March 28, 2011Hopefully in the right place here, so here goes. I picked up a rebuilt 1989 tbi 350 with stock truck harness and 7747 computer which should be for a 700r4 trans. I`ve already installed the motor (with a modified carberated intake) in a 79 elcamino with a th350 transmission but ready for the tbi to growl. As I`m halfway through the harness conversion, I start to wonder... TCC and VSS sensors... If they aren`t hooked up, will the ECM still send correct signals (the Check engine light, I assume will burn a hole thru my face) or will I have drivability issues? Do I need to have it reprogrammed to a manual transmission?

April 11, 2011What can any one tell me about this part number 1227747 and where can i get a knew one?
April 11, 2011I may be wrong but from my knowledge they are in most 88 to 95 tbi chevy trucks. Mine was from an 89. I had found a website by googling it, then entered some more numbers ( off the sticker, I believe) it also told me it is for a 700r4 trans. As far as a new one, you won`t like the price if you can get one. I`d get one from a salvage yard and ask them what kind of warranty is on it if any.
Call me whatever you want, just don`t call me late for dinner.
