I was driving my 2001 civic ex automatic the other day and out of nowhere it revved up(transmission slipped). I continued on to where i was going with no issues. When I got home I checked the fluid and the level was ok and the fluid seemed ok, not burned. The next day i started it up and drove up and down our long driveway a few times. It was slipping and slow going in to gear. I left it running and checked the fluid again and looked around to see if any sensor wires were unplugged. when I got back in, it would not go into any gear, so I pushed it back to its spot. The next day I came out and started it and it went into gear and would move, nut transmission was whining fairly loud. No check engine lights on the dash.
Any thoughts?

Trans is known to be the weak point on the 01-02. Get a trans from an 04-05

If P0730 isn’t showing, I’m betting it’s stored. Put a code reader on it anyway.

I checked and there were no codes
I picked up a transmission from a guy who said it had been rebuilt with a little less than 14,000 miles on the rebuild and the car was rear ended, so he pulled the trans before scrapping the car. I started on pulling the transmission today. Lots of metal on drain plug and fluid was dark, so I think it was done, especially with knowing the history with this year transmission. 199,000 miles on the car. Contemplating swapping the engine out with a JDM while I have the transmission out. It burns oil and there is a leak that looks like its coming from the head gasket.

burning oil and headgasket are two other common issues in this car.
Oil is from carbon deposits sticking to the oil rings and collapsing them.
Headgasket is expected to fail every 100k miles or so.

I've never seen a head gasket leak oil externally. You should look at other locations for the source.

Now that I have the transmission out, I can get a better look to see where it is leaking. Possibly back side of valve cover. I would like to fix this, the leak made a mess of the transmission. Replacement transmission doesn't have the locating dowels in it and hard to get the old ones out without deforming them a little , so I am going to make new ones. (I'm a machinist)

There is also a plastic plug for the end of the camshaft that is a known oil leak spot. Only other common leak would be VTEC solenoid (if it's not the valve cover gasket).

crabbydad

thanks a lot, appreciate it, I will check those out.

crabbydad

a lot of oil around the solenoid and the camshaft plug, so I'm replacing the solenoid gaskets and cam plug. Good call BrotatoChip, Thanks!

Might as well do the valve cover gasket as well!
