Continuation of Requested information
I bought a used low mileage Transmission. They sent me a U140E model. Previous one was U140 F. should I return it? Can I get a new U140F CONVERTER and replace into the U140E transmission. Is there a performance difference between the two transmissions or just the converter?

There is an upgrade you can do that is fitting a cooler in, Mine never had one from factory but does now. As far as performance goes you can make the car move but if you choose to drive it at its peak performance it be short lived.

I just found this:
"The U140E/F ("F" for F/awd) used in the RX300 from the "get-go" has a completely different transaxle control setup, solenoids, etc, plus the transaxle internal structure is quite different mechanically.
I guess he U140E was for the RX300s that were just FWD?
