Product Overview:

If you’re still running a stock C4 pan on your 1973–77 Bronco, you’re leaving performance on the table—and risking oil starvation when the going gets steep. The B&M Deep Sump C4 Transmission Pan doesn’t just add fluid—it’s engineered with off-road use in mind, including a proper filter drop so your transmission stays fed and functional in the rough stuff. Cooler temps, smoother performance, and better reliability—it’s the upgrade your automatic transmission needs to keep up with your Bronco’s capability.

Note: The dipstick location may interfere with some header configurations—re-routing may be required for best fit.

The extra capacity/cooling is good. The pan/dipstick don't leak at all compared to the stock pan that I could not get to seal without leaking. However, I it would be nice if there was more clearance around the bolt heads, and a better design for the dipstick tube. It required significant "modification" of the dipstick tube to clear the exhaust, will need to use one of the braided flexible dipsticks for a clean install.
