I am going to do a 7mge swap and currently have everything to do so except it will be swapped into a 88 v6 truck and the tranny is a problem. Is the W56 totally interchangable with the r150 (i beleive that is what i have currently). I dont want to change driveshafts, alter the floor of the truck or anything major im just looking to swap the tranny, throw on the supra bell housing and bolt the engine up. Am i in luck or am i screwed.

7MGE powered Toyotas like the Supra and the Cressida use a W series tranny. If you want to use a W56 tranny in your truck you will have to use a bellhousing from a Supra or a Cressida It is pretty much a bolt-in job, except that the clutch slave cylinder mounting face on the new bellhousing will be on the driver's side. The W56 is adequate for the 7M's power output, but the R series transmission is twice as strong, its just that there is no bellhousing that will both bolt up to a 7M motor and acommodate the short input shaft on the R150 transmission. The Supra turbo uses an R154 RWD transmission, so you would think you could use that bellhousing to mate an R150 truck transmission, but it's too deep. The R154 has an input shaft that is about an inch longer than the R's in the trucks. And you can't swap the input shafts because the gear sets dont match. Marlin Czajkowski of Marlin Crawler fame has told me that the believes an R150 out of a Tacoma would fit, although the output shaft on the Tacoma R150 is a quarter inch longer than the Supra R154 shaft. Nobody I know of has tested it yet. And of course you'd have to get an adapter to run a gear type transfer case behind the Tacoma transmission, just as you would with your current R150. The easiest route is to get a W56 tranny and a gear type transfer case. The only complication there might be some trimming of the trans tunnel shifter opening. -- Matt

so basically what your saying is get the 4 cylinder tranny and it will involve noting more that geting a supra bell housing and and bolting everything up. It almost sounds too easy, i was very comcerned about the driveshafts. I wasnt sure if the lengths would work out or even if the flanges were the same. I found a trans and transfer in a local yard i can grab, its an 87 would that be the gear driven tranfer case you stated would work? Once i conquer this tranny problem i should have everything. I have an engine, all the stuff under the hood, and the ecu and harness plus i might have a wrecked 88 for a few hundred bucks this week. That should be plenty of parts plus a few spares. I just want to have everything before i pull the v6 out. Such a shame i only rebuilt that v6 a year and a half ago.

I don't know about the driveshaft lengths. On 22RE trucks you can use 5MGE motormounts out of a Cressida (engine half) and bolt right up to the frame half of the 22R mounts. I've never done the swap so I don't know how it affects the driveline placement. I think the 3.0 trucks have the motor mounts in a different place so you might be welding up some custom mounts.

The '87 should have a W56 tranny and a gear type transfer case if it had a 22RE motor. If it had a carb motor it will have a G series tranny which is not as strong.
