shift solenoid wiring help
Wednesday, March 07, 2012 7:35 PM

I am putting a 3800 into a sunfire and the solenoid shift pattern is backwards on the sunfire trans.
It will shift 4-3-2-1 instead of 1-2-3-4.....how do I change this?

I just noticed that the A solenoid is run the same on both transmissions but the B solenoid is backwards.
If I put a PNP transistor in the B wire it should work right because it would do the exact opposite of what it is told and would therefore be doing the right thing.
Does this sound right?
