question : i took a tranny out of a 2000 bonneville , put it into my 2002 regal that wouldn't shift and fluid burnt . after swap the same problem exist ! the check engine light on , yet scan tool says no light and no codes ! was there any problems with the pcm'* in these cars ?
Not sure bout 00 Bonn but had 96 and it'* transm had vacuum solenoid on it, yet regals newer had one from97-04. If transm u put in regal have that vacuum solenoid then you'll have to connect it make it functional and I believe but not sure, re flash pcm
