• Q: How to Service the HYDRA-MATIC 4T80-E Automatic Transmission Filter and Scavenging Screens on 2000 Cadillac Eldorado?

  A: Service for the hydra-matic 4t80-e transmission filter must occur exclusively during transmission overhaul while replacement of the scavenging screens beneath the bottom pan occurs when changing transmission fluid. Your first step should be lifting the vehicle before placing a drain pan below the transmission bottom pan to collect dropping fluid. Draining transmission fluid becomes partial when performing the bottom pan removal since fluid remains in both the side cover and Torque Converter but you can extract more fluid from the side cover by uninstalling its Drain Plug following bottom pan removal. Drain the transmission fluid from the pan by loosing its bolts and removing the Drain Plug from the case. The next steps include bottom pan removal along with case bolts and seal before removing the screen scavenger on both sides. Disassemble the left and right scavenger screens when you need to replace the bottom pan seal because this component requires a brand-new replacement. The inspection of both transmission case scavenger screen lip seals requires evaluation for nicks or cuts while checking the bottom pan and transmission case for dents or nicks in their sealing surfaces and evaluating the bolts for damaged threads with replacement of faulty components. Bolt torque will remain correct when sealing surfaces of both bottom pan and case receive thorough cleaning before going dry. Start by fitting the transmission case Drain Plug followed by installing the new scavenger screens for left and right sides, then connect the bottom pan and new seal before lightly tightening the bolts. Reinstall the Drain Plug and new left and right scavenger screens on the bottom pan before hand-tightening the 16 bolts to 3 nm (27 inch lbs.) and to 6 nm (53 inch lbs.). Finish by tightening them to 12 nm (106 inch lbs.). The vehicle needs a fluid top-up with dexron-iii transmission fluid following the maintenance. After adding fluid users should reset both transmission adapts and the transmission oil life indicator.
