Have you read this:
From this site: click here
You should be able to get a 3.4 put in without a problem.
If your vehicle has a 3VZ-E engine, this kit allows the use of your factory transmission - manual or automatic. The R150 (manual) and A340 (automatic) transmissions are nearly identical to the units placed behind a 5VZ-FE from the factory. If you are using a manual transmission, the 3.4L engine needs to come from a manual transmission vehicle. In SELECT year models we have found a difference in crankshaft machining from the factory. In these instances an engine from an automatic transmission application will not accept a flywheel or pilot bearing. If using an automatic transmission vehicle, you will only need to be concerned with matching the correct ECU and wiring. We do, however, recommend that you acquire all parts from the same donor vehicle.
There are many discrepancies in factory wiring configurations from year to year. This makes it very difficult to match the ORS conversion harness to your vehicle. Once again, it is best to acquire all the donor parts from the same vehicle. Upon the order of your kit, we will need you to ship the donor vehicle body (dash board) harness and your vehicle engine (injector) harness as a core in order to construct the conversion harness.

From the ORS website:
The Off Road Solutions 3.4L Conversion kit is now available for 89-95 Toyota trucks and 4Runners originally equipped with the 3VZ-E engine and a manual transmission.
From my talks with Mike:
The whole deal will work a lot better if you use the newer tranny and bolt on gear drive cases.
If they do it in house, it sounds like they prefer to use the newer tranny which has more highway friendly ratios and likely way less mileage than your stocker.
It can be done, there are straightforward and practical solutions to your problem.

auto is possible, its already been done, 2 swaps done in an auto 4runner by my cousin and I. 4wd also.
also on our friends truck.
we even rebuilt 2 autos this weekend
you have to mod acouple parts on the tranny for better shifts.
also to make it compatible with the computer.
on ours, we also swapped to the newer 3.4l torque converters using acouple parts from acouple spare late model trannys

If you decide to keep the 3.0 go with the reman. I had an'88 reg cab with the 3VZ-E (3.0) that blew the headgasket. I decided to rebuild, and after teardown and taking it all to the machine shop, it ended up that the block was cracked in 3 places. I found a new block and did the whole rebuild, heads included for about 1,700.00. I did however do all except the machine work myself.

Do you think the new motor is a good idea since it will be drop in or would i be better off to just replace the head gasket on my motor now. If i go with the head gasket should i look for any particular brand on gaskets and what else should i replace while i have it tore down. Any advice would be great, thanks

If your not completely set on the 3.4L... A straght six is always an option as well. Then you have the option of having a turbo too...

Ok guys maybe i really need to do some more research. I really want to do the 3.4 swap but need to know for sure i can use my '95 tranny. I can get the 3.4 from a '96 Taco with the computer and harness and im an electrician so im sure i can rewire whatever i need to. So can someone tell me for sure it can be done with my tranny or not?

mattk, it will be possible to use your auto transmission. but....to make it work correctly with the new ecu for correct shift points, you need to mod and machine some parts and sensors on the tranny.
btw, do you have a 2wd or a 4wd?
if 2wd, you can just swap in a newer tranny. cause there is no issue with the transfer case.
but 2wd is no fun. 4wd, you have to use your old tranny, b/c of where the transfer case is positioned. and do the mods mention above. you wont get very satisfactory shifts from the old tranny, b/c its not made for the power of the 3.4. )I havent tried the 3.0 tranny with a non-sc'd engine, we built our tranny to run well with the trd s/c.
you may have to do alittle modding to the valve body and the shift springs for better shifts. i would recommend rebuilding your tranny also.

Ive got a 4wd and are the mods to the tranny things i can do myself or they more extensive than that. Iwill be running the motor without a s/c. I just really need to get this Runner back on the road. BTW my email address is keller9431@aol.com if you wanna email me instead. Any detailed info you have would be great in helping me with this swap. I need to decide quick the motor im looking at may not last long. I can get a 3.4 w/harness and computer for $1650.00 w/ 58,000 miles on it. But i need to make up my mind asap before it goes. Its out of a '96 Taco auto.

the mods to the tranny will have to be done by someone who knows what they're doing. you will screw up stuff if you dont do it right.
also a special part has to be made and some stuff machine on the tranny housing.
you can run your old tranny without doing anything to it. you will just have a CEL on all the time.

sc's or a new motor.
What is involved cost wise with rebuilding the 4wd auto tranny?

The price depended on the motor, ie used, used rebuilt, or new. Total with labor and parts, including hood scoop was starting about $8000. Then of coarse it went up for extras like

Why not just buy a high miles 3rd gen at that point?

When does it get too expensive to be worth the effort?

About a grand for a new tranny. Another $450 for the V-6 to gear drive transfer case adaptor then $200 or so for the t-case.
Yeah it is at least 8k, but if you have other mods on your truck that cannot be reasonably sold off or swapped to a newer rig, it makes sense. Figure if you get an engine with less than 50k, you are good for at least 150k on it. For me, that would likely be the time the frame had broken in half and it had become a tube car.
You are looking at atleast 8k and at least 2 weeks.
