95 ta lt1 with lt4 hot cam over heats and shifting issue wont shift down to 1st
car started out as a v6 but i blew a headgasket and replaced with a lt1 and 4l60e trans had them both gone thru b4 installing it also had a pain free wiring harness and the computer is out of a 94 caprice classic water pump is working no air in coolant fans both working. seems to be a computer issue on the trans takes off the first time in 1st fine but will not down shift from second even if you try it manually it has a obd1 connector any ideas ive tried a different computer still same issues thinking its going into a limp mode but the car did have a 2nd gear start button where the traction control button on the v8s are does not matter if i press the button or not still wont take off in 1st gear after the first shift any ideas thanks
