Trans Fluid Change?

[POWERED SPARKLESS]

I think that this should be a sticky in the tech files if a MOD would filter a few posts, and put what is needed in there.

So I'm going to change the trans fluid in another Tourqushift, and can't remeber how much Mercon SP is needed The last couple ine and a friends trans I've changed I bought a case of fluid, filter PN:3C3Z-7B155-BA internal, and filter PN:3C3Z-7A098-AA frame mounted, than just return the extra fluid.

My problem is the tech at the dealer today told me all I need was 6 quarts but I'm sure we put more in than that. Did I do some thing wrong in the past?

Just did mine last month. It took 8 quarts (pan drop-tranny fluid change)

You don't flush the converter? Over half your dirty oil is in there.......

If it only took 8 quarts with a pan drop, you must have been low on fluid or had it at a big time angle. Mine takes 12 quarts when I change the internal filter and drop the pan, and every other Super Duty I've seen takes about the same.

If you change the fluid at the recommended intervals, you're fine not flushing the converter. The fluid is actually very clean if you change it and the external filter every 30k, hence the reason for that interval. It would cost a fortune to flush all the old fluid out with that frickin $5 a quart mercon SP.

I did my, pan drop, change according to this:

....and in the end 8 quarts was all it needed according to the dipstick (on flat level ground)

There's no plug in the convertor to drain it. The only way would be to pull the convertor and suck the fluid out through the shaft hole.

I was thinkin that I put around 8 quarts in and saved one just incase.

You have to go to either a dealer or instant oil place that has a tranny machine. They attach your tranny lines to it and it flushs the entire system.

Correct, but I believe the OP wasn't wanting to spend that kind of coin.

Nope, my buddy is just like me. Very broke $150.00 is more than enough on a fluid change.
