I have a new G-Force G5R transmission that I started using this summer. I have found the tranny likes lots of RPMs when using the clutchless upshifting. I'm able to do that pretty good but I have issues when trying to do a clutchless downshift. The clutchless downshifting was one of the reasons why I went with a dogring tranny because I'm not very good at heel-toe (rolling the foot). I now use the clutch everytime when down shifting (still trying to figure out the rpm match). I do shift the gears very quickly and the engine is only a 10.6:1 compression ratio.

I've talked with the manufacture regarding the downshifting. Anyone who uses a dogring tranny shed some light on how they do a clutchless downshift ??
Thanks,
Brian

I drove my mates 64 Mustang at Daytona last year and he has a dog box in that and I didnt like downshifting clutchless, Ok going up through the gears but I found no advantage whatsover trying to do it coming down through the gears and baulked a couple of times trying so gave up on it. I can only see a speed advantage to be gained going up thriugh the gears in fact the owner of the car messed up his race tryng to downshift as the car got stuck in a gear and he had to stop briefly to sort it out, he also gave it a miss after that.
