Okay so I own a 2000 5.2l 2wd durango auto. It currently has 193xxx I got an engine code that gave me po740 I looks it up it and says something with the over drive I knew this was coming because 1-2 there was slippage. Should I just replace the whole transmission because right now it's a point that it could go only 25 mph. Another thing is recently as I want to start it you only hear one click and that's it, the car doesn't start, I replaced the Battery and sparks and coil almost a year ago it's been sitting for more than 4 months I turn it on every here and there. Lastly my main concern of all, when I brake it seem to me that one of my front right tires locks on me, I do have abs and I replace the tires and pads, rotors, drums. Took it to so many mechanics no one can figure it out because it makes it sensitive that if I press firmly ok the break no matter what speed I tend to go from 5 mph or up it would lock and you feel it my abs light never goes off when I brake light that. Thanks for reading this I appreciate it for helping me
