The purpose of this article is to explain and cover some basic info about do it yourself C-4 Valve body service. The actual valve body is from a 1974 Bronco, therefore the illustrations may differ slightly from what you may be working on.  If you are inexperienced as a mechanic, perhaps you should get help when performing the steps shown below.

Since I’ve owned my 1966 Bronco it never got past 3rd gear for years and I drive the freeways in Los Angeles all the time.

Finally I collected the parts to install my new NV3550 and a twin-stick shifter I purchased made for an early Bronco.

The problem simply was the twin-stick shifter wasn’t designed with the offset of a NV3550 in mind. With the mounting bracket of the twin-sticks, the bracket supplied by Advanced Adapters, and the height of the shifters I could see it wouldn’t work.

This write-up summarizes how I put on-board air into my 1971 Bronco. I have a 3.5” suspension lift, a 2” body lift, and enjoy wheeling. Having on-board air is not only a nice benefit to airing up and down tires but could also come in handy for a variety of other uses (i.e. any air tools, nail guns etc.) Deciding on the proper system for your application is always the hardest part. I searched the internet and found all kinds of articles on how to do it – except for the installation on an early Bronco.

While gathering parts for my 5.0 EFI install I happened across a two speed electric fan from a 2004 Jeep Liberty, part number 55037669AE. This Liberty did not have the towing package. With the towing package the Liberty will have a different electric and a mechanical fan. The shape looked simple enough to make fitment easy and the depth was only about 4 ½” which was as short as I have seen any others. Read the rest of this article »

Many modern vehicles with trailer towing capability have dealer or aftermarket support for trailer harnesses that simply plug in to the vehicle’s factory wiring harness. Early Broncos do not. However the factory Bronco harness has the advantage of simplicity of design. After examining the taillight harness it became clear that a plug-in trailer harness would be a piece of cake to build.

This is the second article in a two part series on popular transmission swaps into your early Bronco. The first article focused on several manual choices for those who like to row their own gears. This second article is for you folks who prefer the ease and drivability of an automatic.The 3 speed manual or C4 automatic that came stock in the Bronco serve their purpose, but they’re not the best to be had. Some people want a stronger, more reliable transmission with ultra low gearing for those tough trails. For others, street performance is more important and a highway friendly overdrive becomes essential for those long commutes. And then there are some (all?) of us that want both!
