Transmission won't engage

I have a automatic 99 honda civic. To make a long story short I have gone through 3 different transmissions with this car and the problem has not been resolved. It started one night when I stopped at a red light, when it was my turn to go the car moved a couple feet but stalled after. It wasnt going into gear it just made a revving noise no matter which gear I put it in. But when I turned the car off and on again it moved a little and did the same thing. Took it to the family mechanic and was told I have a busted Transmission, didnt have the money at the time to rebuild so I went to a honda junkyard in Miami and got one for $400. Put it in the next day and it was perfect. But the next day it did exactly the same thing as the other. So I bought that one back and got another thru a friend of a friend that would not rip me off. And now this one is doing exactly the same thing. I really dont know what to do, I am a 20 yr old female going to college with a pt job taking night classes so I desperately need a car. He is a good mechanic, has worked on everyone elses car without a problem but I dont know if he's missing something. The check engine light has been coming on but I was told its because I have bad engine mounts, I plan to sell the car for something else but I want to get it running. Any suggestions will be greatly appreciated thank you

Respected sir, When we put in drive gear my car does not run even one foot.
When we put gear in D the car sound is changed, but does not work. My car is not moving. Kindly help

Dear sir, I checked transmittion fluid. Transmittion fluid is on good level.

97 civic auto transmission wont go into reverse and makes grinding noise when trying to put into reverse. All other gears work fine. Transmission was recently rebuilt.

I have a 1997 honda civic ex with automatic transmission that is giving me some problems. When I first start the car I runs fine with the exception of a rattling sound from the transmission. It will go for about 5-10 min the it will not go at all. When it stops working the tranny sound goes away. Iv been told several things it could be : computer, solinoids. Do you have any idea what it is?

I have a 1996 Honda Civic EX 1.6 L with an Automatic transmission. The problem I'm having is the transmission absolutely will not engage at random times. What we're experiencing is that it will start up fine and go shifting normally, sometimes a few feet sometimes a few miles, but at random times it just stops pulling all together no matter what gear you are in we get nothing not even a budge. We turn the car off let it set for about 5 minutes or so start it up shift to neutral then to drive and its ready to go again sometimes for a few feet or sometimes a few miles. We did notice a buzzing noise coming from the linear solenoid could that be a sign that it is faulty and causing the symptoms we are having? We did remove the linear solenoid and inspect it but we haven't done a resistance test on it and we are having trouble finding one somewhere in stock they wanted a $195 for one at the Honda dealership! Please help if you can we need this thing fixed ASAP thanks a lot in advance!

After it sits a while it go's again, but repeats. Can someone help?My 95 Honda civic is giving me problems, more-less the trans. It runs fine when its cold, but after it gets warm it wont "go" anymore. Its like its not engaging anymore. I have heard all things from the shift solenoids to the tcm. Can someone please shed some light? Should I change the fluid and try the brake fluid trick? What would cause it to slip, torque conv?
Thanks.

And if the fluid and filter are fresh and new, then would I look at the torque converter?

So, then would it be safe to say, that it would probably be in my wallets best intrest to just get a used one or refurbed, and save time & $?

Right on. Thanks for your time and brain, bro.
