One of the most popular transmissions, the 6R140 became a workhorse that could handle the power of the 6.7L Powerstroke. The dual planetary gearsets on top of large diameter clutches and larger output shafts put it as one of the best as you drive it off the showroom floor. 6R140 is an excellent transmission but like everything else, it does have some shortcomings. One of which is that age has a way of catching up to it after 100,000 miles and can cause failure if you don't catch it early enough. If you just bought a used truck and need to rebuild or refresh your current Superduty, then it's best to get a rebuilt kit that not only repairs wear but also uses parts that increase longevity so you can spend more time driving your Ford than working on it.

Better filter than OEM. Should replace it when you first get the vehicle.
Fits perfectly. Charcoal and paper filter is a huge upgrade from the factory filter.

Perfect fit, solved steering pump noise
Installed this o-ring kit on a 2009 Honda Odyssey. The steering pump was making noise and you could see bubbles in the fluid revivor when the engine was idling indicating a potential air leak from where the hoses attach to the pump. The most difficult part was finding the right 10mm wrench that would allow me to access the lower hose mounting bolt without removing the belt or pump pulley. I wound up taking an old wrench, heated it with a torch, and bent it in a vice to get the right fit. I did order a ratcheting, flex head wrench but while waiting for it to be delivered I was able to make something work. Overall, the o-ring kit worked great, the o-rings seem high quality and this fixed my issue. If you don't already have some, make sure to order the power steering fluid required for Asian/Honda vehicles when you order these o-rings.
