Good products, may need to do some fitting.
I ordered 2 differential covers and a transmission pan for my 2004 F250. The transmission pan is nice and installed about as well as you can hope a pan to go. Keep in mind, it will not fit the FT-180 filter most other deep trans pans require for the 5r110. Must use FT-145 filter. The rear differential cover went on no problem. The front differential was not as easy. The drivers side of the cover interfered with the leaf spring mount to the axel, so I needed to remove about 1/4" of material, almost right to the counterbore face for the bolt. After this it fit perfectly. I used Lubelocker gaskets for both differentials, and a new metal cored rubber gasket for the trans pan and have had no leaks.

Dear Customer, Thank you for your detailed feedback. We are glad the transmission pan and rear differential cover worked out well for your 2004 F‑250, and that you have zero leaks after installation. We appreciate you pointing out the filter note for the transmission pan — FT‑145 filter is required instead of FT‑180. We also take your feedback on the front differential cover interference with the driver‑side leaf‑spring mount very seriously. We will forward this fitment comment to our engineering team for review. Thank you for sharing your real‑world installation experience. Please contact us if you have any further questions. Best regards, spelabautopart Customer Support Team [email protected]
