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?

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.

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.

It was not as bad as I thought.

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.
