Topic: W56 Tranny Swap Into My '84 Xcab 4x4: Shifter Fit?

[wrenchtech]

I want to replace the G52 in my '84 xtra cab SR5 4x4 with a W56. Currently the shifter on the G52 is far forward in the console and the t-case shifter is farther back. Will the W56 tranny shifter clear the opening in my trans tunnel? Will I need to change the t-case shifter? -- Matt

If you have a 85-89 runner, or 85-88 p/up single handle W56, you will need the cut up your floor board and converet your t-case to a top shifter.

A better choice is a twin stick style forward shifting W56 and t-case from a 90-95 runner, or 89-95 p/up. The handles would only be 1/2" rearward

Are you talking about an aftermarket shifter when you say "twin stick style.." or the stock shifter on the 89 - 95 W transmissions? 

Is the t-case you refered to,  from the 90-95 runner, or 89-95 p/up,    an R1FA, gear type t-case from 22RE powered vehicles?

I notice that the transmission chart on your website divdes the W56 transmissions into 1985 - 1991  and 1992 - 1995 types.  What's the difference between the two?  Thanks for letting us access your extensive knowlege on this stuff.  -- Matt

what marlin means by "twin stick" is that the '89-up W56 was forward shifted just like a G52 tranny in carbed 2nd gen trucks.  the t-case shifter is in the tailhousing of the tranny rather than directly on the transfer case like a top shift

***Threadjacking in progress***Are the forward shift G52 transfer cases and forward shift W56 cases the same?  I'd like to find a forward shift W56 and swap my G52 out.

Kyle_22r is right [again].

All W56 trans were only available with the gear driven R1FA t/case.

The 85-91 transmission family could be called the first design and was built very straight forward.
Begining in '92, Aisin Seiko, [the manufacture], released a new, streamlined, second design.
Shift shaft bushings, Reverse syncrow brake, Oil baffle, Internal magnets, Bearing and Syncrow improvements, ect.

These improvements resulted in better mileage, smoother shifting, and more quiet operation.

The quickest way to I D these trans is by the added vent that is located between the trans, and t/case handles on the 6 bolt base.

Unfortunately, the newer W56 shift rods are 1/2" shorter and must be changed as required.
I feel the W56 is 40-50% stronger than the early G 52 trans.

When installed in you truck, the trans and t/case handles would be located 1/2" rearward. Crossmember and d/shafts would all bolt right up

 Which rods are shorter on the 92 - 95  W56's?  The ones  that shift the t-case? Man! Now I'm wishing I did'n't sell off my '92 factory manual.  -- Matt

Do the R series have these upgrades, or did they get them at some point too? -- Matt
