As promised, The good, the bad and the ugly
Whomever came up with the bastardization of this transmission installation in the Rams should be hung from their cajones in the middle of the Mohave desert in July.
All of the nonsense could have been avoided by moving the flipping fill hole to a higher location and OMG maybe one for cold fills after a service? NAHH that would cost almost as much as a dipstick, dipsh-t.
The Ugly: having not done this before I was unaware of the intensity of the circle jerk involved with verifying the level once filled.
I was also unaware that one should likely start the verification at the low end of the temp range as by the time one is done burning the skin off their hand and arms they will be outside the high end temperature. The placement of that fill hole and exhaust was obviously intentional by some sadistic SOB that daddy should have flushed down the toilet.
By this point you are likely aware that I thoroughly enjoyed my experience today.
So lets move onto the bad:
While getting the fluid in the trans was a breeze, removing the modified fill plug with the 90 degree elbow and hot exhaust was anything but fun. I should mention the install was easy as I used a 1/8 NPT M x F 90 and then a 1/8 NPT to hose barb and the exhaust was cold. PROBLEM: When trying to remove the assembly the hose barb interfered with a harness or something. OK reverse the installation with hot fluid and exhaust while the engine is running and the trans temp is doing what ????
I do not think anyone that is reasonably sane could have come up with a more idiotic process.
let's not forget the butt end being up 9 inches off the ground and 5 seconds in R N D followed by 5 seconds at 2000 RPM in second gear.
THIS INDIVIDUAL WAS DERANGED.
OK remove the modified plug and lose X amount of fluid as D AZ me shut the motor off while doing so. but was smart enough to install the factory while waiting for it to cool back down to the low end of the temp range for verifying the level.
Refill sprayer bottle.
Once cooled, loosen plug almost all the way.
Start motor
The Good: The bottle with the hose by itself (no fittings or modified plug worked quite well at replacing the lost fluid. took almost 2 quarts which surprised me as I did not think I had lost that much.
I may recheck at the lower end of the temp range as the fluid does expand when hot. So it may be a bit low when cold. I would rather have a bit more than a bit less

I will look tomorrow to see if a straight hose barb will clear the exhaust as that would have simplified things but then I wouldn't have had as much fun.
I'm not sure you can comprehend what I might do the the individuals involved with this design if I were able to.
But then again at the time they were owned by who?? Fix-It-Again-Tony. I can think of several meanings for FCA none of which have anything related to Chrysler.
Walter P must have been rolling in his grave
