"Gear Commander" is a tool* I developed and use to better control the games old automatic transmissions, mainly for dyno testing and debug purposes**, which I subject all my relevant mods to in order to optimize the parts and insure quality. The Gear Commander's main function allows you to override the transmission gear layout from PRND21 on older cars to PRNDM or PRNDSM or PRNM using the "additional modifications" slot in any supported vehicle (see list below). This lets you have full selection of the gears in any of the slush-boxes, and lets you keep the slush-box in a higher gear without dealing with kick-down, which was the issue I ran into when dyno testing older vehicles. I quickly realized its potential in applications beyond my testing purposes, such as drag racing and towing and began to add more features and support for more vehicles.
*Keep in mind that this is an experimental mod for a reason. It is a tool, not a refined product. Some of the variables and options may not work and/or may not be needed on certain transmissions and certain vehicles. Its really not meant to be 100% perfect, its mostly meant to function and do the job it needs to do, which is to control the transmission and it does exactly that.
Included Features of "Gear Commander":
- Ability to overwrite base gear layout and have a full manual mode on the automatic transmissions in supported vehicles (see supported list below)
- Ability to adjust transmission shift speed from the typical vanilla transmissions value of 0.25 seconds down to 0.05 seconds, allowing the slush-boxes to shift like the modern automatics in the game
- Ability to add a transbrake, a feature of the drag transmissions that you can now drop into an automatic in any of the supported vehicles
- Added slip torque variable
- Allows users to add over to 25,000lbft (35,000nm to be exact) to the torque convertors slip limit, meaning you can make virtually whatever power you want and tow whatever you want without the convertor slippig
- Added "Extra Options"
- Indestructible Long Block: Borrowed from R4NKING.
- Engine Cooling Override: Also Borrowed from R4NKING.
- both options let you push your engine as much as your transmission. Not really something I use when dyno testing for obvious reasons but useful for excessive towing and drag racing applications/builds

*Bastion is a WIP thats included because I couldn't be bothered to remove it. Theres nothing inherently wrong with it, its just that the modern transmissions obviously are setup with some differences from the old school ones I developed this mod for, so its not quite as optimized. The option to change the gear pattern is deactivated fully in the bastion, as its automatics have a manual mode already making that function redundant, but you can still do everything else. Ill probably do the modern ETK's in a similar vain.
Future plans
- Support for more vehicles
- expand and experiment with different controls
**The dynos I use are available via DSCs (DrowsySamCreations) patreon, and if you put the amount of time and effort into the quality of your mods that I do, they're an invaluable tool and are $5 very well spent.You can find his patreon here:
