I went to go and change my trans fluid on a 2001 trailblazer 250, and I find this:



Yes, that bolt is jammed up against the frame. Now, is this supposed to be like this? How do you undo the plug to drain the fluid? Im a bit confused lol! Thanks.

 

It uses a jamb nut. You loosen the bolt nearest the tranny, then the long bolt going into that (by the cvt cover)you tighten until you can get the jamb nut out. If you PM (private message) me your email, I can send you a copy of the instructions from the service manual.

 

I'm trying to see if I can just post the picture from that page, but it doesn't seem to want to cooperate. Hopefully, I can get that on here for you. It's a lot better at explaining it than I am.
