Transmission Filter Change ..Lots of Pics

2003 Toyota Tacoma PreRunner 3.4, Automatic. Approximately 149,000 miles.
Purchased truck new. At around 50,000 miles I gradually switched out the original fluid with Amsoil full synthetic. At every oil change, I would drain what was in the transmission pan and replace. This was usually around 3 quarts.
Decided to replace the transmission filter for peace of mind. Big shout out to Tim (TW member Timmah) and his videos. I think I watched this one about 3X.
The three magnets had the normal black, clutch material, but surprisingly the bottom of the pan wasn't bad at all. Like Tim pointed out in his video, the outside of the strainer body was covered in the "slimy" dark material similar to what was on the magnets but not as thick.

TIPS from my experience
I used the abrasive wheel buffing set (see link) to remove the old gasket material from the transmission pan. Can't recommend this enough! The gold colored ones make easy work of the gasket material.
For where the pan mounts on the transmission, I used what Tim recommended which was #000 steel wool. This gave it a shiny, clean surface.

DID YOU KNOW??
That on the transmission drain plug is stamped T IV. I can't believe I've never noticed this before and thought it was pretty cool. Picture below.

Great post happy to see such a great write up and proud to be on this forum.

 

I'm I missing something?
What's the significance of T IV on drain plug?

 

Helpful hint… take a screwdriver and dimple the edge in 2 or 3 place that projects from the filter inlet, the bathtub shaped opening. The reason for this is simple, that opening drops down so low into the pan that it almost contacts the oil pan… some knuckle head will use the flat surface of the trans oil pan as a jacking point and collapse the pan to where the pump cant get any fluid, now you need a transmission.

 

My thoughts exactly. Thanks OP, you clearly put a lot into this write up and I appreciate it
