I changed my trans filter and did the 3x3. I bought it used so I don't know what type of fluid is in there, it was changed at 65,000 on last owner and I changed it this weekend at 87,000.
I see that it has the jet pack kit (?) installed in the trans fill hole. Does this mean my trans is original? The drain bolt and like 3 other bolts have some blue paint on them.

 

I would say the trans is OE, but the oil jet kit was installed by the dealer to eliminate the 2nd gear problem found in the 2G and very early 3G TL's.
