I think I may have overheated my tmaxx too many times. I would tun it show it would have just shift into 2nd gear but about 2/3 of a tank it would over heat and be very hard to start. it would start right up when I started it for the first time of the day. also the inside of the moder looks a Little black. what can I do?

Sounds kind of like you trashed the motor, need to rebuild it. Have you been doing after run procedure?

when i first got into nitro i burned up 4tec motor brought it to my lhs and they said they could do that traxxas engine exchange program so i paid like 90 or 100 bux and they gave me a new one right on the spot. this was also like 2 years ago, but im sure it still is the same

Sounds like your engine is running too lean. Tune it to run well, not to make power, I know it's hard to do but if you want more power, you need more motor.

I know that runing it lean make it over heat, but it shood have the powder to go in to 2nd gear! dos anyone also have this happen to them? Also, how do rebuild it?

You can change the shift point of second gear so it shifts sooner.

You rebuild it by getting a new piston and sleeve and possibly a new connecting rod.
