Not to be stupid, but have you checked the fluid level?? (truck running, in neutral with parking brake set) Makes me wonder since you said it worked better after warming up a little.

 

yes i have fluid is fine i am trying to figure if its somthing whith the tranny or the valve body or what else it might be

 

Yes, I understand that. I was workin on the "what else it might be" part. You always start with the basics.

 

check your TV cable isn't stuck- it can cause a whole host of problems.

 

Is your valvebody electronic? You might have to put in a resistor with an aftermarket valvebody due to the increase in the line pressure of the transmission. Mine did the 3-4 start but the restistor fix that problem. This may or may not apply as my truck is abit newer. Have you adjusted your kick down linkage?
