Can I use a V8 A650E in a GS300?
Hello folks, quick question. I have two spare GS400 auto transmissions in storage (long story...). The A650E in my Turbo GS300 is dying. Can I use the GS400 transmission in the GS300? If I swap the bellhousings, what else is different? Torque converter, flex plate, input shaft, mount?
Thank you very much in advance,

I can tell you from experience the valve bodies have different calibrations. i'd imagine that the difference will help you in your situation since the v8 valve body is tuned for much more torque so perhaps youll experience firmer shifts but anything other than that is experimental. plus the 98-00 trans are different than 01-05 so make sure you use one that matches those ranges for your car. keep us posted as to what happens.

Thanks. I was not aware of the 2001-2005 differences. Any additional info on this? Maybe I could find out by looking at the electrical connectors? My main concern is flexplate/converter/input shaft compatibility.
Actually the gs300 has a higher torque converter stall speed and the rear diff. in the gs300 has 3.92 gear ratio. but I read the other day on tech. stuff that the gear ratios in the trans are the same. so if the flex plate is the same than count the splines on the input shaft and reuse the gs300 torque converter to avoid setting slip codes.
