THX heres how I downshift from 5th to 3rd push in clutch and while im moving shifter from thrid to 4th I hit the gas to where I htink the RPMs would be if I would just normally downshift. After i hit the gas an dget it in 4th I let off lcutch hit gas like normal. Downshift was very smooth then do the same from 4th to 3rd. now I have never went directly from5th to 3rd cause you would have to rev it alot higher I find it just as easy to go from 5 4 3. If you ask me the whole double clutch deal would take to long. theres no need to let the pedal out while in neutral to rev it upand yes stright cut gears like in alot older trucks do not use synchros and that is the only time you really need a true double clutch downshift but for our cars rev match works fine without damage
