350 turbo takes off in 2nd

What in the hell is going on here? I post a simple question and it end up with an argument between members about who knows what about governors.I have been trying for a year to get a simple answer or suggestion to my problem and this is what happens;I don't know who to believe. There has to be someone out there who knows enough about transmissions to give me a reasonable explanation without starting a war between members. So, once again my problem is that when my trans. is in drive it leaves in 2nd gear,bypassing 1st completely.If I shift it manually it works ok. I have checked the linkage,and readjusted it(both kickdown linkage and shift linkage),the vac modulator(even replacing it) checked all vac lines for leaks, the governor, and whatever else I could do externally. I pulled the pan and replaced the filter and checked all bolts and linkages,nothing hanging up,all moving freely. Please; someone help me out!

If you have checked all the listed items , all was fine as listed, then it is time to remove the valve body.

Check gaskets for correct orientation , check accumulator piston in valve body, check valves for free movement, check the springs for broken ones

Stan,let me throw this scenerio at ya. I got bit on this before. I'm checking the movement of the valve in the gov.when i depress the weights, to see that the valve moves up and down,and is seems ok, BUT,later I find out,it is NOT making it's full travel in the bore,giving me a mis-diagnosis that it's good.Sure enough,2nd gear starts are the result.You might want to look at it again.

I would also verify the modulator valve is free and moving the full stroke of the bore

If above checks out.
Intermediate clutch clearance may be too tight.
Was this a fresh build or old trans?
