I’ve been using Transynd for nearly 20 years and from day 1 on my Firebird and dragster combos so I can’t report on changes in flash with those combos. However when I went from type F to transynd in my turbo 400 with 8” converter in my footbrake launched Chevelle back in ‘05, the flash did not change but the trans fluid ran much cooler and I was no longer boiling it/shearing it/cooking it.
