Swapped the old trans on my old bonneville. Has 320,xxx. Yeah, well the new trans seems mechanically fine, got it form S&W so i have warranty. I also replaced the tourqe converter. Well now the transmission only has one gear that works. I have a obd II reader and it says shift solenoid a&b are not functioning. I unplugged the harness from the trans and it seems to only have 3rd gear and overdrive. I heard there is something with a valve or modualtor that hooks up to the intake or something but i cant figure out where. Anyone ever deal with anything like this?
