AC Delco 1259475 Oil Filler Tube Seal – Fits Chevy S10, Blazer, Tahoe & More (1982-2013)

This little AC Delco seal (part 1259475) is actually the automatic transmission dipstick tube seal, and it fits a massive range of Chevy and GMC trucks and SUVs from the early 80s all the way up to 2013.

We're talking S10, Blazer, Tahoe, Silverado, Suburban, and many more.

If you've got a transmission fluid leak around the dipstick tube, this is likely the culprit.

It's a genuine AC Delco part, so it's a direct replacement for the factory seal.

It's brand new and ready to stop that leak.

Check your vehicle specs, but this seal covers a ton of models with transmissions like the 4L60-E, 4L80-E, and more.
