I have a 92 accord wagon lx auto.

I was driving 55mph when the car starting jumping back and forth between 3rd and 4th. The car did this for a few minutes after I stopped to check for any fluid leak (no leak).

Now the cars current state is as stands.

The D4 light is always on no matter what.
When shifted into D4 , it's stuck in 4th gear
When shifted into D3 , it's stuck in 4th gear
When shifted into D2 , it's stuck in 2nd gear
When shifted into D1 , it's stuck in 2nd gear

Every time I come to a stop sign now I manually put it into D2 or 1 , get up to speed , then put it back into 3 or 4.

Funny enough it actually feels like it drives better and smoother this way. lol But obviously something is broken and needs to be fixed.

Some googleing says TCU and shift solenoids , but I'd figure I'd ask here as well. Keep in mind I'm an engine noob please.

Sounds like the shift solenoids. Test them by running 12v straight from the battery to the solenoid via test wire. You may have to remove them and clean then and replace the filter/gasket which is a dealer only item.

Check your fluid for color, consistency, and smell. If it smells burnt or nasty, and if it's a brown or really dark red color, your going to need to rebuild the transaxle.

Ok problem solved. I changed the tcu with another 92 accord lx wagon I found at the junkyard. Even though the cars are identical the tcu's are different part numbers.

Either the donor car had it's replace or my bad one was replaced. Either way , it's back to the way it was except it shifts earlier from first to second but I truly don't care I'm a slow driver and rather have it shift sooner then later.

Now to figure out why my torque converter is backwards , but that issue already existed and I'll make a different thread for it.
