I recently put a used 1995 a340h in my 1995 4runner that has a 2003 3.4 liter in it. I’m getting a po773 code (shift solenoid E that the 1995 a340h doesn’t have). I have heard of people putting a t100 ecu in as they had a 3.4 with an a340h in their manufacturing years. Has anyone else heard of this? Any other suggestions besides valve body swap?
