It wasnt your regular shiftkit mod that adjusts the s5 solonoid. It was more hardcore and it bypassed the solonoid completely.
It was harsh as but my trans overheated without it.
I think eaturbo posted the diagram on one of the old fordforums (can somebody search for it for me pleeeeeaaaaasssse). Turbotrana uses it as well. It might be in one of this threads.
Does anyone have the diagram? I know I sent it to a few people but Ive lost it.

Thanks.
Dan
