Default Good ideas to clean out converter?

My 3-4 clutch pack went bad and my fluid was nasty. Didn't have any hard parts break so I should be able to clean out the converter and be okay.

I tried pouring in clean fluid then dumping it back out but that isn't working really well.

Anyone have any idea's how to clean it real good pretty easily?



I was trying to avoid sending it in and spending $250 to clean it.



Or does someone know a shop in Dallas that can do it?

Usually when you need to clean out a converter they cut it open clean and inspect all the parts then reweld it together and rebalance. I know circle D is around houston and thats a bit of a drive but they can probably help you out

I want to avoid cutting it, just wanna clean it. Curious if there is a way to do that without cutting it open. It doesn't have debris in it, just nasty fluid.

Same thing happened to me about a month ago, when I called a local converter shop I was told the only way to clean it was to cut it open. For ~ $120 it sounded like a good idea. Was done the next day.

I always wondered if running solvent through it until clean would work.

Dont think there is a very good way to do it, without a cut and clean. There are just too many places for things to get stuck in there, and its too easy to wipe out a trans with crap.

I dont know who's stall you have, but IIRC, when you get a C & C, they will replace bearings or any worn parts while they are there.

It's a Yank. But shipping it to Yank is around $100 and will take 2-3 weeks with the holidays. From what I understand anything that has to be replaced I will be charged for so with shipping etc it will cost at least $250 through Yank and that's a 1/3 or more of what I paid for the entire converter, not liking that idea too much.

It's at the shop now, dropped it off this morning. They were showing me some of the factory lock up clutch frictions they had laying around. Those things are a joke, I am very curious to see mine in my Yank.

The frictions they showed me that are for OE applications were very thin, I have no idea how they hold under cruising much less someone locking them down. Again I am very curious to see the difference in mine vs the stockers.

keep us updated on the Yank improved parts, I ran a Yank ST3600 9-10 years (75 k miles) and 3 sets of 3-4 clutch packs with no TC problems, now on a Yank SS 4000 about a year , but only about 600 miles

Did you have your converter cut and cleaned when the 3-4 clutches went out?

I just called the converter shop and they said it was cut open and headed to the parts washer already, so I told them not to put it back together yet that i'm on my way to come check it out.

A place called PTI around the corner from my house. Turns out a buddy uses them and he tunes and does a lot of builds and has had good luck with them. They have a ton of stuff laying around to build converters and showed me all the parts and equipment used. Pretty neat stuff.

Well just got back from the converter shop, mine was sitting there cut open waiting on me. The parts and build quality in the Yank converter are far far superior to the OEM stuff they had laying around.

It was nice to see first hand the difference's between the Yank and an OE converter.

Totally late and after the fact at this point, but I have seen people drill and tap a hole in the side of a converter and flush with solvent. I don't know about the small balancing issue that comes with the plugging of the hole. Just putting it out there...

I had heard something about that and it does seem like a good idea except for like you said the balancing part.

I wanted a cheaper alternative but after thinking about everything I knew I would never stop being paranoid if I didn't have it properly cleaned so I said screw it I'll take it in.

So after you put metal shavings in the converter now you clean it? That sounds like a horrible idea. There is a reason why they cut and clean them and do not flush them with solvent or fluid.

Not to mention if you drill into a turbine fin, lol, or the stator.

Yeah, all of that is possible and yet the first time I ever heard of it, it was offered as an alternative by a salesman at BTE who said lots of there customers have done it. He didn't say to do it, he just said people do it without issues.
