Just finished up the transmission swap on my 1982 truck.

I used a G54 transmission they came in 1986-1988 22r carberated IFS 4x4 toyota trucks.

The reason I used it was

#1 it was free and I couldn't justify buying a w56 transmission for it.
#2 It has way beefier shaft and bearings than the failing L52 transmission I had in it.
#3 It has a removable bellhousing so I can still do a Toyota Supra 5MGE or 7MGE engine swap on it.


I measured both the L-52 with the t-case to the back flange is 34 1/2" The G54 Transmission is 38 1/2" long measured the same way.

I basically had to get a longer front driveshaft that was 4" longer than the one I had. I used a IFS front drive shaft and modifyed it to be able to move more than 25 deg.
I used this tech to do it http://www.4x4wire.com/toyota/tech/cvmod/

The rear driveshaft had to be shortened by 4".

I was using a Budbuilt crossmember so it can be slid back and reattached using the back of the rear crossmember mounts and using a 2 5/8 - 3" 5/8 square u-bolt.

The transmission hooks right up to the 22r motor no issues same bellhousing pattern as the L52 pattern.
You can use the same clutch slave cylinder as well
I used a new clutch from a 88 to better match it to the 1987 g54 transmission.

Some pics of how the skidplate is and the ifs front shaft and redone rear driveshaft.





Still have to trim the u-bolt excess off and put a washer under the front bolts.

I think I have to buy a new rear driveshaft flange since this one is grooved and with a new rear seal is still leaking.

Also one note the G54 transmission pretty much bolts right into place.
However I have a 1" body-lift the transmission tunnel still rubs a little on the top of the transmission.
I could probably get away with just hammering the area behind where the shifter sits. It basically is rubbing where the top plate cover on the t-case is.
If you are running a 2-3" BL you should be fine.

right on, i've been kind of pondering tranny choices for my yellow truck as it's no longer a daily driver. almost thinking of swapping in an SM465 with OTT's adapters, but it'd get pricey. might just do a W56 and get a better pinion angle, and since i'm planning on dual cases some driveshaft mods are gonna be necessary...why not do it all in one shot? <img src="/forums/images/graemlins/cheers.gif" alt="" />

Well also another thing Kyle the G54 has a forward shift transfer case so the shifters all line up perfectly to the exisiting holes in the tranmission tunnel for them. You can find some w56 transmissions like that as well the w56c or w56d but they becoming harder to find in junkyards.

This info is right from Marlin's website.

The W56-C was installed into EFI 22re powered 1989-1991 Pickups and 1990-1991 4Runners.

The W56-D was installed in EFI 22re powered Pickups and 4Runners from 1992-1995.


You can find alot of w58's from 89-95 that are forward shift. I believe these were in alot of 22re trucks using the ADD system.
