ATS Diesel 309-934-3224 4R100 Stage 3 Package 1999-2003 Ford 4Wd DieselThe factory Ford 4R100 suffers from weak points in the converter, clutch pack assemblies, valve body and line pressure limitations. These weaknesses arise when the motor? s power is increased or in towing applications. ATS addressed these concerns by re designing the torque converter, transmission pump, valve body and clutch packs. The result is a solid transmission setup to meet the demands of your Ford Super Duty. The ATS Stage 3 4R100 Features: ATS

The factory Ford 4R100 suffers from weak points in the converter, clutch pack assemblies, valve body and line pressure limitations. These weaknesses arise when the motor?s power is increased or in towing applications. ATS addressed these concerns by re-designing the torque converter, transmission pump, valve body and clutch packs. The result is a solid transmission setup to meet the demands of your Ford Super Duty. The ATS Stage 3 4R100

Features:

  • ATS Five Star Torque Converter featuring a billet cover, five lock-up clutches, billet stator and a furnace-brazed impeller
  • ATS Billet Input Shaft
  • ATS Co-Pilot Transmission Lock-up Controller
  • Modified transmission pump for increased line pressure
  • High performance clutch packs with more clutches than stock
  • Re-designed accumulator pistons for a precise shift feel

ATS Deep Transmission Pan that adds 5 quarts of fluid, featuring a finned design, magnetic drain plug and is tapped for a temperature probe. By increasing the line pressure, clutch pack surface area and modifying the valve body, the 4R100 becomes a consistent, responsive and dependable transmission.

The Stage 3 includes a billet 300M input shaft. As power increases over 400hp, or considerable weight will be towed, the input shaft takes the brunt of it. The ATS input shaft is designed to withstand extreme torque, converter lock-up sooner than stock, and competition and towing use. Beginning on the Stage 3, ATS includes a Co-Pilot Transmission Lock-up Controller.

This controller allows the user to lock the converter based on vehicle speed. The result is more power to the ground at a lower speed, thus improving acceleration, lowering transmission temperatures and helping fuel economy. The Co-Pilot will also synchronize torque converter lock-up with an exhaust brake, for added braking force.

The ATS Stage 3 4R100 is designed for trucks that see daily driving and heavy towing duties, aggressive tuning, and a modified turbo and/or injectors. ATS transmissions are backed by a 5 year / 500,000 mile warranty regardless of power level or use.

Just what my vehicle's A/C, heat system needed ..
Good fit, and quality. Easy to change. You might be surprised how changing the cabin air filter can improve the airflow in your vehicles A/C, and heat system.

Perfect fit, Easy install, Better than taking it to a dealer.
This filter fits perfectly and easily. Unlike the dealer-installed filter (which I assume was an OEM filter but maybe not), it has arrows that indicate which side and orientation should be facing outward. The dealer-installed one does not have this and, as you can see from the photo, it was installed incorrectly. It should not be folded in on the sides. The old filter in the photo is after about 20K miles if that is a useful reference for you. Also, if you watch any YouTube videos, you will see a reference to releasing a plunger as the first step in releasing the glovebox door. For my 2018 Honda Accord Touring, there was no plunger, and that was confusing to me. If you don't see one, just go to the next step -- squeezing in the top, back corners of the glove box to fold it down. After that, everything goes like in the videos. Getting back to this filter -- it seems like it's better quality than the dealer-installed one. Shipping was fast. I would buy it again but, because this only takes a couple of minutes, next time I would do both the cabin and engine air filter at the same time so you might save a little money buying the combo set. Again, a very easy install and you don't risk having a dealer doing it incorrectly.

Perfect fit
This fit perfectly into my cabin air filter slot. Save me a lot of money, getting it off here as the mechanics went to charge so much more money just to slip this filter into your car. Anyone can do it so don’t hesitate to do your own cabin filter exchange and save yourself big bucks.
