My original transmission is Opt F17 Code 5ASW 2.84 ratio. The regal I think is a W body w/ 3.06 ratio so it doesn't look like it will work. It's a shame that you cant tell the computer to "ignore" the slight ratio change..ugh!
Judging by the info at the website you linked the only transmission that ...

The guy texted me back and said the transmission came out of a 1995 Buick Regal LS (he probably meant GS) non supercharged.
Would it work if the ratio was the same as my Bonneville? how can I tell what ratio it is since it is missing the id tag?

thanks

Hi..thanks for the reply.
Unfortunately the tag is missing and the car it came from has been scrapped.

I texted the guy that owns the trans to see what vehicle it came out of. I haven't heard back yet..I do remember he said the year is a 1995..I'll update when I find out the make and model.

thanks

A acquaintance has a transmission that he said should work in my 1995 Bonneville, but it is missing the ID tag.

The only numbers on it he could find was 737 (on top), CFD 737 (on the side), and 24200287 hydramatic. I'm assuming these are all case/casting numbers and won't give me the info I need ...
