AOD vs FMX
I want to change my '34 sedans FMX transmission to an AOD. Is the AOD larger in diameter than the FMX?

Re: AOD vs FMX
On the AOD, pay close attention to the rear end gear ratio. With a 3:70 or lower, the 1-2-3 shift occurrs way too soon and downshift not soon enough causing engine bog. I used a Transgo Hi Rev shift kit to correct the problem as best as possible. Do some research or you may be disappointed. A higher ratio would eliminate this also.
I have an FMX in my 34 and like it. Have an AOD in my 53 with a 3:90 rear end and am happy since I put the kit in. I don't recall the size difference. Tom Last edited by Ardun; 11-18-2016 at 09:46 AM. |
