Interestingly 08 SpecB tranny also lost oil pump (07 SpecB had it), but retained the dipstick.
So what's better oil pump or oil guides? Eliminating oil pump sounds like a downgrade. I found some old material when 6 speed was introduced and the oil pump was mentioned as a big deal to improve oiling over 5 speed trannies.
