Whats wrong with my tranny?

[JOHNNYMAXXIMA]

So I've been playing with my T-Maxx while I wait for parts to come in on my E. I got stuck in some bushes and tried to put it in reverse but it wouldn't go. So I kept flipping the switch back and forth to try and get it to go into reverse and it wouldn't go. I guess I could have walked the 10 feet where the truck was and moved it, but hey, I've got reverse and I wanted to use it darn it. When the truck is shut off I can see the shift rod going in and out of reverse really easy, but when the motor is running, it doesn't want to go.

I upgraded the shifting servo and that still didn't work, although if the motor is at a low enough RPM it would occasionally go. And just the opposite as well, if I'm in reverse, it doesn't want to engage forward either while the motor is running.

Has anyone heard of this before?
Do I need a new tranny?
Should I get rid of my truck?
How's the weather were you're at?
Do you like movies about gladiators?
Oh, sorry, scratch those last two. This is what happens when you're on disability and don't get out. :L: :P: :W: :C: :cry :cool:

Thanks.
