I bought my 06 tl at 74k 4 months ago

The transmission has been WAAAY over filled this WHOLE time, didnt notice until about 1-2 months ago..im talking an inch or so

The car seems to be running great for the most part. I've read that messing with something like this can POSSIBLY cause more damage. I do NOT know how long it's been overfilled like this
currently have close to 90k on the vehicle..
any suggestions?

I could be wrong, since I've only ever dealt with manual transmissions, but I thought its impossible to overfill a Honda transmission. At least it is for the manuals. The fluid will just leak out everywhere if you try to overfill it.

How do you know yours is overfilled?

TacoBello

Having too much engine oil is bad for your engine. I've NEVER heard of someone having too much tranny fluid though. I guess maybe there's a first for everything

Drain it a bit and don't sweat it. Minus the fact those transmissions are finicky a bit too much is better than too little.

Besides, it doesn't take much to "overfill" an inch on the gauge, less than you probably believe.

Its about 3 inches over filled..should i drain it, or siphon it? Also, should the car be on; if you say siphon.

Dipstick tells you pretty straightforward haha..It's about 2-3 inches Overfilled AT transmission

Jack car up, remove transmission under cover, loosen drain bolt (not remove) until fluid starts leaking steadily. Let it leak out until you're at the right level, tighten back up to stop leak. No mess.
Takes longer obviously letting it leak out but meh

OR

Remove the drain bolt completely, watch fluid gush out, and watch everything get messy when you try to put the bolt back in to stop the draining. You'll probably drain too much accidentally by the time you get the bolt back in.

OR

Remove the drain bolt completely, and let everything drain out and do a refill.

You said an inch at first...

But I digress, as GP16 said, loosen the drain bolt. If you want to unscrew it more, always keep pressure on it because once it starts flowing if you remove it completely you'll make a terrible mess trying to put it back in while it's draining.

I didnt realize i said that, i think i was editing and missed that. Its 2-3 inches.
The drain bolt..is that up top? or under the car?

polobunny

Under the car, near the driver side wheel, hiding under a protective plastic shroud you have to unbolt/move out of the way.
Look for 3x3 drain and refill procedure on the forums, that will show you where the drain bolt is located and how to access it.

At that point, perform a drain and refill if your going to go through the process of removing the bottom cover, and loosening the bolt.

I hate cars

Agreed. At that point you've done 80% of the work of a drain and fill.


Usually an overfilled automatic will result in leaks, especially from the axles in a FWD or the output shaft in RWD. If it's really too high, it will just puke out of the vent tube all over the top of the transmission the first time it gets hot. It's probably fine just the way it is but if you want peace of mind a drain and fill might help.


On most cars you just loosen the clamp on the most convenient cooler hose and start the engine for a few seconds to lower the level but unfortunately Acura has no rubber lines on the base model.

thanks for all of hte responses..its defnitely not leaking, but its waaaay overfilled. Had like 3 different shops confirm that. None of them would drain it because of the liability with transmissions. Looks like I'll be doing a 3x3
