My 2001 Honda CR-V with 74000 miles on it suddenly starting making this grinding noise when it's idling. Sometimes while I'm driving but mostly while idle. Does this sound like transmission? I am taking it to a shop on Saturday but want to know what I'm talking about when I get there as to not get taken advantage of...

If it's running rough, chances are that it's misfiring. If the Check Engine light is flashing/blinking, it is definitely misfiring. If that's the case, drive it as little as possible... Or straight to the mechanic because the more you drive it while it's misfiring, the higher the chance is of you ruining your catalytic converter.
Symptoms: Engine Light ON (or Service Engine Soon Warning Light)
- Engine hard to start
- Rough or erratic idle speed.
Causes: Dirty throttle body
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve.
there are no intake leaks, clean throttle body, adjust engine idle and
erase engine code. If the code comes back you may have to replaced the
Electric Throttle Control Actuator (Motor) to repair the problem.
I believe what you're saying is that after your car has been in park and you put it in gear to drive it makes a grinding noise for about 30 miles. I recommend checking you transmission fluid level and adding fluid as needed. You should do this fluid check while the engine is warm and car is idling. Since you have an 88 you probably have a lot of miles on it. I've had very good luck using Slick 50 High Mileage Automatic Transmission Treatment. A bottle of this costs around $15. If none of this works it may be time to take it into the shop or trade it in.
start your cr-v and let idle for 10 or so seconds in park. shut it off and check the fluid with in 30 seconds. if you check the fluid running it will read low and get overfilled. level ground is also important.
