Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Kit Parts work Fine Used one or both of the supplied parts for a transmission flush; they fitted my transmission cooler line/radiator transmission cooler fitting well (were of excellent quality) and I would not hesitate to use other similar products from this manufacturer/supplier.
