Time to upgrade the transmission
It was rated for 400 foot pounds of torque( Factory stock motor is rated 400) 472 to the tires on the 1-2 shift.with the 16cm housing on the H1C turbo pushing 17psi .(took hafe way through 2nd gearr to max boost) Now I have a HX35W/ 12 hitting 20psi(stock fuel) now only takes ~ hafe way through 1st gear to max . That lasted about 2.5 weeks . The trans wet the bed. 2 days after the new to me turbo, I started hearing a planitary(i think) making a worbling noise very faint. Then 2 weeks later on the return leg of a test trip to Oklahoma city, OK from Greenville, Tx ~100 mi from the house it started grawling. 45mi later it stoped . A mpg query requires minimum of 100 mi (or 4ga witch ever comes last,eg 100mpg = 400mi test) in my book or it is just noise, not data.

47re/h 450TQ 94-2002 2.44:1
48re 570TQ 2003-2007 2.44:1
Both require sorcing a stock starter , tv cable,and adapror from the respective motor 96mph max
Allison
4 speed 545 drop in with spair parts from a 5.9 Cumins med. duity box van 3.55:1 finale

Both Allisons will need the US gear brownie reconfigured to Overdrive to be able to achieve what I am able accomplish with the Dodge trans.
All can be beefed up to over 1000HP ratingfor a extra cost rebuld.
