Well me, plus 2 others that I know of, had very bad foaming with 30 wt non detergent oil in AH transmission; Castrol does not recommend this oil for transmissions.
Have some pix if anyone is interested.

I’ve always run 30W non-detergent, but I’m trying the 40W Russ put in.  I asked Russ about it, and he said he’s always used 40W.  Given temperature is not a factor in So Cal, the thicker oil may perform a bit better in the heat here.

     Through a reference from the list I am having Russ Thompson in Northridge, California rebuild my BN2 transmission.  It is a low mileage (10,000 mi. approx) transmission, but I wanted to be able to put it in and not have to take it back out again.  Good thing I took this precaution.  Russ found the overdrive stuck and would never have worked.  Today he showed me the accumulator piston.  The smaller center piston was scored from dirt or crap in the oil.  Russ replaced it with a one piece piston from a Triumph overdrive.  There was a huge spring below it.  Anyone heard of this?  He said engagement will be real positive now.  Even with the low mileage, the number 2 synchro was toast and will be replaced.  The other two were fine and will be re-used.  All the gears showed very little sign of wear.  The reverse gear had some surface rust on the teeth, but that can be blasted and it will be fine.  Getting closer to having the drive train is the car.

     I know I am going to start a discussion, but Russ recommends using 40wt motor oil for the transmission.  Anyone know what weight Redline MTL is?
