Rated 2 out of 5 by from Be Careful The National Part #: 5208 SKU: 1428971 is the wrong part for a 1994 through 2004 GM 4L80E. This is the only transmission extension housing bushing listed for the 4L80E, and it was shown as being the correct bushing and seal for my 1998 GMC 2500 with the 4L80E automatic transmission. This is incorrect! The National 5208 bushing/seal kit has a bushing with 1.99" outside diameter which WILL ONLY FIT PRE 1994 4L80E automatic transmissions. The extension housing and bushing has been modified by the factory 2 times, once in 1994, to 2.015 " OD and again in 2004 to an even larger OD. The diameter was enlarged to provide better lubrication and longevity. I used the seal and threw the bushing away. With the online discount it was worth just getting the seal. National should list this kit by year, and Pep Boys should know better.
