I havent seen any powershifts in the few pulls I help with.Even though we have JDs the Red ones are hard to beat especially if you are trying to keep the cost down.Big JD H.P.is expensive.I know a guy that made some over a million dollars pulling that started with around two.Just Kidding.   [Reply]  [No Email]

Seventh gear should be fine, but remember you are shifting 3 clutch/brake packs at the same time,which gives the "delay". If you are way up in the HP department the input shaft will likely become the "shear pin"   [Reply]  [No Email]
