Help: Torque Converter drain plug - 89 LTD

XJBucko said:

Whew, I've been reading tons of threads on how to flush the trany - not a pleasant experience for the comprehension challenged.:smoker:...

A few threads mention that some torque converters have a drain plug. Would my 89 LTD likely have a drainable torque converter? If so, I'm not exactly sure what I'm looking for, and where to look - presumably I might have to crank the engine over to to get the converter into the right orientation for draining? Does that make sense?

Never heard of or seen a torque converter with a drain plug.

You can do a home flush by getting a 5 gallon bucket (empty) and buy four or five gallons of transmission fluid (of your type) and pouring it into another clean 5 gallon bucket.

Remove both transmission lines from the radiator, extend them with extra hose. Crank the Jeep, put it in Neutral and watch which line flows out and which line sucks in. Drop the suction line into the new fluid bucket and the other line into the empty bucket. Let the engine run until you see clean fluid coming out of the discharge hose. Shut it down and put the lines back on.

With the engine running and up to operating temperature, transmission in Neutral check your fluid at the dipstick and add new fluid to fill level.

not gonna work, the return line doesn't produce suction like that

have you actually done this 2 bucket method yourself? i'm guessing no because the trans pumps fluid through the cooler and back into the trans, there's no suction involved
