Think I remember seeing a post about it. Probably by you. Billet piece that replaced the rear seal/bearing retainer. ORD can modify rear housing as well to accept a VSS sensor. As you most likely know the 6L80/90 use a front and rear VSS to control shifting. The reluctor wheel included in both of those kits has significantly less teeth than the rear reluctor in my 6L90. Assuming the wheel generates pulses, I made the assumption that those options would not solve the problem and probably create more. Still do not have enough information to know if anything can be changed in programming to change the value of pulses at rear VSS.
