c6 downshift problem
new governor, new servo, new modulater new valve body. and the trans doesnt always drop down to first gear when you stop. give it more gas when taking off and it will drop down to first. the kickdown is hooked up and it will drop down if your riding along and need to kick it into passing gear.
so basicaly you stop start off again and it sometimes starts off in secound gear , anyone have any thoughts or suggestions on this?
the trans never slips and has clean fluid

If the engine idle is too high it can cause this or the governor is sticking.
Remove the extension housing.
The governor is held on with 4 small bolts.
There are 2 valves inside. The small one will be the culprit.
Sorry I did not see you had already replaced it.
But that is where the problem lies.

Your Linkage could be out of adjustment.When I had to remove my steering column I had to readjust the linkage at2-3 different points so it would shift into the proper gear.Do you have a Haynes repair manual or a chiltons it will help you adjust it out properly which my son did for me and my shifts like it should it was one of those little surprises I didn't know about with a C6
