I recently changed my transmission fluid roughly 1500miles ago maybe less. I noticed some whining noise when I started up and got a little louder when running. Check on here and read possible cause was low fluid level in transmission. I unbolted fill bolt and it started leaking out like it should if its full. The fluid was black already is that normal for that few miles? And after I bolted back up I have not heard the whining noise yet . Any other possible explanations for noise?
I'm not sure on the color being black already; maybe you didn't get all of it out, which would explain the too full.. did you drain/fill on level ground?

So several fluid changes are required to get it all out then? And I took it to the shop when I had my clutch put in. Was told they flushed my trans too however when I got it home and unbolted it. It came rushing out like it was over filled with chocolate milk looking fluid so pretty sure they lied, didn't request that service but wasn't charged either... And I used Lucas 75w-90 all that I was able to get ahold of on short notice since I needed jeep back and running to get to work and school after I sunk it.
I have a 2000 sport TJ. I followed advice and instructions when i performed the fluid change from a thread i read on here however, i don't recall it mentioning changing the filter? for the trans. I just read about that when searching for threads with torque converter in it. The harshness of the gear lube is possible reason why i was hearing a whining noise? it stopped or is quite enough i don't notice it after i unbolted fill bolt the other day to check level. I used Lucas on my diffs as well suggest changing that as well? i can unbolt the fill bolt later and take a picture of the fluid if that will shed any light on what might be problem.
Only automatic transmissions have a filter & torque converter. Your manual transmission has neither of those. No need to change the Lucas out of the axles, they are fine with the type of GL5 gear lube you used in them.
