The R 154 is hard to see but the gears are about 20% wider then the W 55 adding more strength in the gears
the input shaft is an inch longer but the disc splines are the same
the bearings are also larger in the R 154 on the left, its just an all round heavier trans
this is the R 154 on the left, the T 56 in the middle and the W 55 on the right
you can see the difference in shifter length
Excellent that you have posted this for people to consider. Do you have any internal info on the W58 and how it might be different from the W55? Also, I assume that the measurements you took of the two Toyota units was with the stock bellhousing. Since I've never seen one with the stock bellhousing on, does the input shaft end at the same place the bellhousing does? If not, how much shorter or longer is it?
And by the way, that T56 is HUGE! I thought my R154 was big. Do we also have a weight comparison of these units?
Do it in a Datsun!

Hey Bill, I just pulled one from a 84 Supra, paid a decent price BUT after getting home Looking at it closer I noticed that the middle seperator plate is aluminum..? From what I've read is that they were all steel
Either way, I'm sure it should handle more than the D50 trans right... right?? I'm not looking for 400hp or even close to that. Once I get your bellhousing, it's going behind my 4g61t. Hopefully around 250+hp.
Im not really familiar with the difference of steel/ aluminum plates Errol
the R 154 was built by Asian ( I think) and it have a couple varients, the 4wd had a shorther input shaft and the A 15 ( jeep model) had a very long input shaft
but as far as I know the Supra r 154 was only about a 6 year production run and they were all the same
i believe some of the earlier W5x gearboxes had alloy plates
they are still the same just alloy sandwhich rather than steel
some people say that makes them alittle less strong others say its negligable
theres a couple of good pages here with info on w series
Thank you for that info,
SO, I wonder what trans these AE86 drifters use? The earlier W series?
I just would like to know of what vehicles had the shifter extensions that were longer.
I've mailed several peeps but NO one seems to know..
I would just think that the longer 'nosed' cars (Cressida, Supra) would put the shifter further back.
And would think that being a strong trans, it isn't used in the 5spd trucks. Not every yard has a supra, BUT every one has a toyota truck!! (or 50)

i know the jza80 supras have the biggest exstension housing, it is a cantilever style one which ends up having the shifter about 20cm back off the end of the gearbox
heres a pic of all the shifter styles
top row is w50 bottom row w55-58
the respective lengths from gearbox-bellhousing mating surface to shifter are 18" 18" 19" 20.5" 20.5" and 21" then the jza80 one on the far left dunno the exact measurement on them tho sorry
I've mailed a few 'Toyota' people and either they don't know which vehicles the longer ones came in OR it's just so common that they don't feel like answering...
Soljah, Thank you for that.. It amazes me how people can find things like this.
Plus, it looks like it wouldn't be that hard to make a short shifter either.
Getting the engine bolted in is about 10% of the way there.
The next 80% can go quickly with help and skill.
That last 10% takes about as long as the 90% that came before it.
I've got this job in DC. Its only 8 hours each day, but it comes with a jam packed social life. I'm enjoying every minute. Being 2 hours from my parents makes it next to impossible to work on my car, so its rarely on my mind. I'm still planning on updating/fixing the website, but can never seem to get going on that.
