Guys I have a c-4 that was originally a Lupo trans the good one they sell. It has been rebuilt many times by myself and as of late it is eating the clutches out on a regular basis. It is in a 3200# nos mustang that runs low 9s high 8s and I know something is wrong but cant figure it out. I have the right clearance in the clutch pack and it has 5 frictions. I have heard soomething about drilling holes in the drum to get the fluid out, would this help? How to go about this? I have also had some say that they got rid of the tbrake valve body and just went with a reverse manual and the clutch problems went away? It is a Lupo brake and whatever servos that came with it. Any help on this would be great. Thanks Damon................. PS I dont have the $ for a glide that I know I need.
