Late overdrive shifting and early TC lock
My 700r4 has been rebuilt about 3 times since i keep telling cottman that it isn't right. Now it will shift into all the gears but overdrive doesnt kick in until 55mph. once i reach about 43mph in 3rd gear (when my tranny used to go into overdrive) the torque converter will lock up which somewhat helps with milage but despite that something is wrong. It has a brand new Tv cable from gm and it has been adjusted. it did this before and after the new tv cable
I forgot it also will only downshift into 1st from second at around 21-22 mph or lower. It used to do it from around 34 or lower.
