How much to fix this transmission issue?

2001 Honda accord 4cylinder It slips from 1st gear going into 2ND gear. When I start from 0 mph it gets to 20mph then the rpms go really high so I have to let off the accelerator and let the gears change.

How much can I expect to get charged?

2 years ago I blew my engine on my 2003 Chevy trailblazer and they charged me $1,200. Should I expect something like this or less?

Thanks guys. It is my daily driver so I really want to get it fixed but am a poor college student

Crank, but no start Honda Accord Lx 1990?

So my Accord was stolen last week, and now that I've recovered it, with for some ridiculous reason only the hood rod and a radiator hose missing it won't start. The thieves removed the covers to my steering panel and left wires exposed, I managed to plug them all back in but now I crank and I get no sign of life. However, my horn and brake lights to activate. What could this possibly be?

Where can I find car parts for new cars online?

I'm looking for a rear door for a 2014 Honda Accord and can't find one anywhere? I also need a quarter panel I found one but it was almost $600. If you can help me find a door for a 14 accord 4 door it would be much appreciated.
