I have a 2001 Mitsubishi Eclipse GT that my dad had just recently purchased for me. Everything was great. Then my dad took it to the shop to have the oil changed and the transmission flushed because he wasn’t sure when the previous owner had done it last. The night we got it back we drove it around and the car makes almost like a really big vibration some times, and you can definitely feel it in all of the seats, drivers seat the most. It’s almost like it makes the car shake a little bit and you can hear it too. And it only seemed to do it from anywhere 30-45 miles per hour and when u would let off the acceleration it would stop and its random it happens every once in a while for 15 seconds or 2 seconds and at 30 mph or 40 mph or 37 mph and ext. And it had never done this before and we had driven it quite a bit and we would have noticed if this was there before. So we took it back to the shop and they said the transmission fluid was low so they put more in it and we took it home again. It still made the vibration in the whole car, so we took it back again and told the mechanic to go for a ride in it to feel it and so we did and of course the vibration happened and he said he had no idea what it was? So he took it back again and said that maybe the machine that flushes the transmission might have gotten trash in it somewhere so he would flush the transmission again to get it out if that’s what it was. And he called after that, and said that he took it for a ride and it was still doing it. And we have no idea what this is? We haven’t even had the car for a month yet and no one even the mechanic has no idea what it is? Can you PLEASE help with any information possible to help fix it or to know what’s causing it it would greatly be appreciated!!!
Thank you sooooo Much!!

Had a very similar problem with a 2000 Mitsubishi Galant! The sound was during accelleration and at about the speeds you mention!
I immediately thought it was the CV joints for the FWD.
My regular mechanic changed 2 engine mounts he thought was causing the problem. The problem persisted, so we took it to the dealer.
The dealer had 2 "master" techs drive look and listen and they said it was the axle, although they couldn't say exactly where or why.
We had the axle on both sides rebuilt, which includes the CV joint and the problem is gone!
Price: $400.
Hope this helps and good luck, these car diagnostics & repairs can be challenging!

The ASE mechanic who suggested it could be a multitude of things is quite right, and diagnosis here is no small order. Still, I am not much a believer in coincidence and I would look toward things that might have been affected by your service. Sometimes for example a transmission flush can shake loose debris inside the transmission from the power flushing and clog something up inside. As far as the oil change goes, I cannot imagine much that could be affected there, and the only thing internal to the engine that occurs to me that is in the oil bath would be the crankshaft counter balance, but I don't see how that could have failed.
You can narrow it down a bit though. For example. Put the car in neutral and rev the engine up to various levels and hold it at those levels for a couple of minutes--say 2000 rpms for two minutes, and 3000, for two minutes and 4000 for two minutes and see if you get the virbration. If so, then of course it is engine related, as in neutral neither the drive axles nor the transmission is operating.
Next, take the car out on the road again. Get it to vibrating and shift into neutral to drift the car while keeping the rpms up. If the vibration stops, then you have likely eliminated the drive axles as the problem as they are still turning even when you are drifting (although the condition could only be a function of when the axles are being torqued by the engine). Still it gives you some clue.
That would lead you back to the transmission again, or possibly a motor or transmission mount that has partly collapsed and allows this sort of resonating at various speeds because the engine and/or trans are no longer being properly supported at the designed angle.
I am sorry I cannot be of more help, but as the certified mechanic said, in some cases one really has to look at the car.

sounds like bad front axles,or tires need balancing, or the combination of both. Check to see if the timing belt has been changed. Most cars have a balancing shaft belt on them and if it is installed incorrectly you will get that vibration.

It is going to be hard for anyone to say on here what your problem really is. That is one of those things that I would have to drive the car myself to determine what the problem is. It could be a multitude of things. That is my honest answer.

way too many dummies guessing at this one. this is the exhaust shields damn. the two positioned hose clamps on them to rather them down or take them off thoroughly. this happens to maximum Eclipse and Galants.

bad axle sounds good....i would have gotten major tune-up too...fuel filters...plugs...wires...the whole bit..get wheels balanced
