Default Question on converter flushing

Hi guys, I have one of my old TCI converters that has been sitting in a box for 20 years with a sock stuffed into it to keep out the squirrels. Sooooo, needless to say it should be flushed before I put it back into use. How do I do that, or if it goes to a shop, how should THEY do it?

Converter technology has changed a great deal in 20 years... I would have the converter opened and serviced for your current combination. Beyond that, most converter shops would cut the unit open for inspection and cleaning

You'll never get all the small metallic debris out of a converter by flushing it.

It can be drilled and flushed and if done properly it will be nice and clean when its done. If you are just looking to get the old oil out of it , thats what a good flush will do. If the converter was removed from a dirty trans or one that has metallic debris , you may want to send it out and have it cut open and cleaned properly.

Thanks for the replies! I believe the converter came off a good trans, but that was a long time ago to recall. What is a fair ballpark price to open and inspect a converter?

I think normally 250.00 is where it starts with most companies to cut clean and reweld/balance.

Hutch, where is the best spot to drill a coverter. I drill one a long time ago when I was young, stupid and lucky, but if I tried it now I would definately screw something up internally.

If there is nothing wrong with it $75 for 9.5-12 inch units. Smaller units and larger units are more. Anything more than that without adding parts or hub changing,etc...is just a scam. It takes about an hour to do.

If you don't know the converter inside don't drill it without opening it.
Flushing just stirs the stuff around there are too many places for it to get stuck I don't suggest it. I have seen flushed out converters cut open the next day over a problem and the transmission was clean. The gunk builds up on the outside a 1/4 thick. Fresh fluid breaks it down and you have fine metal crap floating around inside there.

There was a local shop that would tap a drain fitting and pressure flush a converter while it slowly turned the internals. They did one for me several years ago, Never had any problems out of it.

Put a remote oil filter setup in the oil cooler line,this will catch any debris from the converter before it gets to the 'box,you can then change the filter after a short time or even remove the remote stup after a while if you wanted to. I've always done this if I buy a secondhand converter,a remote filter head,filter.fittings and short lines will cost less than a flush out and you can reuse the filter setup over and over.

Ive had converters Loaded with metal, flushed them then cut them open. I was shocked and surprised to see they were spotless.

So cutting , cleaning , rewelding , rebalancing a converter for more than 75 bucks is a scam? Unreal.

I would say charging $300 for an hour of labor is, I have this policy that I try to treat people the way I want to be treated so I charge what I consider is fair, $300 is definately nowhere near fair. It usually forces people to buy a new converter. This is why the market is flooded with used dirt cheap useless converters. People see a converter they can get for $450 or figure it will cost them $300 to repair the one they have and they usually buy new. The $450 converters aren't worth the time to install in any race application. Most of them are so inefficient and cheaply built they raise transmission temperatures so bad that people think their transmission went bad.
