I just replaced the TBI 454 with a Caburated 350. What needs to be done to make this transmission (4L80E)shift properly?
All u need to do is get a holley electric choke carb model i think is 4150 or 4160 and get the tps sensor adapter for it it is around $110 and the carb is around $290 ur trans shifts off of the tps. all the other sensors are useless. i had that same problem with my 94 silverado.
That transmission is computer controlled the computer reads info from sensers on the engine with those sensers gone there are nothing to read so the computer does not know what to tell the tranny to do you may be find and computer setup from jegs or summit that will allow you to run that tranny with a carbed engine good luck.
