Linus,
The big difference between what I did and what a dealer or lube place does is that I didn't use a closed-system forced flush.....which is what apparently stirs up all the junk and causes more problems on older transmissions. After draining, dropping and cleaning/refilling the pan (5 quarts), I did a flush where I let the vehicle's transmission cooler-pump - pump out fluid...I captured a specific volume (3 quarts) at a time after the second trans cooler and then refilled the same volume. I repeated this last step 3 times and then followed the FSM to ensure the trans temp was at the correct temp to measure the fluid level. I went through 14 quarts of fluid and it is red red red now!
I had 103K miles on my LC. I have some photos and a video that I need to compile/edit that'll show it all. I don't tow with this (I have a Cummins powered Ram Mega-Cab for that)....and from the fact that my LC was missing the towing electrical harness - I'm guessing the prior owner didn't either.
NLscooby where exactly did you disconnect the line and which one is it behind the front grille like on a 80 series
Or is it somewhere else on a 200 series? I've done this method on my 80 by just disconnecting one of the lines from the transcooler start the rig up let it pump out 2-3 quarts then turn off replace what came out repeated process until fluid was nice and red.
It was mentioned on a different thread that the 200 series has a thermostat somewhere in the transcooler? Did you
Do the pump out 3 quarts fill 3 quarts while fluid was hot?
Could you point out which line you disconnected when you post those pictures/videos.Thanks!
