What is the difference between the W56A and the W56B

[MiniSimp]

W56-A Transmission

With the introduction of fuel injection in 1985 4WD trucks, Toyota also introduced it's new W-Series transmission. The W56-A was only used in 1985 EFI Toyota Pickups and 4Runners. W56-A models have an aluminum center plate and a single shifter (transmission) atop it's rear housing. This transmission is 25 3/8" long and weighs 85 lbs as pictured. The center of the trans shifter is 21" back from the front edge of the bell housing.

Years used: 1985

W56-B Transmission

The W56-B was used on 1986-1988 EFI Toyota Pickups and 1986-1989 EFI 4Runners. This model can be identified by having both a cast steel center section and a single shifter. This transmission is 25 3/8" long and weighs 85 lbs as pictured. The center of the trans shifter is 21" back from the front edge of the bell housing.

Years used: 1986 - 1989

Either way, they are both good. Have you thought about having Marlin rebuild yours?

an 85 carb should have been a G series.

[Rubijon]

an 85 carb should have been a G series.

The guy I got this truck from said he changed the transmission. Now that I am going with dual cases I pulled the t case and part of the trans came off with it. It was JB welded on. I want to strangle the guy I got the truck from. Now I guess I need to figure out what transmission to go with.

[Duffil]

oooh broken extension housing.  Check on the MC trans page to be sure of what is under there now.

[Rubijon]

From what I can tell There is a W56 I have not got it out of the truck yet I am going to start in about 30min. I dont know if it is an A or B

[MiniSimp]

Why don't you call Marlin and see if they have the part you need to fix it.

[Rubijon]

I have been trying to call Marlin and I get no answer. Did they change there #. I call the # off the web site and some lady answers the phone.

the w56a and w56b are interchangeable with no modifications, when i replaced the w56b that went bad in my 87 4runner (bearings) i used a w56a from a 1985 4runner, bolted right up with no problems or modifications.

[Rubijon]

Sweet.

[Rubijon]

pulling out the transmission is a pain in the ass

[TIMS89CRAWLER]

pulling out the transmission is a pain in the ass

yes sir it is

[Rubijon]

It was not as bad as I thought.

[Plekto]

My favorite method that I have seen to remove it is the 2x6s and straps and lowering it.   But, yeah, it's not a terribly hard thing to take apart. 

[Redbeard1]

I just pull them and stab them by hand they only weigh about 90#.... unbold it get ryt under it with a creeper put it down on your belly and roll out.

[Rubijon]

I guess thats one way of doing it.
