How much oil did you put back into the transmission?
I'm sorry the website was down for a while, I couldn't access anything
It takes about 3.5 qts from removing the pan and changing the filter. Are you sure you filled it up through the dipstick tube and not the engine oil fill tube next to it?
Only the engine oil tube sticks out, the transmission tube has locked cap more recessed in the back of the engine.
Sucking out 8 qts doesn't make since, are you sure you didn't suck out the engine oil? The transmission cap has a lock on it as long as its installed properly. Then engine oil tube looks the same but with just a pull out plug. I'll post a picture and you can view it tomorrow.
In this picture, the arrow is pointing toward the engine oil dipstick tube, not the transmission fluid dipstick. You have to remove the air cleaner and look deeper more towards the center back of the engine to see the transmission dipstick. You probably sucked out the wrong one and added transmission fluid to the wrong dipstick. It actually happens all the time to a lot of backyard mechanics.
It doesn't look like there is one but here is another picture. It is very hard to see
You can kind of see the longer higher engine oil tube in the left side of the picture. The transmission dipstick tube has that style cap on it and only that style cap.
The transmission dipstick cap says "MB workshop only" printed on it.
