The 05-06 SSR's computers dont like the 4.56 gears. The ECM and TCM will take the change no problem (I can log the speed in my scanner against a GPS and it will be perfect) but the BCM that controls the Speedometer will not take the change. I have gotten a few close but never perfect and get at least 1-5 calls a week on this subject. I know of many that have gone back and reinstalled 4.10 gears after a while because the speedometer is so far off.
