a 5-speed automatic transmission, so I wanted to give it some more transmission options to choose from and overtime I started supporting more vehicles.
From which is why this mod exists.

Here are the transmission options you get.
Allison (automatic) Transmissions
Allison 10L1000
Allison 1000 close
Allison 2500 wide
Allison 3000 close
Allison 3200 xFE close
Allison 3500 wide
Allison 3700 close
Allison 4000 close
Allison 4430 wide
Allison 4700 deep
Allison 4870 wide
GM Transmissions:
10L80/90
8L45/90
4L30 with A and B
4L60E
4L80-E
4T40E
5L40-E
6T30/35
6T40/45
6L45/50
It's highly recommended that you use the GM differentials that have been added to this mod.
From 2.64:1 to 3.87:1
Please remember that your engine RPM, differential ratio and the type of transmission (gear ratios) you choose will affect your max speed.
Over time I will be adding more transmission options and more torque converter ratios/options.

Stall Torque Ratios:
a10L1000s gets a range between 3.42:1 to 3.73:1
a1000s and a2000s gets a range between 1.58:1 to 2.05:1
a3000s gets a range between 1.77:1 to 2.71:1
a4000s gets a range between 1.58:1 to 2.42:1
All the GM transmissions use base game torque converters due to insufficient data, however they do use real gear ratios.
For the T-Series and Citybus they have their own separate torque converters with different specs for each transmission series, for the D-series, Roamer and Van, they have their own torque converters as an option, but you have the ability to use different torque converters as well, either it be the base game ones, or modded ones.
a10L1000s gets 910 lb-ft
a1000s and a2000s gets 660 lb-ft
a3000s gets 930 lb-ft
a3200s gets 1,250 lb-ft
a3500s gets 1,050 lb-ft
a3700s gets 730 lb-ft
a4000s gets 1,850 lb-ft
a4430s gets 1,150 lb-ft
a4700s gets 1,850 lb-ft
a4870s gets 2,250 lb-ft
Please note this is not a final version of the mod, some things within the mod will have to be adjusted over time, if you have any issues, feel free to let me know, if you want to help me by tagging along to make this mod be as realistic as possible, then let me know, and I will gladly credit you for helping out.

Compatible mods:
T-Series Drivetrain Expansion by epicfacecanada
There may be other mods out there on the REPO that may be compatible with this mod, however for the T-Series and Citybus, the torque converters are separate and have their own slot type names.
For modders who want to support my custom slot type names.
"citybus_converter_xYYYYx"
"us_semi_converter_xYYYYx"
"van_converter_diesel_YYxYYYY"
"van_converter_gasoline_YYxYYYY"
"pickup_converter_diesel_YYxYYYY"
"pickup_converter_gasoline_YYxYYYY"
To explain things more.
x = the letter (abc)
y = the number (123)
For example, for both the Citybus and T-Series, the converter slot type names are listed as "a????s"
? = the 4 numbers of the transmission type
a = the name of the transmission, from which is Allison
s = refers to the word "series"
I hope you find this information helpful, if so then I am glad it helped.
