At the moment, I am rebuilding my 88´ TH700R4 tranny. I use a transgo reprogramming kit stage 2/3 automatic too. Now, I´ve a question.

I followed step by step in their installation guide. It says, i should install the white spring in the 2nd accumulator valve to have a "firmest shift". But this white spring is much more stronger like the original spring !!! Is this OK ???

The original spring is very soft and this white spring is very strong against the original one.... I hope, it´s ok...

Please help me....
