**Q: Is this for a automatic transmission**
A: This is just a seal it could be used for many applications you will need to look it up to verify fitment for your particular use, My application was as a rear tail shaft seal of the drive shaft yoke to the spline of the output shaft on an automatic transmission on a 2007 Ford E150 van with a 4R75E 4 speed Automatic in it. Hope this helps
