Ford Lincoln Mercury 4R70W Transmission Service Manual (OEM) Group 7 of 17

This is the 4R70W Transmission/transaxle chapter from the official (OEM) Helms (Ford Motor Company) 1997 Mercury Cougar Service Manual scanned and OCR (searchable text CTRL+F.) Do you or someone you know have a Ford, Lincoln, or Mercury with a 4R70W transmission and looking to rebuild/overhaul or simply want to drop the pan and valve body to do a J-mod for firmer shifts? Maybe it has over 200,000 miles and the engine revs but doesn't go anywhere? Don't pay someone else to do it! I've never rebuilt an automatic transmission in my life but after reading this step-by-step tutorial with the assistance of the forklift mast weight "I didn't want to pay someone to use their hydraulic press or rent one" I had it back up in running for $250 for the rebuild kit and another $250 for a torque converter. Most automotive service manuals are written by Helms available at www.helminc.com Attention: One tip you must know if you don't already, SOAK ALL CLUTCHES IN MERCON V! If you do not, you will be at square 0 because all that paper clutch material will get hot and shear off the first time a clutch pack engages. Cleanliness is next to godliness ;) If you have never done this before, label everything step 1, step 2, step 3 according to step number in the manual for reference later. Get yourself some ziplock baggies, plastic wrap all subassemblies together until ready to rebuild them one at a time and work backwards on reassembly. You don't want to play the guessing game!
