Dude your tranny is TOAST. /forums/images/graemlins/frown.gif
Just kidding... Okay not funny...
"Park" isn't actually a gear. /forums/images/graemlins/smirk.gif
You didn't specify what tranny either, but heres some pics of my TH350, they should all be very similar...
That parking gear drum you were told about is one of the drums in the transmission that has like over 16 little teeth on it... I highly doubt you broke all those teeth off.. I've broken one tooth off and I had to fix that parking pawl to get it to work again. ... so it probably is your linkage there...
When you put the linkage in park and it engages the parking pawl it wedges a little piece in between the teeth and prevent the drum from moving..
This picture shows it engaged. (in park position)
You can see where that shaft is skinny it won't engage the parking prawl while in R-N-D-2-1.... Only when you fully extend it to the park position that larger part of the shaft will push the metal piece in that slot and in between those teeth on the drum.
So your linkage might not be engaging it into park quite all the way.. Disconnect the linkage and shift the tranny into park by hand and see.
