5-Speed Transmission Swap for my 85 Toyota 2wd Pick-up
« on: Apr 24, 2006, 12:16:34 PM »
I'm recently the proud owner of an 85 Toyota pick-up that is equiped with a 4-speed.  Sometime in the future I'd like to swap to a 5-speed tranny.  Does anyone know which 22r 5-speed trans' can be swapped to an 85?  Out of my options which would be my best choice?  Thx.

What is your current 4 speed trans?
It will be stamped on the id plate above the valve cover.
I would guess a W46.
A W55 or W56 5 speed 2wd trans will bolt right in.

My truck is currently residing in a hobby shop,where I wrench on it personally, awaiting its head.  They're closed on Mon n' Tues.  I'll get back to you on that.  I live in San Diego...  I notice that some of tranny's from the 22r family have transfer cases, obviously for 4x4's.  Are the transfer cases an integral part of those transmisions, or can they be removed and used for 2wd applications?

if its got a transfercase, its a 4x4 tranny... it can be used as a 4x2 tranny, but you will need to source an iutput shaft from a 4x2 because they are different

That's good info to know and I'll consider it in the future, although I think I'll stick with 2wd specific applications.  So if indeed my tranny is a "W" series, I can use any other "W" series trans'?

Worked on the old girl today and almost have her back together (head gasket replacement).  I found out that I have a w46.  Since my tranny is a "W" series, does that mean I can use any other "W" series trans'?  I was lookin at some pictures and it seems as though the W and G series bellhousings share the same bolt pattern and according to Marlin Crawlers website, are dimensionally the same in length, as well as both having a 21-spline input shaft.  I would try to contact Marlin Crawlers for more information but they do not list an e-mail address on their website. for a definitive answer please.

You're best options would be to either A: buy whitemans w55, or B: go to the junk yard and try to find a 5 speed out of a 2wd truck from 84-95 (should be either a w50 or w55), or find an 82-85 celica and snag the w58.  The shifter for the celica tranny will be a couple/few inches further back, but it will work.  Don't consider a 4wd tranny swap as it's just going to be too much work for what you get, and you'd be better off selling a 4wd tranny if you have one and buying a 2wd one for less.

Yup, I think it might go back to mid to late 70s in the celicas.  I put an 81 celica tranny in my 81 2wd truck and only had to change the shifter hole location.

i didn't know celicas ever got the W58?  i thought that was a supra-only tranny behind the N/A six.  it'd still work behind a 22R with 4cyl bellhousing, but the ratios are wider than most of the other 5 speeds(1st is lower, 5th is higher), good or bad depending on your application.
