Trans problem with a 1996 96 Automatic Honda Civic?
I just bought this car about a month ago (used, obviously) and the engine light just popped on about an hour ago while I was driving. Then, immediately afterwards, I wasn't able to accelerate anymore, it just made the loud revving noise. Someone was nice enough to pull over and run some codes for me and these popped up: P0700, P0715, and P0740.
From what I understand (thanks to Google)...
P0700 just means at least one trans code was thrown, so that's just a standard red flag for a trans problem.
P0715 means there is a problem with the mainshaft speed (either is sensor/wiring is having problems or the trans is failing). That means I'm going to have to flush the transmission and replace the linear solenoid, whatever the heck that is.
The P0740 is a torque converter lockup malfunction. That means the problem is either because the solenoid is defective or it has an internally slipping transmission.
I never noticed there was anything wrong with the car up until tonight, except for faulty brakes.They didn't squeak or anything, it just felt like the pressure was dying when I was at a stop. A friend of mine was supposed to come by and measure the rotors and check the brake pads for me tomorrow, but for now I'm wondering could this be linked to any trans problems? I heard that in some cases for the P0740 there may be performance problems such as dying when coming to a stop after driving on the freeway and/or misfire-like symptoms. Don't know if that could be related at all or I'm just getting ahead of myself.
So my questions are...
About how much is it to flush the transmission and replace the linear solenoid?
About how much is it to rebuild or replace an automatic transmission?
Parts and labor, please?
Could the brake problem be related to the trans?
Is my understanding of the problems correct? My car didn't come with a manual and this is my first car with no knowledgeable car-savvy people around, so ANY information is helpful.
Thanks so much. A million stars for best answer.

I actually own one of those cars and the automatic transmission has a dipstick if you open up the hood and look closely by the passengers side you will see a yellow dipstick.Before you pull the dipstick out start up the car and shift the gears go from park to drive to reverse etc and let the car warm up a bit.Turn the engine off and pull out the dipstick use a clean cloth and wipe the fluid off then insert the dipstick fully into the transmission and pull out out you'll see two holes in the dipstick the fluid should be between the two holes.Note if you notice the fluid is real dark wipe some on your fingers try to smell it see if it smells burnt and if the fluid is low make sure you add the proper Honda transmission fluid, use a funnel to add some.Also if the fluid level is low check the dipstick when it's fully in the transmission does the dipstick move easily if so the rubber seal on the dipstick is no good and fluid may have been leaking from there.
If the fluid is dark or burnt change the fluid asap but it's probably a good idea to have the transmission flushed by a Honda dealership.You want it done by Honda bec they will flush it a few times like 3-4 times this is standard practise by Honda.Note before you invest into getting the transmission flushed etc you really should have a shop or Honda go over the transmission and run some diagnostic tests etc.
A transmission rebuild is probably about 1600-2500 bucks and a transmission flush at Honda dealerships in some places is about 180 bucks.The brake issue has nothing to do with the transmission problem.
Hope that helps and best of luck.By the way if you disconnect the negative battery post cable for say 10-20 mins it should reset the codes and if the transmission starts to work normally again then you'd know the problem is probably a electronic issue such as a faulty sensor or faulty wiring or a faulty TCM etc.
Maybe you run out of transmission fluid and that is bad. It will just rev but will not drive/run. There is dipstick above the transmission. Check if transmission fluid is on full or empty. If empty and you try to fill it up on full level with fluid, and it will still not run. Then you need to rebuild/change your transmission.
I am having this identical special crisis. I replaced the pace sensor and it's still occurring. My local mechanic is telling me the transmission wishes to get replaced, nevertheless, that's exceedingly high priced and i particularly believe it's an electrical concern. Can you please let me know the way this was resolved?
