Welcome to TW...So you drove it after you drained it...what kind of fluid did you use?

Not sure WS would be correct for a 1st gen.

I always used Castrol Trans Fluid for import that said Toyota on it.

Manual?, was it gear oil?

OP has a double cab. They only came as automatics. Unless it was a manual swap.

I made a mistake and pulled the trans plug instead of the oil plug and emptied the trans fluid by accident, i drove maybe 5 miles to get some trans fluid and filled it up and have zero issues now, but my question is should I drain the trans fluid again and buy high quality fluid? I went down the road to the store and got some random trans fluid.

No matter which you decide to do, before adding any additional fluid verify you are adding the correct fluid. Pull your transmission dipstick and look on either side of it. It will be stamped with the type of fluid to use.

Once you know which fluid you should be using, see below -

If you do the drain and fill again, see my post here

Just do a drain and fill. No machine powered flushes, just a good ol' drain and fill. That's it. Not going to hurt it, everything will be fine.

When I did the 4WD conversion, I took a 1999 4Runner A340F (which was drained at the salvage yard), dropped the pan and replaced the strainer (you don't need to do this at all, the one I pulled was clean) and buttoned it back up. Refilled using the steps below and its been running without issues.

Your 2004 takes ATF Type IV but always, always check the dipstick. It's stamped on the dipstick which fluid to use.

This is the process for a drain and fill:

Steps 1-5. Once fluid level registers in the COOL range, stop adding and go drive. Get it up to operating temp. Once at op temp, keep the engine running and re-check level. Continue adding until it is within the two dipstick marks in the HOT range. Once in that range, check for leaks, done.

Or, you can leave it as is. The choice... is yours.

If you decide to just check and fill correctly since you already filled - see this post,

I'm adding this as well. There is always hesitation when it comes to servicing your transmission fluid. I blame all those videos out there screaming about sludge breaking loose and gumming up the valve body, etc.

Anyway, this is the process to use when "Checking" your fluid level (not adding after a drain and fill but checking only):

*NOTE*: Always check the dipstick for the type of fluid your transmission takes. It's stamped on the dipstick.

Love the part how toyota says if it smells burnt or is black, REPLACE IT.

Listen to the factory, imo. If it smells burnt, drain and fill.
