Pratt Automotive. It’s right at the SW 820 in Benbrook. It’s right where SW 820 and I20 meet. It got bought about two years ago but so far they’ve been just as good as the original owners.

Toyotas have a drain plug, a check plug, and a fill plug. You fill, warm the fluid to 110 - 130 degrees and pull the test plug. I will measure what I take out and add a few ounces more. Normally just get a trickle out of the test plug. Transfer case on a Tundra takes 75w now. They are finicky and if you use 75w-90 they will not shift correctly. They are a simple drain and fill. I changed the tcase fluid on my Tacoma and will never bother with it again. After 50k it was clean. I attribute that to the time spend in 4wd.

I have a 2014 Toyota with 50k miles on it. I took it to the dealer to specifically get the transmission fluid either changed (pan drop) or a flush. Basically whatever they recommended. Because yes I too have heard all the bad things about a flush. But they told me I'm good till at least 100k and they said a flush is better for more modern transmissions. The vanster was a Kia and I had the transmission flushed at Jiffy Lube at 100k miles. Never had any issues after putting another 80k miles on it. It still runs fine, I just don't drive it anymore.

This is the correct answer ^^^^.

I talked to the Service Manager and he said they recommend drain and fill at 100,000 miles so it should not be a problem.

He did mention the rear differential oil should be changed every 35,000 miles according to the maintenance schedule.
