I have been tracking threads all over and have been studying the feed back on the different solutions that have been tried.
I would love to get some additional feed back regarding fluid changes that worked and fluid changes that didn't.
Please give a little back ground as well, since driving a grinding trans for an extended period of time and then changing to a different fluid may not have an outstanding outcome if the blocker rings or synchros were hurt a bit before the fluid was eventually tried.
My understanding is that the factory fill is the full synthetic Ford, XT-M5-QS, 75W-90 gear oil.
The March TSB recommends using a slightly lighter Ford fluid.
For example here is a MT-82 owner who has switched to Royal Purple Max Gear 75W-90 and got good results. I would like to know if that was the only fluid that he has tried or were there others.
He suggests not using the Synchromax but I don't know if he tried it or not, so I am wondering what was the outcome of those who did try the Synchromax or any other fluids.
I have followed this thread and have heard about some shift issues being clutch related as well.

If you or your Ford dealer/repair shop has tried something, what was it and how did it work?

I understand what you are saying however the TSB advised to use DCT fluid in place of QS.

The DCT fluid is a 75w-90 gear oil based on my research. Based on my experience using the RP 75w-90 gear oil, my trans shifts better then when new and I run the piss out of my car.
I would not recommend using Synchromax however.
