Not yet, but I've been using my IR thermometer pointed at the trans pan. Before the mod on a hot day, it read 218 degrees. This morning, not as hot outside as before I did the mod, but it read a cool 161 degrees after the drive into work (about 20 miles, some highway driving).
I wanted to put a gauge in while doing all this, but none of the shops in my area have electronic gauges...just mechanical. I'm not too keen on running a tube of tranny fluid to my interior. At least I think that's how they work. I will likely order one later this week.

^ From what I have read, mechanical gauges no longer use caustic fluid in the tube. It is now non-toxic. The trick is getting a gauge with tube long enough to reach.
I have an electric sender in the hot/out line and mechanical in port on AW4 (1999 and earlier AW4 have a threaded sender port which Toyata used. Chrysler never used it). You may want to plumb in the stock cooler, after the aux, for your PA winters.
B&M Racing tranny coolers have built in flow restriction until fluid warms up.

I had a mechanical auto meter oil pressure in my car. The copper line they provide works ok but it snapped one day and my engine caught fire a bit. I recommend getting a braided stainless line for it much stronger and safer.

Got the better MC/Booster out of my parts jeep, also took the steering shaft off to swap that out on my 91.
Got the MC/booster off my 91 and that's when I had to quit for the day.
