• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Transmission Compatibility

I currently have a 2000 model Buick Regal GS with a 1998 model GS drive train. The trans is taking a dump after 3 years of being modded. I found a 2004 Monte Carlo SS trans with 27k miles for $200 with a guarantee and 30 day warranty. The numbers on the SS trans are 24220310. Would it work with my setup? Thanks in advance.
 


I don't think so. IIRC, 2003 is the last year that would work. (without internal modifications)

What are the letters/numbers on the ID tag of the donor trans?
 
2003 is a funky year, for ease..replace 03's with only 03's
04-08 is different enough that you can't easily put it into 97-02 cars.

You'd be best to stick to a 98-02 trans.
 
You can run an 03+ trans in your car if you replace your ECU with an 03 Regal GS ECU / Code.

Bill,

On my 99 Regal I had no issues. The BCM played nice, no issues with the passlock system as well. I drover that car for ~6 years with no problems, and sold it to a buddy that's still driving it.
