Will this C4 pan fit my bronco?

Finally getting around to replacing my leaking C4 pan. I happened to order the wrong pan at first, neglected to order one with a pickup tube for the dipstick. I'm looking at the following one from one of our vendors (link below), however it doesn't say it fits my bronco. I emailed the vendor, however I probably won't hear back until next week. So I thought I'd see what you guys on CB thought.

There's two pans, one black one chrome:

Chrome C4 pan

Black C4 pan

Can I place my order, or should I wait until the vendor gets back with me? :)

I'm pretty sure they will fit your Bronco but they are not as deep as a Bronco pan - Where is your pan leaking from? if it's the seal between the pan and the transmission you will be better off getting one of these - https://shop.broncograveyard.com/C4-Pan-Reinforcement/productinfo/11105/
this fixed my leaking C4 pan & it allowed me to keep the deeper original pan.

Thanks Bajabrewer, yes the pan is leaking around the rim/bolts. This looks like a great solution.

Just a heads up - I also got some bolts that were a little longer but you need to be careful some are thru bolts & a few are blind holes so you want to make sure the bolts don't bottom out in those. I also used some blue loctite on all the bolts.

You should also try to straighten the rim of the pan as much as you can with a hammer & dolly before you reassemble it

Good luck I hope it works as well for you as it did for me.

Okay will do, thanks for the tips. I was definitely gonna straighten the rim before reassembly. BTW, are there instructions with he pan reinforcement steel? That is, what order do they go? Rim, then steel, then gasket, then tranny?

The reinforcement goes between the bolt head and the pan to help distribute the load over a greater distance. I’m sure you’ll find bumps at every bolt hole on the gasket side. Make sure you hammer them back to flat so the gasket has the best chance for sealing. Also the longer you can wait before putting the pan back then putting oil in will help. Trannys drip for what seems like years and too much oil on the mating surface will prevent the gasket from sticking when it gets compressed. Same with waiting to get it wet. The longer it can be dry and stick the better. And when you’re tightening the pan bolts go over them multiple times. You’d be surprised how loose they can get once you get other bolts around it tightened.
