I went to NAPA today to pick up a seal for the end of the transmission. I didn't think it would be a big deal - a garden variety TH400 right? Nope! they list 2 and vastly different sizes. I don't have the old one out yet, I don't like starting something and then looking for a part. If anyone has the correct NAPA part # , or the correct size in mm it would be greatly appreciated.
PS, they're really cheap - $2.50 and $2.80 for the larger size.
