I has a BRAND NEW GM trans for sale - 2004 Model year Regal GS. This has the same plug as the 2003 Regals. I think the only difference is the torque converter stall speed. So, from all the research I have done, it seems to me that this will work in a 2003 GS with the 2003 converter.
Located in south eastern PA near Delaware and MD lines
I can ship it, but it will need to go truck freight.
