Yep. It might still go in that spot. Does it have any threads on it, or is it just a smooth pin?
 
Without looking for my manual yet, it looks like a pin that goes in the wheel hub.
Did you absolutely find that INSIDE the trans, or did it fall off while you were checking around?
 
smooth pin. i dont see any spot where it would go. this is my second time taking apart the tranny, i dont know what gears are forward and what are reverse
 
Yeah, that would make sense. If there is no pin in one of the wheels, it would just slip.
 
maybe the threads broke off causing my tmaxx to rev without movement? when i opended the tranny last time(the same way) that pin didnt fall out
 
When you were running the engine and looking under the truck, did you make note of whether or not the driveshaft and the rear axles were turning, but the wheels were not? If that's the case, it's the wheel hub.
 
Hold the center rear drive shaft and try to roll the tires on the ground. If they both turn, the axle pin is missing.
 
they turned when i lifted the wheels off of the ground, on the ground nothing moved, thats what made me think it was a tranny problem
 
Since you had everything apart to swap out the diffs, just take off both rear wheels, and look at both hubs to make sure the pins are in place.
 
an i swap reverse gears for forward gears, and just get rid of reverse altogether?

all the pins are in place
 
nm that wont work rolex. i was thinking i could take out the reverse gears and swap them to work as foward gears. but i just looked at the tranny and that can't be done...i think that pin is the cause of my problems though
 
I've never done it, so I don't know what needs to be changed. If you want to give up reverse and change it to FOC, you'll have to wait for someone who's familiar with it.
I looked in the manual, and I can't find a smooth pin like the one in your pic, so I don't know where it goes, or where it came from.
 
can a foc be done with parts i already have or would i need to buy a kit?
 
There is a kit, and it isnt all that expensive. It makes the truck move so much more smoothly its not even funny. No more clicking at partial throttle.
 
There's nothing in your photo to show the scale of the pin you found. Is it smooth on both ends? If one end is rough, it could be snapped off.
The only thing I can find in the trans that's close to that pin is the yolk pin, towards the bottom left of that page. It connects the trans output to the drive shaft. It's on the outside of the trans. If it's snapped, and only the grub screw end of it is left in, that would cause the problem. Remove the yolk pin to make sure it's intact.
 
ill try and buy that and see what happens. why not have an all out speed demon i already have the .23 ill get that kit and see if that fises my motionless tcrapz:P thanks for the help you all...i woulda cursed me by now lol

Hmm, couldnt the yoke just pull off then?
Click to expand...
Not necessarily. If it snapped slightly off center, it could have cut a groove while spinning, enough to keep it in place without being able to turn the drive train.
(IF that's the pin, it's the allen head end that would still be there.)
but you won't know without taking it out and checking it.
