I have a problem with my tranny. when shifting into the 1/2 gate the gear lever sticks. when shifting into all the other gates, it's completely normal. This happened thursday while driving on the highway. even if i push the lever over to neutral in the 1/2 gate it's sticky trying to move it back. I'm pretty sure i have a leak in my lever area to begin with and i unintentionally let all its (extremely dirty) fluid out yesterday trying to fix the leak.
so:
1. What could be causing my sticky 1/2 gate?
2. Can i fill the shifter part up from the shift ****?
