For anyone with their transmission out of the car….Now is a good time to swap out and change that transmission filter. In the future we need to do a lot more threads and write ups on working on the transmission, how to remove it on a lift and jack stands.

When I first opened my transmission I was very intimidated about touching anything in there. The fear of the unknown can make a lot of us timid. Well since opening the transmission for a second time to remove my welded differential and put in the TC LSD differential, I decided to go ahead and change the filter too.

It’s extremely easy. The oil pump is held on by 3 (8mm) bolts. I used my new digital 3/8 digital torque wrench to determine their set torque specs. 9ft/lbs. B93B6242 D4F6 4818 BE56 9FCCBB863A9E
once unbolted, it’s simply lifts up and at an angle and comes off with the filter attached. 99F815C5 186E 4E4D 92FA 327CF80498F7
As you can see the magnet is pretty nasty with metal 55712A81 7EF1 407B 8B58 606F69767F85
Here is the part numbers for the new filter and seal, which if you notice are also the same parts for the GM 6T70/75E3C4EDDB 7CC1 4773 8061 D3E5EE222364
Removal of the filter is easy, slides off with a little force. Then put the new seal in first 60EEE4B4 D361 475A B258 3D349D46FED4
Then attach the new filter. BE2E78F8 0E19 4C3A 9048 F36EEA03FE2E

Reinstallation is the reverse order. Slightly angle the filter in first and slowly lower the pump onto the chain and gears. Torque the 3(8mm) bolts to 9ft/lbs. A10F0B37 17F6 4BC8 A9A5 D23DFC4BA003
wallah! I’m going to use my mighty vac and remove all the leftover fluid in here, maybe about a pint combined between the two sections of the transmission. That’s it!

With so many parts the same as the 6T70/75 I wonder if there’s a built 6T70/75 already out there and what if at all would need to change to get it into our platform? If our bell housing bolt configuration is different…I wonder if it would be just a simple…swap of the bell housing and if everything internally is the same, just the outer casting different? Hmmmmm?!

Dude, you are definitely going where no man has gone before lol. Great pics and explanations. I'd need a dedicated garage to do all you've done, but my S550 takes up all my extra space lol.

Bc my engines new capacity far exceeds the transmission’s I may end up removing/swapping several transmissions in the near future, realistically, so I’m pretty confident the process can be streamlined and presented in a simplistic fashion. My weapon of choice or only option I should say will he jack stands lol! But an engine hoist is needed for sure. Either you buy one then lend it to all your friends bc you hardly every need it…or you have a friend that already bought one and you get to borrow it for free like me lol.

Yeah, I'm the guy that bought the engine hoist and used it twice in 5 years lol. As it takes up space in my cramped garage, even though it folds up.

I almost bought one and I was like damn I’ll never use this thing again but ran into an old friend who had one. Nice to have but yeah it’s a space invader lol! Probably why my friend hasn’t asked for it back in a few months

Haha! I bought one and have figured out all kinds of other purposes for it. In a couple of weeks it will be holding up my riding mower while I change the blades and belts.
