To anyone who has done valve body fixes or upgrades on a 10L80/90 IE sonnex zip kit 10L80-G1-10R80-ZIP or trans go SK® 10RL80-G1, which one would you go with and why? Also what would be the harm in using something in the sonnex kit that isn’t in the trans go kit or vice versa? I like that the transgo has a thermostatic bypass delete and that it comes with improved latch valves compared to the sonnex kit having to cut the factory ones and installing an insert and no bypass delete. But I like that the sonnex kit has end caps with O-rings where as the transgo kit reuses the factory end caps. Just as a couple examples. I’m just a little undecided on which one to go with, or do I use parts from both and get the best of both worlds?
