02 Deville transmission swap

Recommended Posts

I have an 02 Deville DTS vin 9 and I need a new trans. Can I install a vin Y trans, if yes, will it work properly with the vin 9 computer?

No its a different final drive ratio, the PCM will have problems with it. Do a search under member name Dana and transmission, he recently had the problem of a shop installing the WRONG transmission TWICE!

And NO you can not change the PCM, the two platforms have different CAM shafts also.
