So I got my Tmaxx going all purdy. Is there a guide to setting up the reverse? I had to take the gearbox apart because it kept jamming (was a bit of crud inside, but it's high quality and wasn't damaged). To do so I had to reset all the servo's etc.

That part I underlined killed me!!

Anyway, there really is no guide but there is a PDF on the traxxas web site on how it goes together. You just have to make sure all your linkages are adjusted the right way and the reverse & forward gear is engaging all the way.

What kind of "crud" was on the inside? Was it gear powder?

Honestly man, once you've owned a chinese buggy, a pile of dog poop is high quality.

But I bought the Tmaxx second hand, and I tried cleaning it, some dirt owuldn't come off. I used every chemical you could think of + a tooth brush, was seriously hard. He had left the gearbox rubber flap open and some got in. I got a tooth pick and fixed it up. Pain to reassemble though.

Is the reverse gear something you "have" to have? Look at all the parts that you need for that.

Now, If you installed FOC, forward only conversion gear, look at all these parts lol.

FOC. is the way to go with these, less rotating parts means less chance something is going to break plus it's a stronger set up. OPTI drive's bust all the time allowing you to shift it on accident into reverse while it's still moving forward and vice verse. Sometimes when they go bad, it shifts it by it's self making you a nice internal gear salad.

Yeah it is a reverse one, because it did work, and stil kinda does (however I actually have to kill thee engine, change it, then start it again, which defeats the purpose). That forward only conversion looks brutal, I hate the optidrive with passion. How do I install this? remove the gearbox internal's?

Yes, It's actually quite easy once you have the trans in hand, to get the trans out is easy too as you know. You just simply open it up and follow the instructions that come with the gear in the bag.

It's nice to get rid of all that clutter (gears) along with the servo ETC ETC. The trans runs smoother too. Not to mention, you will be making it a bit lighter.

Awesome man, thanks. In the morning I'll be sure to order one. Removing the gearbox alone made me want to kill myself so I started drinking.

Not a problem man.

Take it easy on the snake juice

Or, don't order the part, and eliminate reverse by using the existing parts and your thinker a bit. I guess it just depends. Some people just have to "buy it and bolt it on".

Show us all how it's done then "all mighty thinker fabricator". Your more than welcome.

For the $10 bucks, why bother.....

hmmm... You don't need to be an almighty thinker fabricator to do it. Perhaps you're not capable of, or don't care to do this without someone showing you, or selling you a bolt in part, and that is sad IMO, but the 10 bucks isn't really the issue, for me anyway. The OP is now going to order his part and sit on his hands till it gets to him, while he could be experiencing the satisfaction that comes from doing things himself. Of course like I said, some people are just not into that, I was simply offering the OP another option. I apologize if you were somehow offended.

Im not offended at all Tell me/us, why is it sad?

Im very capable of doing it myself and If there was a way to do it, Im sure the OP is capable of doing it himself too, that statment was insulting.

It's not to late to educate the OP and the rest of the forum on how to do it, he might not have to "sit on his hands" after all.

Im always open to learn something new and If you have the know how, why have you not shared yet after 2 postes?

In which way were you offering another "way to do it" (option) with no instruction? Just curious?

The Tmaxx is still usable, however I'd still like to know how to do it without ordering a part.

You're insulted, but not offended...Ok well, I apologize if you were somehow insulted. If a person didn't have a screwdriver handy, they would be incapable of doing this. There's nothing insulting in that. The sad part (again...IMO) is that people (like you) are satisfied with going out and buying part X and slapping it on instead of using a little thought (hmmmmm....no, too easy) to work out a simple problem. Well...I guess it's good for the economy.

It never gets old being called out by the resident internet tough guy.
OK I will. Just "FYI"

Uhhhhh..... by....thinking? Unfortunately, I'm afraid you may be doomed to that state of curiosity.

Now begone! I'll waste no more time with you.

Sure, but first, if you want to keep reverse, you may want to do a little more digging into the trans to check if the flyouts on the output shaft gears are fully retracting on their own. If the truck is stopped and the spur gear isn't turning, and the truck still won't shift into or out of reverse, that may be the problem. The flyouts have to move very freely and have just enough spring tension as to retract when the output shaft is not being spun.




the 2nd pick shows the adjustment screw. There's a spring in between that screw and the flyout itself.

You'll also want to check the bearings on those gears while you're at it.
