Ford’s 4R70W automatic transmission traces its lineage back to the AOD (Automatic Overdrive) four-speed automatic introduced in 1980. Designed to improve fuel efficiency and reduce engine wear, the original AOD had durability issues, but the big problem was the throttle valve (TV) cable that connected to the throttle linkage to control shift points. That cable was finicky to adjust—If you didn’t get it just right, the transmission would eventually fail.

After 60 years of continuous production, there is plenty of myth, mystery, and misinformation about the Ford Mustang. Take the Mustang’s original 1964 production launch. While we know a lot about it, there are unanswered questions. Ford deleted production records at the end of each model year until record keeping became federally mandated in 1967 for all automakers.

Some background on the basic principles of gauge operation: Variable resistance to the flow of electricity to a negative ground (body/chassis) affects where the gauge needle moves on the instrument face. Electrical flow can be controlled by switches, resistors, diodes, fuses, and circuit breakers.

Every once in awhile, a really good idea comes along that just makes everything easier and better. The performance industry is slowly converting the old mechanical clutch linkage to hydraulics, but this most often requires mounting a clutch master cylinder on the firewall. While not a difficult process, it is imperative that the angle of the actuating rod from the clutch pedal to the master be as straight as possible.

It’s time for a new clutch, pressure plate, and flywheel in your 1960s-1970s muscle car and you’ve no doubt heard that it’s a good idea to also change the pilot bushing in the crank. Problem is, how do you remove the old pilot bushing out of the crank? Perhaps you’ve heard of the grease trick. This is where you pack the area behind the bushing with as much grease as you can cram into the area.
