Frankentranny revisited

[4x4player]

I love the the fact that Brian and Glacier put so much effort into the A4LD projects.
After reading the Frankentranny project I am wondering if the A4LD remained a 4 speed or was it made into a 5 speed?
Would it be of any benefit to use the early 1985 single solenoid tranny to do a Frankentranny when using an aftermarket EFI?
Also, somewhere I read an article (not here) about using the TCC for a poorman's gear splitter using a switch. Anybody know about this?

Welcome to this forum! It's a 4 speed. The TCC only engages & disengages the torque converter. The gear shifts are hydraulic except for overdrive which is computer controlled by the 3-4 shift solenoid.
