okay red function light stays on but steering works and i have servo #'s 2018 and 2055 for my gas/brake and forward/reverse. are those #'s the right ones for my truck maby thats why that light stays on.

OR

some wires are shaved or cut but i can't see it any where I've checked.

OR

optidrive sensor is pooched but i dout it

last time i drove it worked good then throttle didnt work 20 seconds later it worked then it cut out and never came back... oh and since i charged my hump pack thanx guys

It sounds like you need to reprogram the optidrive. You can find out how at the www.traxxas.com knowledgebase.

i called the dealer. He said it went into 'failsafe" mode, where the shifting and brake servo's dont respond. He said carge the hump back, i did and it still wont respond to the two new servos:(

check your connections, are you batteries in your radio dead?
Another thing that can happen is possible the wire is broken off of your reveiver on the truck
 
yup i put new energizer's in the radio,um there is one spot where i can see the copper wire, but its such a small spot i dont think in would affect it. I might be wrong. Also maby i should have a look ti where the wires go into the tranny. Behind the little cover, its a sensor i belive.
 
i had this problem too when i first started and it was driving me mad, it goes into failsafe mode when there isnt enough charge in the batterys and it drops below a certain voltage( unsure what the correct voltage is), which is anoying cos you have your batteries fully loaded ready to bash or race, i had a nick in one of my wires so i got a new part traxxas part 3034 for £3 in the uk, i would definately give this part a go first as my steering would work the same way you are describing, good luck mate and let us know how you get on:D
 
Do a search on here on the optidrive. It's useless weight. As long as you don't shift your rig while it's moving, there isn't a problem. Most people ditch reverse along with it. A forward only conversion is usually the first mod that people make to Maxx's because it's the best cheap, performance upgrade. Quicker, smoother acceleration and a way stouter tranny.
 
haha i fixed it, i took out the optidrive.ya ill make sure the machine is stopped when i shift
