66-RFE Trans Fluid Chart

DannyMK2 · Feb 6, 2017

anybody have access to the factory service manual and can check to see if there is a fluid temperature chart that shows the proper fluid level at different temperatures? the service manual for the older trucks used to have this and i would like a copy of this page for the 66-RFE if possible. thanks.

My AllData disk only goes up to 2012 on the HD trucks. If I pick the 66RFE service procedures it shows a chart for the 68RFE. I don't know if this is intentional or not.

Anyway, here it is if you want it.

I have the current Alldata online account and oddly enough, it also shows fill data for a different transmission when I click on the 66RFE. Either they are the same, or Alldata is messing up. This is what they show for a 2016 Ram 2500 w/6.4:

thanks guys. these are good enough to answer my question.

Although, i do find it pretty odd that they are showing two different charts for the same transmission, (even though they are pretty similar). im assuming the HOT marks on the 68rfe dipstick are also when the trans is at 180 degrees? if so it would be easy enough to measure the dipstick and see which chart is more accurate. 00R/T would you be able to confirm that for me?
