Tranny down shift problems.

[Jason Roberts]

Hey guys I was just wondering if any one could tell me whats up with my 350 tubo.
It goes through all the gears fine but it will not down **** when i slow to 35,It will only down shift if I slow to under 20It is becoming a real pain in the ass espesially on on ramps I have to manually shift it down to second.
I changed the govener from another tranny but all that did was change the shift points any help would be greatly apreciated.
