AOD grinding before shift??
 

I just got done installing my aod and it is making a grinding noise right before it shifts - what is this?? I am fairly sure the tv cable is set right, and the fluid level looks good......

Wow your AOD is being really nice to you. At least it's warning you of a potential problem; mine didn't! How does your fluid look and smell? Brown & burned? Red & sweet?

A grinding sound before each shift, eh? Ooh boy, I guarantee if you take it to any transmission shop they'll want to install a totally new/rebuilt unit. Is it really before every single (UP OR DOWN???) shift the trans makes, or is it just one or two gears? I'd suggest you stop driving it until you can drop at least the valve body and see the contents of the pan. While you're doing that, change the fluid and filter. You'll probably also want to take apart & spray out the valve body with brake parts cleaner. If you've never done this it's a good idea to find someone to help who has, plus it'll help it shift quicker & cleaner, if it can be simple as this. As to what the problem actually is, without being there to hear it I could only make a stab in the dark. I hope it's not your direct drum and shaft stripping their splines out. Maybe you'll be "lucky" and find the torque converter's internal splines eaten away like I did.

I'm kinda hopeing its something stupid.... its a brand new Lentech... the fluid is still red and smells just like when I put it in....I went through all the adjustments and filling per instrustions before test driving, and this is what happended on the first test drive....

looks like I was something stupid or I am just paranoid - the fluid was areated and now that it isn't - it not doing it any more............I guess having my "inspection hole" in the floor open so I can hear everything, made it sound louder than if I was fully enclosed....
