The Allison is doing great.I have been doing alot of tuning was making progress
but had very harsh 4 to 3 closed throttle downshifts just couldn't get it right.A couple of the EFI live experts would just it's in my tuning.I offered to pay them for one of their tunes never heard back.So I came across with a Medium Duty calibration no.for a 6sp.My buddy had a tcm programed with this cal.no.work great in his dodge.Took his tcm put it in my truck.My trans acted the exact same way.In the way of deduction next step was the valve body.My buddy had a stock one that he test the 6sp.with.Took mine out and put his in.Very much to my surprise the trans shifted just like a new Duramax I was happy as hell.We took my vb.apart found the A.pressure valve the ball had fell out when the shift kit was installed.The ball was in the cavity bouncing around.Reinstalled it back in my trans shift alittle firmer than the stock one.I would recommend the Allison for a trans swap to everyone.Well worth it.
Tap shift working great.I have my drive mode the tqc locking up 4 mph after 2 gearshift and staying locked through 6th.Have to work on TowHaul now that it shift great.In my down shifts is smoothly holding the truck back.Very good slowing down with the exhaust brake.
Will keep everyone informed.
Making the inner fenders for the front they have to stay mounted to the frame.
They will seal when the clip is in the down position.
will try to post some pic.
