I bought a couple 5 gallon pails of it a few years back for $135 a pail VS $160 for TRANSYND. I will say TRANSYND is the coolest running fluid I have ever seen. I ran TRANSYND with my stock cooler and never had temp problems, switched to DEX/MERC fluid and the temps ran a good 35-45 degrees warmer with the stock cooler, swapped to a bigger cooler and brought them back down, swapped to QUATRASYN and dropped down 10-20 degrees, and when I had to go in it last time for the torn C4 piston I put TRANSYND back in because I had it and my temps are down a good 20 degrees VS QUATRASYN(but it just doesn't shift as good as QUATRASYN did).
