i will be doing this on a 96 es with atf+4-i want all the old stuff out. will do a pan drop and filter change and pump all out of torque converter with DIY method. have searched the threads and tried it on a604 minivan over a year ago. some questions and observations from other threads.
one user disconnected the cooler line at the TOP of the radiator to do this. in looking at the factory service manual. with the top outlet on the tranny being the return in line, and the bottom outlet on the tranny being the outflow line, the outflow (hot oil) line on my car goes to the TOP of the radiator. this would mean that this person was pumping out the from the tranny but never flushed through the radiator/cooler, no????? would this not leave about a quart of dirty fluid in that never got pumped out?
next, in looking at the factory service manual for procedure on "checking oil cooler flow" there is a procedure explained that sounds much like the DIY flush. it states to take of the RETURN line, route to a bucket, and run in neutral, and a quart should flow every 20 seconds-it states to never let go more than 1 quart low or internal damage may occur, fyi. but, it states to take off the return line at the TRANNY-not at the RADIATOR (or auxilliary factory cooler-mine has this). questions:
1. has anyone tried this by disconnecting at the tranny-it looks alot more accessible?
2. does anyone know the O.D. of the metal return line going to the tranny or the O.D. of the inlet nipple on the tranny?
3. i ask about the inlet nipple in number 2 above for one reason. when i did this on a minivan, as per allpar (and maybe i disconnected the wrong line), there was fluid flowing out the cooler line, which i had routed into a milk carton, AND flowing out the inlet nipple on the tranny-which i did not expect and it made a mess. anyone know why and has this happened to them on this car? could i safely plug the inlet nipple or does it have vaccum suction that could cause damage?
4. last, has anyone had to reset tcm or do relearn after changing fluid? on one minivan that dealer exchanged to atf+4, it started getting harsh shift down 4-3. he reset and did quick learn with drb and all better (that van, by the way went to 181K on original a604 tranny before sold in summer). this did not happen on other one i did myself-it was seamless.
thanks-sorry for babbling, i'm kinda anal about chrysler trannys.
