This is why I like doing my own work. Obviously it's just not possible for all of us, but when you go to a mechanic it's always good to ask for before and after pictures. I also do that for alignments to see the difference and see if they actually did anything (not scamming me for money) and see...
How many miles have you put on it since the full fluid flush? Also, transmissions are very sensitive to fluid level. Was the level checked to make sure it's at the proper quantity? Who did the transmission service, was it you or a shop, did you get to see the before and after of the fluid?
It took me about 100 miles worth of driving for it to stop shuttering. The more miles I put on it the better it got. The new fluid is literally cleaning sludge/deposits/crap whatever you want to call it off of the internal parts of the transmission and depending on how "dirty" your internals are...
I had a crazy amount of issues with my transmission when I first got ownership of it. It would hang up and rev high-ish in 4th and then shake while in D. All I did was a full 12 qt+ fluid change and after about 100 miles-ish it was driving like new. You better get some money back for that...
What Would Be The Most Reliable Tallest Setup
So I have 2009 Limited V6 4x4 with XREAS. My main goal is to lift it as tall as I can go without a body mount chop, and I think that’s 3.5 inches suspension lift (changing the brake lines to stainless steel and making them longer) and a 1 inch body...
If you go to post #280 you can see why I didn't bother getting an analysis done. If they were free, sure I would have sent a sample to the lab just for the knowledge. Check out the link below and read every post and every reference in that forum if you want to learn why the WS fluid is bad...
My proof is my own transmission and real life testing, but I'm just a mechanic, not mechanical engineer. I still say the fluid is junk because I have a 1997 F350 with 245k towing a 31ft trailer its whole life and the transmission fluid is still good. That fluid was tested by an oil analysis...
I'm not really sure the number but there were some other guys in previous posts of this thread that were referenced. These guys are crazy smart, they're hydraulic engineers that work with hydraulics daily. Anyway they said that this WS fluid is garbage. It's good for low temps in the winter for...
Flush All Your Fluid
I would first start with doing a full transmission fluid flush, make sure you get all of the old bad transmission fluid out of the transmission. You cant just put 2 oz of additive into completely shot fluid which at full capacity of the transmission is 102.4 oz and expect...
When you say serviced, what does that entail? I did a 12 quart flush all at once, after the new Castrol ATF got a chance to wash all the clutch packs inside, everything is now working like new. This should have been the same for you. If you look at my previous post you'll see that my fluid was...
So update on my transmission flush. I have 1200 miles on the new fluid. I only did a flush of 12 quarts and the shaking is completely gone.

Adding Shudder Fixx
Thanks!:iagree: I will be adding it with the new fluid at 5,000 miles. I wanted to give the new ATF a chance to wash everything, and then I'll add the Shudder Fixx with the AMSOIL. I must say with every mile I put on the new fluid the shudder gets less and less. I feel like...
Just changed my rear differential oil this weekend. It had 150,000 miles on it, it was black, smelled burnt, and there was metal on the drain plug. I filled it back up with AMSOIL 75W-90 using a hand pump made by AMSOIL. That pump makes your life so easy. Changing the rear differential oil has...
More Than Overdue
So I finally got around to changing my transmission fluid on 04/21/2018 with 150,000 miles on it. I only went through the cooler lines due to the transmission pan having a good amount of rust built up on it around half of the bolts. I didn't have a new pan at the time so I...
