Thread: P0243 and an intense shift pac????

I had the tranny scanned got a P0243,Boost cntrol circuit.I'm going to have it rebuilt soon and i don't drive the car that much now that i'm not working.So we put the shift pac in to see if it would help and it seems like it helped alot with the slipping into 1st, but now 2nd instead of shifting out at 86 at 5500 its like 95 at 6000 but only sometimes.It's done it 2 times really smooth the other time it didn't want to shift to 3rd so i just let out, and shifted fine until i got home.The car is pretty much stock. So any ideas. THANKS

From what it sounds like you may have either bad solinds for shifting or your clutchs in the trans are just wearing out.

Yeah, boost control solnid.I was worried that there might be problems with the ECU.
