Downshifting an 18 Speed Transmission is a little more difficult than up shifting, as the driver needs to get the feel of the truck and speed and synchronization becomes more important. It’s an important skill that requires proper technique and lots of practice. We use the clutch when downshifting. It is easier on the truck, and it’s easier on the driver, particularly the new driver. If you use the clutch, then you won’t miss a shift, which is very important if you’re also using the downshift process to brake. No need either to use the foot brake…. can throw off the timing. Dave goes through the process and gives some tips for downshifting with ease.
