Ok we put the sc on this weekend and now i have a code. It is a P0748 Pressure Control Solenoid code. What is that?? Is this making it shift hard? Help PLZ!!

 

Autozone can tell you exactly what it is.
Which S/C did you go with??? How was the install???

 

I put on a magnacharger and it wasn't to bad. I had a friend help and the book they gave was vegg but helpful. Ya it shifts hard now but i assume it is because of the pc.

 

Did you make any other mods to your truck at the same time? More Boost? Different tune?

 

Yes i put on the smaller pulley 7 psi. I did get another custom tune done (nelson) and 43# injectores.

 

HMMM, I would contact Allen. I am sure he will know what is going on.... How many miles are on the truck? Did you change the injectors?

 

Yes i changed the injectors. It has almost 53,000 on it right now.

 

It is possible that the pressure control solenoid is going / gone bad......Give Allen a call Monday, I am sure he will fix you right up! What was the reason for changeing the injectors?

 

I bought this kit and came with 32# and i wanted a little more because i heard of them running at like 120% duty when you boost them way up. It is a sidemount not radix. That is the only reason. Nelson is a great guy to work with and he has helped me a couple different times so i am going to the dealer tomorrow and seeing what they say. I thought it may of just wnet out but didn't know.

 

ahhhhhh, understood now! I will research that code more when I get too the shop tomorrow.
