From a stop, if I do not creep very slowly into acceleration, the SH-AWD light comes on and all kinds of nasty sounds happen from pinging to clunking to grinding, depending on how aggressively I accelerate. Once I get moving (say 20-25 mph) it smooths out. So, as often as possible, I creep like Granny until I get to a speed where I can accelerate normally. Generally, I do not experience any issues at speeds over 30 mph. However, recently I’ve had it do the same thing mildly when I accelerated aggressively on the highway. The car has 180k miles and I’ve probably managed around this for about 10k hoping not to sink $000s in repairs. That said, I’m concerned about safety and feeling like I must be doing damage every time it does that.
One other thing. I had to the alternator replaced fairly recently and the mechanic said the SHAWD problem went away. Magically, he was right - for less than a week - then the problem came back. Thoughts? Solutions? Thanks!
The SH-AWD rear transfer case holds around 3 qts , has that been changed ever ?
Also , have you serviced the gear box on the transmission [ takes half Qt 75-90 gear oil ] ?

I have not done either. Historically I have left those kinds of services up to the suggestion of a mechanic. The mechanics (two) that I have used over the years have not suggested that. Something I can do myself? Thanks!
Can you jack up the RDX , do you have a half inch drive rachet and a pump ? If so it’s not that difficult, start with the fill plug before draining the rear , you don’t want to drain it if you cannot remove it .
After that remove drain plug and refill by a pump. The SH-AWD has clutches on both sides and to me it sounds like they’re not happy with the fluid or its level.
some replace the crush washer, some do not just so you know .
One more question: I ordered Acura All-Wheel Drive fluid for the front differential. The online picture shows no reference to 75w-85 or 80w-90. Now I’m paranoid I’ve ordered the wrong fluid. Picture below.
You ordered the correct fluid for the rear “differential “ . Three bottles ? The PTO on the transmission uses half Qt.of gear oil . The front differential as you called it is actually the transmission which use DW-1 .
you might consider finding another mechanic that’s up to date with Acura and Honda my man ..
