Add Transmission Tunnel in FWD Car
Introduction
A transmission tunnel is a structural component of a front-wheel drive (FWD) car that provides a passage for the driveshaft to connect the engine to the transmission. It is typically located in the center of the car, running from the firewall to the rear axle.
Adding a transmission tunnel to a FWD car can be a complex and time-consuming process, but it can also provide several benefits. These benefits include:
- Increased structural rigidity
- Improved handling and performance
- Reduced noise and vibration
Materials and Tools
The following materials and tools are required to add a transmission tunnel to a FWD car:
- Sheet metal
- Angle iron
- Welding equipment
- Grinder
- Drill
- Taps and dies
- Bolts and nuts
Step 1: Design the Transmission Tunnel
The first step is to design the transmission tunnel. This involves determining the location, size, and shape of the tunnel. The tunnel should be large enough to accommodate the driveshaft and any other components that need to pass through it. It should also be positioned in a way that minimizes interference with other components of the car.
Step 2: Cut the Sheet Metal
Once the transmission tunnel has been designed, the next step is to cut the sheet metal. This can be done with a grinder or a plasma cutter. The sheet metal should be cut to the shape and size of the tunnel.
Step 3: Form the Transmission Tunnel
Once the sheet metal has been cut, it needs to be formed into the shape of the tunnel. This can be done with a hammer and dolly or with a hydraulic press. The sheet metal should be formed so that it fits snugly against the floor of the car.
Step 4: Weld the Transmission Tunnel
Once the transmission tunnel has been formed, it needs to be welded into place. This can be done with a MIG welder or a TIG welder. The welds should be strong and durable to ensure that the transmission tunnel can withstand the forces that will be applied to it.
Step 5: Install the Driveshaft
Once the transmission tunnel has been welded into place, the driveshaft can be installed. The driveshaft should be connected to the transmission and to the differential. The driveshaft should be balanced to ensure that it operates smoothly and without vibration.
Step 6: Test the Transmission Tunnel
Once the transmission tunnel has been installed, it should be tested to ensure that it is functioning properly. The car should be driven under a variety of conditions to test the transmission tunnel’s strength and durability. The car should also be tested for noise and vibration to ensure that the transmission tunnel is not causing any problems.
Conclusion
Adding a transmission tunnel to a FWD car can be a complex and time-consuming process, but it can also provide several benefits. These benefits include increased structural rigidity, improved handling and performance, and reduced noise and vibration.
If you are considering adding a transmission tunnel to your FWD car, it is important to carefully consider the design and construction of the tunnel. It is also important to have the work performed by a qualified mechanic.
