Not a J30 owner but...
I say put your money aside for now, and just let the car warm up. It could be something that is repairable, but people expect too much for a 10-20+ year old car to just lounge forward (or worse, backward) on a below freezing day.
I have to tell friends all the time: unless you’re in the summer in Arizona or Florida where it’s 100+ degrees, let your engine and transmission warm up for atleast until the temperature gauge starts moving...which can be from a minute upwards to 5 minutes in really cold climate. I have 2 cars with close to or over 300,000 miles on the transmission and engine, no rebuilds. Just a little preventative and proper cold starts....but I also don’t mind to push them to over 100 mph every once in awhile.
And someone told me, “I heard on the radio that modern cars don’t need to warm up”. Yeah, when they’re below 75,000 miles or it’s not below 32 degrees outside. Beyond that, it’s a good idea to.
That said: I would recommend a Vavoline or Castrol high mileage transmission fluid change. You can start with the drain and fill, then go with the drain/flush from cooler route later. I use those on my Nissan and Infiniti, and sometimes it can take a few hundred miles to start seeing the benefits of it. But not changing it isn’t going to save it any more than changing it.
I’ve never had a transmission go out after changing a fluid, and that’s been on cars from 96, 97 and 98. If changing it will make it go out, it’s not the new fluid that’s the cause (unless it gets under filled or overfilled in the process, which in my experience, even MECHANICS have under filled my fluids, hence why I do it myself personally). And unfortunately if fluid changes have been neglected or frequent improper warning up have occurred, I can’t guarantee it’ll “fix” it though.
