Ryan, you will need the complete 2 wheel drive trans. It is a remote side shifting 5 speed trans with an aluminun bellhousing, cast iron front housing with a power take off option, then a cast iron center and finally a 10 bolt rear cast iron housing that has a land cruiser style e-brake drum on it.
The trans is called R452 and when I build one, the complete gear set must be used. It was never made for a 4 wheel drive truck so I must use the housings, shift rods, and output shaft from a R150F or R151F core.
It was used in Hino trucks and found behind the 2LT, and 3LT diesels. I have seen '88 thur '97 model trans.
It is also found in Dyna 150 trucks with the 3L diesel engine.
They also call it the R452 transmission.
Marlin, I think Mark's 4WD Adaptors
http://www.marks4wd.com/hiluxt.html is using the Dyna gearbox in their HD 5 speed transmission upgrade kit for the Hilux in Australia. The gearbox comes in the following ratios:
1st 5.15:1
2nd 2.87:1
3rd 1.50:1
4th 1:1
5th 0.83:1 or 17% overdrive.
Here's a pic of their conversion with a bellhousing for the Holden V8 engine
http://www.marks4wd.com/images/MFK715-MFK650-1.jpgOf course you probably know much of this information. But hopefully it will help other viewers. As seen the only part of the original Dyna gearbox is the portion painted black, and it indeed has a side shift mechanism. One of my correspondents from Oz was negative about Mark's conversion because of this funky (and sloppy linkage). In his opinion the internal top loader shift is the only way to go.
The R452 is also available in the Hino Dyna 4-093 Cab, Van Body, and/or Drop Side trucks with the Toyota 5L diesel engine. Unlike the 5L's offered in Hiluxes in Oz (September 1997 forward) coupled to W56 and/or R151/R150 gearboxes, the 5L's coupled to Dyna R452s used a different bellhousing. The R452 will not bolt to the Hilux diesel bellhousing, and as far as I know it's 2WD mode only.
My question is... When using the R452 gear sets in a R150F/R151F housing plus shift rods, and output shaft - what is the result of your conversion? A stronger gearbox or just a lower 1st gear ratio than the original? Filll us in please.
Wouldn't new or used Dyna R452 gear sets be available thru Marks (or another vendor wherever) without having to import whole donor transmissions? Have you determined the Toyota part numbers for the gear sets for the R452?
