I'm changing out the rear wheel bearing and seals. got one bad on left side, so I'm going to change out both sides while into the differential. My question, thinking it's going to take 75/140 full synthic fluid, not knowing whether I have the limited shift rear end or not. Should I still should use the additive for the limited shift? What brand of 75/140 is the best brand to use? ]]> Kybill1252 https://www.ford-trucks.com/forums/1805453-differential-fluid-and-additive.html https://www.ford-trucks.com/forums/1805363-c6-shift-points-new-post.html Sun, 07 Jun 2026 14:53:00 GMT What would be the optimum shift points for my set up? 460 with 3:73, P255/70SR15 tires, I have adjusted the modulator but it still seems to shift early. It's actually hard to tell when it shifts, I'll have to pay attention to the tach. ]]> 55F250 https://www.ford-trucks.com/forums/1805363-c6-shift-points.html https://www.ford-trucks.com/forums/1804912-4r75e-parking-pawl-replacement-new-post.html Wed, 27 May 2026 00:48:02 GMT Today I was changing the parking brake shoes on my van, and to test the brakes I had the rear end up on jack stands.

Today I was changing the parking brake shoes on my van, and to test the brakes I had the rear end up on jack stands. The calipers were still removed, with only the rotors installed so I could check for clearance/rubbing and adjust the starnuts as needed.

Unfortunately, I accidentally shifted from Park to Drive, set the parking brake to test it, then released it and moved back from Drive to Park without the brakes applied while the axle was still spinning. The rear axle kept spinning in Park, so I suspect the parking pawl may be damaged. Although not a good thing for sure, I am surprised that a parking pawl would break with the axle up on jack stand and no weight on it.

Can the parking pawl on a 4R75E be replaced just by removing the pan, or is it a much bigger job? I’m hoping this is something I can fix without spending several thousand dollars.

Thanks.
