Your transmission fluid contain water,thats why the colour of the fluid changed to pink.And of such the clutch is slipping causing the engine to reve up before shifting - Check transmission cooler.

On the passenger side of the trans there are two servos.A servo is a steel piston with rubber lip seals bonded to the steel.The servo piston strokes in or out,applying or releasing a band.There are two servos,each hidden behind circular aluminum covers held into the case with snap rings.The rear servo actuates the 2nd gear band,and the front servo actuates the 4th gear,or O.D. band.The rubber lip seals on the servo pistons are soft and pliable when new,but with hot and cold cycles,and years of use,the rubber hardens and doesnt seal very well,causing loss of gears.It is very possible the servo has hardened,and that's why you are losing 4th.The other possible cause is electronic.This trans,the A4LD has 2 electrical solenoids inside the trans,4th gear solenoid and lockup solenoid.These are the ONLY electronics inside the trans,another possible problem area.I would remove the servos first for inspection,but before removal,take a scribe and scratch into the aluminum covers,"F" on the front one,and "R" on the rear one.These servos are different diameters,and MUST go back where they came out of.On the servo covers you will see cast into the covers 2 letters identifying the servo it requires....AB.....BB.....ZC...etc.These are examples,and yours will likely be AB and BB.If you DIY....use plenty of vaseline on the rubber lip seals,and the servo bores, to prevent cutting the new servo seals and O rings.Good luck.

I've read article after article on Chrysler forums where anything other than Autopar ATF in their transmissions cause problems, erratic shifting, etc, including what your experiencing. The techs that deal with it daily through Chrysler/Dodge shops, say there is some properties or chemicals in Autopar fluid, that others just don't have, no matter what they say, and they have proven it, time after time, with symptoms that disappear, just by changing fluids to Autopar. My wife's relatives own one of the more respected & trusted repair shops in our area, and they swear by that rule too, because they've also experienced it in the past. I'm naturally assuming you know that your experienced enough to know how to install filter properly & what to watch for, so with that said, I hate to say it, but Mopar ATF4 is the one & only fluid for best results. P.S. I recently had my transmission with 260,000km. replaced at Ontario Reman, whom back when I was with Chrysler, was the sole supplier of rebuilt engines & transmissions for Chrysler. When I questioned them on the fluid in my new/rebuild they responded with same answer, Mopar ATF and nothing else. If you do some googling on it, you'll find many that went to quick lube or similar for same service only to experience shifting problems etc after. Switched back to autopar as advised & problems went away. Can't say 100% that's your problem, but if it were me, I'd change it.

Solenoid pack in trans. Position module,is just that. Wrong guess. What tran model do you have? You also have other sensors to consider but have to know the trans your working on and the computer and shift stratagy involved to solve this,even if your throwing parts at it.
