Non Bronco C4 installed

[ngsd]

I picked up a Bronco that had a C4 in it that looks like a Mustang C4. It fit the same but looks different. Is this a common sap and if so why aren't more of these used? Is there a downside to them? Just curious

Is it a cast fill? That is the dipstick tube is O-ring sealed to the case instead of threaded into the transmission pan?

Ford built several versions of the C4 over the years. Used in everything from pintos to fairly large cars, vans, and pickups. With such a wide range of applications there are plenty of different levels of build. The mustang was considered a small car, didn't need a heavy duty version of the transmission. The case fill housing isn't as strong, but strong enough. The Bronco is probably the most severe service the C4 was ever installed in from Ford. They put the best parts they had into it. The strongest case that was also used in the big cars. The best servos. And for good reason. The transfer case, in low range, creates a lot of torque. That torque multiplication is carried through the transmission into the engine block. Even if the engine isn't that powerful, there is a lot of gearing that can make a lot of torque. The double transmission mounts do help a little, but still the transmission case takes a lot of the brunt.

Will a mustang C4 work? Yes, and for the most part it will work just fine. Drive it normal, with the right axle gearing for the size tire, it isn't an issue. Drive it like it was a farm truck and you are only a worker on the farm and not the owner of the farm, probably isn't going to last very long.

It was behind a high hp 408 but I don't have any info on it and whether it was built to match the engine power.

Don't have the angle I typically use to tell what version that is. But I see a flare in the case at the bellhousing. I am pretty sure that is enough to call it a Bronco C4, or at least one of the better C4 cases.

I hope they were running more cooler than what you are showing.

its not an original Bronco Case. it could have anything built inside it all the good parts still fit inside the passengers case. does it have the Bronco hump pan and was the case made after 1969 in 1970 the valve body changed and required a redesigned case. cant put the newer valve body in an older case.

What servo does it have in it?

Here are a couple more pics if that helps ID it

The good news is it's 1970 or later (stronger input shaft). Bad news is it's case fill (weaker case and bell).

Yes it gets me wondering. It was behind this engine already and not used hard off road so may be fine. Also considering a 6r80 but the costs makes me consider what I have may just be fine.
