I know most of you guys have no problem swapping out transmissions and motors, for me its a different task but I'm willing to research and try doing it myself that's why I here today. I have a broken tooth on my reverse gear, 91 pickup 22re 5speed 4x4. has the W56-C from what I can tell from the door tag and web sites. I located a transmission and transfer case all bolted together from another 91 the guy didn't know what type it was but from the pic's they sent me it's seems to be a 5sp G54 from comparing the pic's on Marlin Crawler inc.

I'm trying to find out before I buy it, If it will fit, this is all new to me which I think it will fit, but not for sure, every thing seems to be the same gear wise, but there is some differences as to a single shifter plate on top and electrical connections on the side of the W56 compared to a double shift plate on the G54. I have tried to research this before posting, this is one of the sites off this forum with a lot of help full info

Can any one out there jump in and maybe tell me if these two trannys will swap out OK, a W56 bad reverse for a G54? I'm thinking the speedo cable might be different and maybe the connector for the 4x4 indicator light and backup lights ( and I'm guessing at all this guys ) but from the pic's the wiring is a little different on the G54. Just not sure what I'm gonna run into.

If the new transmission is out of a 91, it won't be a G54, it will be a G58, with a chain drive transfer case behind it. I'm pretty sure it will work to swap in if you swap both the transmission and transfer case at the same time, because I am trying to go the other direction right now. My 4runner has a G58/chain drive t-case, and I'm trying to get a forward shift W56 or maybe a G54, both of which will use a gear drive transfer case. The down side of the chain drive t-case is you can't regear it, and I would like to have a t-case with crawler gears in it.

First of all Thanks for the Reply ,,,, I agree, If It WAS a 91 it should be a G58, I think the seller was not sure of the year of the truck it came out of. According to The pictures he sent to me I'm pretty sure the transmission is a G54 and not a G58 comparing them to the pic's on the Marlin Crawlers web site, maybe I need a second opinion from you guys, but all I've got to go on is these pictures and most of you on this forum are really good at what you do, so I value your
opinions.

So in your opinion,,, If this Is a G54, could I drop my W56 tanny and tr/case, and swap it out with the older G54 tranny and tr/case? If It Is a G54? with out any issues? or any other cable, electrical, hookup problems.

You can tell if it is a chain drive or gear driven case by the number of bolts holding the back of it together. I believe this info is on Marlins site. The G54 is lesser transmission than the W56, but will swap in place. I swapped my G54 for a w series a few years ago. There are a few issues you will need to address. First is the rear output. The bolt pattern might be different than what you are running, either swap the output drive flanges or order the triple drilled flange from Marlin. The second issue is Floor board clearance. If I remember correctly the G54 has the shifters mounted slightly farther forward than the W series. You can always just cut the floorpan but will end up with a small hole in back of the shifter boot and trim ring that looks ugly. All the electrical connections on the transmissions I swapped were the same. It was an 85 G54 and the W56 was from an 87 I believe. Even the throttle cable worked

Yeah, that looks to be a G54 or G52.(same thing really)
Considering they are both forward shift (w56c/g54-52) there should be no problem. The only think i can think of being different is the boot.

Thanks for your help. I'm thinking I'll stay with the W56 transmission, either rebuild the one I have or maybe I'll get lucky and find one.

I know this thread has some age on it, but I thought I would bump this instead of starting a new one.

I have a friend im trying to help out, and his 91 toyota 22re's transmission went out. I am thinking its a w56-c. A guy I wheel with has a G54, and I want to make sure the G54 will work in the w56's place. I have read the above post, and looked over marlan's website, and want to confirm the shifter and shifter hole differences. This truck is a DD, so a slightly weaker transmission wont be a big deal, but cutting the floor pan is.

Having a G series trans in mine, I wish I had a w56. I believe the G series trans were only put into the carb'd (22r) trucks and EFI trucks with ADD (G58). At least as far as the 4wd's go.

With that said G52/G54's were all forward shift. 89-95 W56 were all forward shift. Therefore they should swap. But personally it's not something I would do. One main reason is I do not like the 3-4 shift. Big difference in rpm change. Pretty sure the w56 has a better 3-4 shift.

I noticed that there is a ratio difference, However I dont think it will really matters to the owner. Did you swap from a w56 to a g54? If so was there and floor board mods done?

No mines a carb'd truck G54 is the original trans. Lets put it this way on the highway I turn about 2500 in 4th gear. Alot of times it's not enough and I have to shift to 3rd. (33's and 4.10s ) Which jumps my rpms to 3500. IMO that's a big difference in a gear change. I know these engines like to rev, however it's not a comfortable feeling. I wanna say the 3-4 gear change is a tad closer on the W56. Just haven't done the math to figure out where my revs would be if I were to swap to a w56. I'll wait for that after I get my 4.88's in. I might be able to look past that 4-3 shift as I will be turning a little higher in 4th gear with the 4.88. And heck I might not even have to use 4th and have my 5th gear back. lol.

Now keep in mind this is also a carb'd truck. And EFI has a tad bit more power, but I am not a stock engine either so it's putting out more then a standard carb would. And is extremely healthy with only 15,000 miles on it. I have other issues that contribute to my lack of lower rpm torque too, but that's a little off topic.

If I knew exactly why Toyota put the W56 in the EFI and the G52/54 into the carb I'd be able to comment whether or not it's not only a gear/power difference but I am also incline to say the W56 is also a stronger trans. So reliability of a g52/54 behind an EFI might come into question if strength was a factor in why they switched. I doubt it though since G series went behind an ADD efi truck.

This kid is running factory size tires and stock gears.

lol, so was I when I first bought the truck. Still didn't like that 3 - 4 shift.

With my driving style, I like to keep revs as low as possible, so in town I try to stay under 1500-2000. I shift at around 2500 which is alot lower then alot of other people I know. With the g54 I have to stay in 3rd a little longer then I would like. But again that's just me. You can always put it in there and see how he likes it.

My original point was just to have you realize it's gonna feel like a completely different truck with a G series trans in it and how I feel about the trans having it in my own truck.

4th and 5th gear g52/54 vs W56 are identical BTW so on the highway it shouldn't feel much different as long as he doesn't have to deal with alot of hills and mountains like I do.

2nd is actually a little taller then the W56 so if he's a kid he might actually like the little extra ooommmph in 2nd compared to the W56.
