I am in the process of rebuilding my 2.5 Lebaron. The engine is getting new forged pistons, ported exhaust manifold, new hybrid turbo, etc. I want to beef up the trany to handle the extra horse, 5 or 6 disc clutch pack, performance torque convertor, and some work on the valve body. I was wondering how difficult of a project this was. I've never messed with a transmission before. I read the a-413 upgrade sticky and he makes it SOUND easy. Are there any special tools needed? Any pointers or suggestions would be greatly appreciated.
