Engines only work well within a certain RPM range. That’s why your truck’s engine’s output goes through a 7.3 Powerstroke transmission. If your truck has a 7.3 Powerstroke manual transmission, a clutch is used to connect and disconnect the gearbox from the engine. This consists of two friction plates that separate when the clutch pedal is depressed, allowing you to change gears more easily. +Read more
The clutch is also used to disconnect the engine from the gearbox when the vehicle is stopped, which prevents the engine from stalling. The plates then meet once the gear change is complete, sending power through the gearbox again. In an automatic truck, a 7.3 Powerstroke torque converter is used to connect the engine to the gears instead and serves a similar function.
Transmission rebuilds are pretty daunting, extremely technical, and often require an expert. Still, if you’re planning on tackling this job yourself, a 7.3 transmission rebuild kit will make the job easier. Even if a shop is handling the transmission rebuild for you, it still makes sense to buy a good quality 7.3 Powerstroke transmission rebuild kit. Some shops will charge a premium when sourcing parts themselves, and when buying your own rebuild kit you can be assured of the quality of the parts going into your refurbished gearbox.
Rebuilding a transmission tends to be cheaper than finding a new 7.3 Powerstroke transmission for sale, though there are some upsides to a complete replacement. Rebuilds tend to take time, while a good shop can fit a new transmission in a couple of days or a week at most. A new transmission will also last 200,000 miles, and will likely outlast the rest of the truck. Refurbishments may not be as long lasting, and can vary greatly in quality. If you want the absolute cheapest option, then you may be able to repair your transmission with the correct 7.3 liter Powerstroke transmission parts.
If you’re opting to replace the transmission entirely, then you may want to consider a 7.3 Powerstroke transmission upgrade. Upgrading the transmission may cost more, but it tends to result in better performance and fuel efficiency for your vehicle.
