I changed out my transmission fluid recently, and decided to take a sample for analysis. The sample was taken with the fluid warm and in mid-stream (neither at the beginning nor the end of the drain cycle).

The transmission whines in all gears except 5th. Now I'm wondering if there's more wrong. The car has never seen extended high-temp conditions (race track), nor has it ever been powershifted. Yes, it's been to the drag strip (<10 runs), but again, no power shifting, and all driveline components are stock, including wheels and tires, so there's nothing more than stock HP levels going through the transmission.

So, let me know what you think.

The synchros are copper, are they not?

switch to royal purple trans fluid drive it for a while and see if you get the same results...either way its covered under warranty...

If you haven't changed the MTF since new part of the possible issue might be from break in. Next test will tell you more as oil samples work best over time to show trends in wear.

Not so sure about warranty coverage, but I swapped in Redline MTL.

Maybe. I will sample again in 10,000 miles.

I suppose you haven't swapped to the thinner duel clutch fluid.

hawkeye18

Dual. It's DUAL clutch fluid.

And no, I swapped to fluid that actually works for the transmission.

There is a reason why Ford is using the thinner fluid. Experiment at your own risk.

I purchased the car at my own risk, since Ford runs from warranty claims like deadbeat dads run from child support payments.

I hold no faith that Ford knew, or knows what they're doing in regards to transmission fluid.

You have a point there lol.
