Definitely can if proven you did not use Ford spec fluid. One of the dealers (Lebanon Ford for that matter - very good service department) warned me that putting non-spec trans fluid can lead to warranty claim denial is something goes wrong with trans (asked them to replace the fluid).
Scroll up a couple of posts.
It really depends on a lot of variables but it will last quite a bit longer than the OE fill. You may never have to change it until the next service interval. 50K-150K miles is just a little excessive IMO. Modern cars are High Power, run at elevated temps etc. Not a huge fan of extended drain intervals. The engine holds 8 qts gets changed every 10K at a minimum. The transmission only holds three qts, has all the power transmitted through it without the cooling the engine gets, no oil filter to remove debris etc.
But you asked a guy that sells oil :cheers:
I don't seem to find the code. I'd like to purchase the axle and tranny combo kit and would like the discount code also. Let me know and I'll make my purchase.

Curing the notchy-ness or gear nibble is likely more to due with the additives and their effect on how the syncros grab, allowing better shifting. In the first few pages of posts it was still cool in parts of the country and there was an improvement. The oil viscosity plays less of a role in the case of weather extremes. It is not a heavy oil used in modern transmissions, not like the dinosaur oil used in the old days that was like sludge when cold
Ask me next week, as you know from the other thread, I just made up the kits this weekend. I have attached the spec sheet which explains why BG developed Syncro Shift.
