I am in the process of changing the fluid for the first time in my F150 pickup with the 4R70 transmission. When I pulled the pan down, there was a off-white (maybe yellow)plastic object shaped somewhat like a child's top with an O ring around the bottom of it, lying in the bottom of the pan. I cannot figure out where this goes or what it is called or used for in the transmission. I have posted pictures of it on http://photos.yahoo.com/schue54. Any help would be appreciated.

I think you meant this, you had a period after it...

Just throw it away it does nothing or save it for a keepsake. It kept the dust and dirt out of the tranny in the filler tube hole during production. Do a search for info. I think it has been answered in detail before.

 

Thad,

Thanks for the reply. I normally do a search before asking any questions, but I was being lazy and in a hurry to get the truck on the road. Must do honey-do's. Thanks again.

Tom
