I would appreciate it if you would put up a list of any upgraded internal parts that you sell for the 4r100. Im considering rebuilding and upgrading it myself and would like to just get some ideas.

I probably didnt pay enough attention looking through your older rebuild of a e40d, but do the planetary gears use flat roller bearings?

The last thing id like to add is that with my current modifications that put me around 350 rear wheel hp, the shifts are not good at all. The truck is a 2002 7.3 diesel. The main problem shifts are from one to two and from two to three. They feel like they go into neutral then grab hard and bang at acceleration over 2000 rpm. I would just like to make sure you specify what will be required mechanically to solve that problem.

Thanks
