2004 Mazda 3 transmission problems
 

Hi, I hope someone can help me. I bought a 2004 mazda 3s, brand new in 2004. It now has 106K miles on it. I previously noiced that when i put the car in reverse (after it sits overnight or while I'm at work) it makes a very loud noise, bangs and jumps. Now all of the sudden, it wont go into 4th gear and when it does, it just revs and wont catch. i tried putting it in manual so i can keep it in 3rd gear, but after a couple minutes the MT Gear indicator that shows what gear I'm in, shuts off and it goes into automatic. is it a computer prob or a transmission problem or both? If anyone can help me or give me advice, i would greatly appreciate it. I appreciate you taking the time to read and reply. I love my mazda and want her back to normal! :)
