I had considered selling the entire box and transmission setup if the torque converter I am getting built doesn't end up doing what I want the car to do very well
(someone may want it for a different application, i.e drag)
But in all honesty, get the manual
If you would like to me expand on it, you should really, really, really get the manual.
To expand further, the gearbox has cost me closer to 10K to get it to where it is, which is good, but unless the TC from TCE makes it better than a manual (arguable!) you're at least, least, least spending 10K to get to the level where a $0 manual gearbox is at.
