I've been estimated at 2-3k.

Instead, I'm getting rid of all my aftermarket shit and selling the car before the transmission does die.

You've got an Accord LX, probably 100-120k miles, you might want to think about selling your car too. Your car appears to be a four door as well. You're driving a car with no ammenities and a ticking time bomb.

You might come to the same conclusion I did.
