Thank you for your reply.

My curiosity is largely academic. I do tend to fill, dip, fill & dip until
it's right, but I would like to know where the official start line is!

Offhand, I'd believe the workshop manual first.  If you're doing a
drain-and-fill, you don't know for sure how much residual oil is left so you
have to go by the dipstick anyway.

1)      My car's Driver's Handbook page 7, (AKD 3915A) tells me that:

my MkII BT7's gearbox takes 5.75 imp pts (6.90 US pts) 

its overdrive takes 1.33 imp pts (1.75 US pts)


2)      My BMC Workshop Manual (AKD 1179D) tells me that:

gearbox               4.0 imp pts (4.80 US pts)

Total gearbox, overdrive fitted, 5.25 imp pts (6.30 US pts)


3)      My Haynes manual goes for:

Standard box:- 5 imp pts

With overdrive:- 6.25 pts              


4)      My Autopress manual (Kenneth Ball) goes for:

Standard box:- 5 imp pts

With overdrive:- 6.25 pts


ie only Haynes and Autopress agree.

I've had this Healey for +/- 20 years and I've never noticed these
discrepancies! I seem to have survived by using the dip stick, but I'd bet
that I've overfilled more than once.


Any ideas? I don't recall this coming up before.....




(And I didn't mention Redline once!)
