Product Details

The ATP FO-11 is a direct-fit automatic transmission extension housing seal designed to stop fluid leaks at the rear of the transmission where the driveshaft exits the extension housing. This seal is engineered to meet or exceed original equipment specifications, providing a reliable, no-compromise replacement for worn or damaged OEM seals.

The extension housing seal plays a critical role in maintaining proper transmission fluid levels. A failing seal can allow automatic transmission fluid (ATF) to leak past the output shaft, leading to low fluid levels, slipping gears, and potential transmission damage if left unaddressed. Replacing a worn extension housing seal promptly helps protect the transmission from costly internal wear.

Key Features:

  • Exact-fit design engineered to OEM specifications — no modifications required
  • Seals the output shaft at the rear extension housing to prevent ATF leaks
  • Manufactured by ATP (Automatic Transmission Parts, Inc.), a trusted name in transmission seals and gaskets since 1955
  • Durable construction for long-lasting leak prevention
  • Direct replacement for cross-reference part numbers: 18470, 710487, 710671

ATP Transmission Seals and Gaskets are built as exact-fit, no-compromise replacement parts, making the FO-11 a reliable choice for professional technicians and DIY installers alike.

always a great deal here

easy site to use

I ordered the Dee Zee truck box rails and the price was the best on the net after searching. Also, fast shipping. I would recomend this site.

Quick

Your website said that these would not fit my vehicle. However, every other site says they do, including the manufacturer's website.

My order had a delay. I believe this was due to the fact that it was shipping from the manufacturer so I can't really blame Autoplicity. The customer service team did not originally respond to my first e-mail, but they did respond to me once I opened a dispute in PayPal and the issue was resolved. I couldn't find a better price on the part I ordered though (or anything remotely near that price for that matter).

Amazing Prices, saved hundreds over other Performance websites. Fast Shipping to top it off! Even with having to pay for shipping I saved $160 using Autoplicity over another "racing" website. Will absolutely do business with again!

The best pricing around and great shipping and communication when I reached out to them. Thank you Autoplicity!

Autoplicity offered the best internet price, and utilized Paypal for guaranteed customer service. Shipping tracking through UPS is accurate and customer focused. I'm very pleased with the retail experience, and will use Autoplicity on future orders and best prices.

Cheapest prices I found online! Ordered at 4:30 on a Thursday afternoon and had 'em waitin' on my doorstep by SATURDAY!
