As far as I can tell there are 3 companies producing converted 48RE valve bodies. The Sonnax unit is around $900 US for it's patented design. One I will not mention as it is priced out of range for most anyway.The one I have decided to go with is Central Valve Body Billet 48RE conversion kit & all available SONNAX 47/48RE updates in my hybrid 47/48RE build so my review on this is a few weeks away now.

More images and just found out TransGo will be releasing a total tune kit for the 47/48 hybrids soon. The pressure sensor w/white cover is the HP 200 psi unit.

Here we are one year later and I had a 48re only failure, that confused everyone especially me.

Torque converter locked "always" is limited to the 48re trans period, which caused the truck to stall when placed in gear. The culprit was TCC solenoid failure. Changed out the solenoids and fixed the problem.
