Topic: 3rz build

[MAGIC]

I am going to swap a 3rz swap into my '85 yota pickup. I want to buy a complete wrecked vehicle so I have all the stuff including wiring harness, computer, exhaust and etc. I need to know if the trans that came with the 3rz was better than  my stock 5 speed? Should I swap the new or leave my old trans in. There is nothing wrong with the old and I have the marlin clutch which works great. I have dual transfer cases with the forward shift.
Also, If I keep the old transmission, do I have to buy a different bell housing or will the 3rz bolt right up to my existing trans? Any info will be appreciated. Tom Burt.

If your truck came with a w56 tranny keep that and you will have to swap the bell-housing from the 3RZ. Or there is info on making a HD tranny. Just read up

Thanks! Next question is how do I know which tranny I have?

Go to mc store and click on transmissions. Scroll down and click on trans gear ratio chart. Scroll down and you will see a table that's what year of truck had what trans.

If your rig is 85 efi it should have a w56-a if it's carb chances are it's a G. W56-a top shift G series fwd shift

22RE's came with the W-tranny. 22RET had the R151,22r's had G's. My 87 runner has the w-style with a forward shift T-case bought a  adaptor and found a top shift of a 1983 toyota with an L-style tranny.

Are the W series transmissions better than G series?

[Tungsten Slayer]

I've used the G series before with no issues, but the W seems way more popular.  I have heard it is stronger or has better gear ratios, can't remember

[emsvitil]

R's are stronger than W's which are stronger than G's

Also W's are stronger than L's

Not sure if L's are stronger than G's or if G's are stronger than L's........

I ran a G for awhile, i wore the bearings out but never broke anything in it..

I still need to know about the 5 speed that comes in a '95 to '04 Taco.  Is it any better than the w56 that is in my 85 22r? I plan to buy a wrecked Tacoma and stake everything needed to do the swap. I was wondering whether I should use the w56 or use the trans that comes in the Tacoma. Maybe I can't or shouldn't use the Tacoma trans. I don't know. Anybody know the answer.

the output on a W59 trans that comes in 95-05 Tacomas with 2/3RZ is 26 spline.

[Crunchy Taco]

using the w-56 will save you from buying an adapter to run gear drive cases on the taco tranny...w-56 all the way...

[Cheesemaker]

Use the W series trans (or if you can get a R151F) because you are gonna need the passenger side drop transfercase.   Unless you get a custom front axle with the diff on the drivers side.

I have a 99 tacoma 3rz harness and computer as well as the bell housing you will need to go to either w56 or an r series pm me for details
