transmission and rear end oil

I use non detergent 30 weight in my '56 100M trans and 90 wt in the rear end. Do not know if that is the proper recommendation for a later BJ7 but sure you will get good feed back from others.

Mike
 
I use exactly the same in my 62 BT7. There's something about the non-detergent part that's important for the tranny and overdrive, and 90W is pretty standard for the rear end.
