While running my T-maxx I noticed that if you put your finger on the largest black gear to stop it from spinning than the car wont jump or click. It didnt make any funny noises or seem harmful but I was just wondering if this would damage anything. Thanks in advance and any thoughts/opinions would be helpful.

Does this largest black gear have a name? Please look at your user guide and be more specific. If you can't find the name please let us know the location on your truck.
I will advise you not to stick your fingers onto moving parts. This could be dangerous.

The one that connects to the little gear (from the engine) and then into the transmission i did it and didnt get hurt.

and the gear I am talking about is the biggest black gear that is visable right next to the roll cage and the air filter

It's called the spur gear. It will float at idle because it lies in between the engine clutch and the transmission clutch.
When you throttle the vehicle, the engine clutch engages first, turning that spur gear, which is mounted on the transmission input shaft.
As the RPM's of the transmission input shaft ramp up, the transmission clutch will engage (forward or reverse). It's the engaging of the transmission clutch that makes all that clicking.
You should listen to "three-fingers" Eddy.

That large black gear is affectionately known as the "spur" gear. I don't advise putting your finger on it for long periods of time. And let me explain why. First, the reason a T-Maxx jumps and clicks like that is because of the transmission. There is another clutch inside the transmission case. And if you get the spur gear spinning fast enough, this clutch starts to engage. In a lot of cases, people set their idle high enough where this clutch is trying to engage, but not enough to get it to engage fully. Hence the clicking. So, by holding the spur gear you hold the transmission motionless and again, no clicking. BUT, by holding the spur gear, you are also holding the clutch bell with the pinion (the small gear on the engine) in place. More than likely, your idle is high enough where the clutch shoes inside the engine clutch want to engage. By holding them, you are forcing the clutch shoes to rub on the inside of the clutch bell which will heat them and possibly melt them.
The moral of the story? Reduce your idle speed. This will keep the transmission clutch from trying to engage, and your truck won't click or jump.

The clicking is normal during the brake-in period. It will get less and less as time goes on.
The gear is called a spur gear. It is rotating at idle due to friction from the clutch bell turning, due to the fact that the engine is spinning. When the engine rpm increases a clutch inside the bell engages and spins the bell, the bell in turn spins the spur. If you are to touch the spur while the clutch is engaged it will take your finger down to the bone. Even at idle you can get a power serge that engages the clutch and its all over.
NOT A GOOD IDEA, AS A MATTER OF FACT ITS A VERY STUPID THING TO DO!

If you put in a forward only conversion, it stops the jumping and clicking. It makes for a much smoother driveline. No banging of gears.
