700 r4 shift problems
I have a 83 s10 blazer with 2.8l and 700r4 trans I pulled the trans to replace seals. Now it wont shift out of first gear. So I jacked up the drive wheel and ran it up and it shifts out of first at 25mph and out of sec. at 50mph I have adjusted the t.v. cable the way it says to by releasing the tab and pulling the cable back and then pressing the gas pedal all the way to the floor. And then checking to make sure there is no slack in the t.v. cable at full throttle. since there is no adjustment on tv. cable other than setting this way. Im unsure of what to do to fix this problem . plus my trans shifted fine before pulling. any help would be greatly appreciated.
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
