Transmission is getting replaced; what to expect?
Beware: Long rant/story.
Ill start off by saying that today has been a stressful day for me. Last week I brought my car to a local mechanic to fix my front passenger window(wouldnt go down). Since I needed an oil change and I'm about to hit 50000 miles, I also go my transmission fluid changed and a new belt put on. This past Friday I got my car back, and it seemed to run good. Saturday I went out with some friends and my car was acting very oddly. I would press on the gas and it would rev, but wouldnt really go anywhere. Sunday I let my car sit in the drive way, thinking that what ever happened would go away. Monday I drove my car to school and halfway back to the shop~~ about 25 miles. Every time I would stop at a light for more than 5 seconds, my engine would just stop. I ended up pulling over and calling AAA because I didnt feel my car was safe enough to drive. After getting it towed to the shop and leaving it over night, they called this afternoon with great news. Who ever worked on my car didn't correctly wire the transmission after changing the fluid and my transmission is shot. They said that they will cover the cost of a new transmission, but I honestly cannot trust them now.
What should I expect with this new transmission? Will it lead to other problems with my car or not really? I'm sure you all can understand how I'm feeling right now, especially as this is my first car and I've only owned it for 3 years.
