Final drive ratios and MPG
Has anyone pulled down their a541e/a540e from a avalon or camry and taken note of what the tooth count of the counter gear ratio (under the o/d cover ).
I counted the teeth on my 04 avalon's "crown wheel" today ( thru the diff drain hole )and got 60 teeth,now 60t and 3.625 does not compute
NEW info found That shows that a 60T ring gear is matched with either a 14 or 15 tooth pinion
which either way gives 4:1+ ratio , and the same info also showed the counted gears as 2 sets in use in various models 1 being 2.7% under drive the other 5.7% overdrive.
So the info i now need from camry , avalon and solara people is which cars /years have a 58 tooth ring gear as this gear is matched to 1 of 3 possible pinions 15,16 & 17 teeth giving 3 final drive ratios 3.411 , 3.625 & 3,866 none which the australian 2004 avalon has in it HENCE why it's milage is RS.
AS you can see i need to change this 4:1 ratio to increase my mileage.
