So I just injected 10oz of the friction modifier F and here are my thoughts/findings:
1. I actually injected it with the truck not running. The trans was at 140 F from running earlier today and the exhaust was just luke warm. When I loosened the dipstick cap I could hear the trans breaking vacuum or something and some fluid gurgling. But nothing ever came out or leaked. Fluid looked good too (granted I only have 20k). Do at your own risk of injecting when not running. Results may vary.
2. The friction modifier F is actually a very thick fluid. It took a bit of effort to inject 10 oz of it.
3. I have no idea how in the hell Ford injects it with the engine running. You literally have to hold the syringe tip in the trans dipstick hole with your hand pressed up against the cat piping and press down on the syringe with your thumb. Two hands are recommended to ensure the tip stays in the hole (insert crude jokes here haha). I tried from the side, but due to the thickness of the modifier it seems easiest to inject it from the top with the syringe vertical.
4. Driving/results - I started driving and the trans was at 140 F. I tried to make it squawk knowing it was too cool, and obviously got no noise. I did this every 10 F three times (yes, I was beating on it pretty good) and still had no squawking noise. I even ran the trans up to 206 F and still had no noise. This appears to have fixed the squawking noise for me.
Moral of story: don't waste your time at the "stealership" and just buy it for less than $50 shipped to your door and do it yourself. I mean sure that's $50 out of my own pocket, but the peace of mind of doing it myself, when I want, and how I want is worth it to me. Hope this helps you guys and best of luck.
