when i was driving my tmaxx yesterday it was running top notch and all of a sudden it dies i started it back up but know just revs up and doesn't go no where if you pick it up off the groung it will go but seems very very weak like a clutch slipping. I'm new to gas rc cars so would very much appreciate the help. note: earlier in the day broka a drive shaft knuckle but was replaced and worked fine. please help!!!!

Sounds like your spur gear and slipper clutch. (big gear that sticks out of tranny) tighten that and you should be good.

You still have reverse right?

I beleive that goes between the forward and reverse primary gears on the main shaft.

Okay, well there is a pin, it holds the gears in place on your main shaft? I think thats where it goes.

tranny issues

would this cause it to not work right?

should 4985 spin freely while holding 4984 still?

Yes, because the gears would be sliding forward and not gripping properly I Think.


I havn't owned a Tmaxx in about a year so I am going all off memory.

I broke a 4995 today in my maxx. It made all sorts of noise, but still 'tried' to move. I'm learning the trans, so bear with me. 4995 has a screw pin on it, that holds it to the shaft. Try it.

Hey that's exactly what happen to me. Might sound weird but try adjusting the Highspeed needle. I would crack open my tranny if all else fails.
