Mf6480, looking in the transmission.

Thought they were all capable of 50k, but enabled through software. I'm told D6 40k won't engage 4F ratio?

see my post further down.

D6 40k & 50k isnt identical 4th gear ratio is taller in the 50k version thats why they will clock 56k flatout
40k D6 has limiter on 4F around 1900revs which its only doing 44k but even if you could rev it full throttle it would never get too 56k
old 32speed Dynashift flatout in 4D is only around 40k 3000,6100,6200 & early 6480s & bigger series likewise.

A dynashift 64 series doesnt rev flat out to get to 40k, about 2000 revs

That would explain why 4A feels a bit long legged to pull away loaded, if 50k is higher geared. I wondered if a 40k tractor feels the same.

Here is the reason 40k D6 gear 4A is slower than 3F in a 50k D6 its higher !!!
Ive had both versions
In all honesty massey should just have made the one trans & if 40k was a limit for whatever reason just limit its revs in 4F which of course in the 50k version they dont.

yeah correct. there is the taller ratio as the 40k D6 at 1900revs on the limiter is 44k its nevre gonna do 50k is it.
if you can remove the limiter & gain the 300 revs then maybes.
Has anyone had the done tho?
Its like the hour clock cant be touched.... oh yess it can
Not that i know how. but i just know its been done.
