Hello, I have everything ready to drop the transmission oil pan and due to lack of time I have not been able to proceed. My Tj has 135k, I want to ask the experts here how do you see the color of the fluid in this transmission? I have no idea about the maintenance history. This apparent color has the liquid been changed before? or is it a normal color at 135k???

Chris, what would you do if you had it 3k Miles ago? Would you wait a little longer to change it or drop pan oil?
If you don't know the history, change it and start from there. Dropping the pan will give you a view you can't have looking at just the fluid.
If I didn't know the history I would change it just so I could stay on top of things and know for sure when I last did services.
As said above. If it is new to you, change every fluid in it so you know it is the right stuff.
I'll be the dissenting opinion here, I think that fluid looks quite orange. Clean fluid would be way more red than that, and typically dirty fluid gets more black-red or borderline purple. Agree with everyone else here, but for different reasons; change that fluid & filter.
I suppose, but it would be a strange reason, and would definitely warrant a flush. You know, or maybe it just wiped on your paper towel weird. Check it again, and take a picture of the fluid on the dipstick too. It's somewhat academic, since you need to flush it regardless. For kicks, drain some of the old fluid into a jar and then put some new fluid in another jar and post that here too. Maybe I'm just colorblind.
I also saw it orange now that you mention it Lol, I found this in a Google search. I hope to have time to make the change soon and compare.
The only time I've ever seen it orange is when somebody had a little too much fun in the TX/OK red dirt. But what do I know. I'd like to see a sample in a jar, and I'm always interested to see what's at the bottom of the pan.

I wouldn't be in a hurry to change it. Mixing coolant colors can be dangerous, due to their different chemistries. I would determine the proper coolant for your year Wrangler. Based on the proper coolant type, you can determine the proper color. Since you didn't mention the year of your TJ, it is impossible to determine the proper coolant or color. Mixing colors can gunk up your coolant system, ruining and clogging your heater core, water pump, radiator, and eventually your engine, because it can't properly cool. There are clear, red, orange, yellow and green. If you change it, you likely will just drain it, missing areas that don't regularly drain, causing coolant type mixing, which is bad. Just Google mixing coolant types and the problems especially common in TJ and JK Wranglers.
What coolant do you recomend for a 42RLE?
Dont want to gunk up the heater core or anything else
Hahaha, I did the coolant flush last month, we are talking about transmission oil sr.

I'm not sure , but for a GM Turbo hydromatic 400 I would suggest using a green IAT coolant .
