Just another query:
The other day Ii notioned that Toyota gearboxes are designated after the
original engine they were designed to go on - hence T-50 was designed to go
on the 2/3T engines and later added to 4A, 1S etc. And the K-50 went on the
5K, but later the 3A......
Someone (Matti?) caught me out by asking what the W-series engine was.....
Ok - I got talking to a guy the other night who worked on gearboxes for a
living (altho I qualify this by saying it didn't look like he made much of
a living....) who said that 'the Supra box and a truck box (Dyna?) were the
same box - right down to ratios' ............
This leads me to think of 3 things....
1. It is conceivable that there is a W series diesel truck engine? (not
that it is really important).
2. Is it possible that the Supra and a 1.5 ton diesel truck have the
identical box and ratios (both would need to handle a lot of torque and
ideally be 'close' ratio to suit spirited driving/narrow power band?) even
with radically different engine rev ranges and diff ratios/tyre heights?
3. If this is true, then truck gearboxes are most likely heaps cheaper
(altho maybe more worn).......
Just some more random thoughts!
