You..... just made my day.
I personally detest these fluid fill procedures that require exacting temperatures. It's such a scientific requirement that can't be replicated by normal people maintaining there cars.If you heat 6 quarts of ATF up to 150 degrees on the stove and measure the volume, and then bump it up to 200 degrees and remeasure.. the volume is prolly' within a 1% difference.
Regarding fluid level, the insides of a transmission is a very dynamic place. G loads from acceleration , braking, cornering and bumps has the fluid sloshing all over the place.
You should try to get the level spot on... but if you dont, I doubt its really a concern.
There is no "Hot Check" at the GM factory. They build the tranny, dump in the fluid.... and roll.
Mobil's DexVI is not synthetic, so that rules theirs out for me.Getting ready to perform this on my 2019 Premier with just over 20k miles. Ordered the magnetic drain plug 3 weeks ago via Amazon...short story, contacted the manufacture directly and the manufacture resent the drain plug last Friday and should receive the plug this week... I read through the thread and I have a question, I see Valvoline and Mobil 1 being the choice of ATF, has anyone used Castrol ATF? Reason why I'm asking, I still have GM change the oil free for the Traverse, ended up with a second booklet of free oil changes so no oil choice for the Traverse yet. But I've used Castrol Full Sync engine oil in my 09 v8 Colorado with 112K miles and have outstanding results and thought ATF might be as good for the Traverse? I also have a 99 modded SS Camaro and used nothing but Mobil 1 Full Sync, engine oil and ATF with outstanding results too. So...anyone have any thoughts on Castrol Full Sync ATF Dexron VI/Mercon LV?
I have been using Amalie full synth. Dex VI for a few years now in my GM fleet that's listed in my sig. line .Mobil's DexVI is not synthetic, so that rules theirs out for me.
Castrol definitely has it's fans. I have no evidence or empirical data to tell you why Valvoline is better than Castrol's DexVI but it's what I went with and what's easily available at the local WalMart so I will stick with it.
I know some on here have used the SuperTech DexVI and liked it as well. I believe it is full synthetic.
I've been hearing more about Amalie recently on the Pilot forum... no long term reviews yet though...I have been using Amalie full synth. Dex VI for a few years now in my GM fleet that's listed in my sig. line .
No issues and priced right with 2 day prime delivery.
Currently neither GM or Mobil1 have said that Dex HP is a suitable replacement for DexVI fluid. But if you feel like your transmission isn't improving with fresh DexVI it sounds like some have tried it with success.Has anyone confirmed that Dex HP is compatible with the 2018 9 speed? My wife’s traverse has noticeable shudder at low speeds
