Change gear ratios?

so I've recently made a mod that gives extreme horse power to almost every default vehicle. Only thing is, I don't know how to find the coding for the gear ratios. It's causing the vehicles to put down the power incorrectly and making it behave in an unwanted way.

If somebody could show me where the coding for the gear ratios are then that'd be a great help and I could update my mod

 

Say i was working on the hatch, it would be far down in the hatch_engine.jbeam files, it would be like,
hatch_transmission_4M": {
"information":{
"authors":"BeamNG",
"name":"4-Speed Manual Transmission",
"value":150,
},

"slotType" : "hatch_transmission",

"slots": [
["type", "default", "description"]
["hatch_differential_F","hatch_differential_F", "Front Differential"],
],
"engine":{
"transmissionType":"manual",
// -1, 0 (neutral), 1, etc
"gears":[-3.15, 0, 3.25, 1.65, 1.03, 0.82]
"clutchDuration":0.15
"shiftDownRPM":2800,
"shiftUpRPM":6100,
"clutchTorque":170

 

You might want to boost the clutch torque too, if it's not enough it'll constantly slip.
Also gearing can be adjusted in-game through the tuning section in the car customisation menu.

 

I didn't find that in my tuning section, well not for older cars, the older ones you have to modify the engine.jbeam file
changed hirochi sunburst's gear ratios in game.

 

Rear/front differential gear ratios are usually found in the suspension_R or suspension_F.jbeam.

 

alright I've found the gears in one of the vehicles so far! that's progress and thanks guys for responding
