It's about 75 F where I am, so I found that a bit surprising, but I think I know what's causing the rapid temp increase - I had to undo the downpipe-to-midpipe clamp to move the exhaust (I stripped the fill plug and needed more clearance to get it off, anyways...) which caused all that heat to dissipate near the transmission fluid pan instead of out through the back. I've reconnected the clamp so hoping that'll resolve my issue - will confirm when I get around to it.
Yeah I recall it took longer than the ista instructions suggested to get to the minimum temp for the fluid in both stages. I started the work with a totally cold car though (cooled overnight) and the instructions mentioned that it could take longer for temp to be reached if that were the case.
