Thanks all, I appreciate the information. Considering I didn't top off with one liter after getting the correct amount of fluid spill from the inspection plug/level plug at operating temp, I topped off with 1L this morning. Admittedly, my 2019 ST has been driven about 30k Km's in this condition, and I didn't experience any shuddering, high temps, tranmsmission pump DTC's. Shifting has been smooth, perhaps due to the the PC being reprogrammed as per TSB 20-2190 at the beginning of this 30k Km interval. Just came back from a test drive after topping off with the extra liter, didn't feel anything different while engine was getting up to temp under regular load, or while driving while at operating temp. Maybe deceleration was a bit smoother than usual, but hard to tell since roads have been snow-covered for the past few days and are now cleared up. I will monitor over the next few trips, and will most likely do another drain/fill. will capture some pics of the fluid and post here as follow-up. Truly hoping that I didn't incur too much wear considering I had not topped off the 1L after obtaining the "correct" trans level plug as per the FSM's images from boosted's images above!

Hi BoostedEdge Thanks for sharing those FSMs. I have also done this procedure on my 2019 ST, and referred to the SM's you posted. The only procedure I did differently from the steps you posted is that I didn't top up the transmission fluid with 1L after filling with 6L then checking the level plug after reaching operating temperature since it seems that step is reserved for Initial Fills or for Transmissions that have been Overhauled. I didn't have mine overhauled or serviced, so I just did a simple drain/fill, filled with approx 6L, ran until operating temps were reached and checked the level through the level plug. In the attached references, it reads: 2022 ST FSM For Draining and Filling - Step 2. NOTICE: The following fluid amounts listed below are for initial fill only. 2019 Edge Transmission FSM - Filling Step 3. NOTE: Steps 3-8 apply if the transmission was overhauled. Did you have your transmission overhauled or a new one installed? I may be wrong so wanted to reach out. I monitored my temps on a long drive (2hrs) through some hilly terrain, max temps were 87C (188f), which seems to be similar to what you show here, so likely no overheating on either of our cases. But from what I understand, you don't want to overfill transmission units, nor do you want to be under by a liter.
