I have a 1991 4Runner with 3.0 V6 and ATM. The t-case is no good.
Is it easier to separate the t case from the transmission in or out of the truck?
Never owned an automatic before ... thanks

I don't know that one. My 89 is a 4 cyl/auto, but I've never had to pull it out.

It seems easy enough to separate in the truck. Just have to remove the cross member, shift linkage and bolts holding tranny and t case together.
Im sure somebody knows ...

If the auto transmission is good why take it out? Taking the transfer case out is not to bad. Putting it back in can be difficult,the transfer case has to be completely lined up with the transmission in order to get it back together. The case will bind up,and there is a seal that can be easily ruined if is not done right. Don't forget the fan clearance between the radiator and fan shroud. Drink the beer after not before you start. If everything goes well don't forget to go to church Sunday. - Good luck

When you remove the cross member and lower the case there is a chance the fan position can change resulting in the fan blade getting acquainted with the fan shroud. I make a habit of checking all vehicles,when I R&R transmissions,transfer cases,clutches, etc. Rum probably works better,same result and less trips behind the garage.

I hate to ask why,but here goes WHY? The answer to your question is NO. The 4 cyl & 6 cyl are different. If and when you try to locate a different 6 cyl automatic transmission you need to know if your vehicle has the auto disconnect front differential or not.

Because the auto tranny in my V6 4runner is no good. I have 2 auto trannsmissions from 4cyl's. So i wanted to know if i could swap one of those in.
Not alot of info is out there on the net about these transmissions but what i have found out is that NO 4cyl trannies will not fit in the V6's. Im not sure why. The bellhousings are different, but im not sure what else.
Anyways i think this answers my question.
Also, it doesnt really matter about the ADD. This truck has a SAS so no it doesnt have it.

Yup.
Dont think it was the transfercase as everything looked good. So must be in the tranny.

Located source of the problem/noise. Internals of the torque converter fell apart.
Simple question: Are the 4cyl and V6's torque converters the same?
Please answer ASAP. Thanks.

Simple answer - NO. Finding a used one can be difficult. If you find one I would have it flushed before installing it.

A rebuilt torque converter for a 1991 Toyota 4 runner with a V6 isn't to bad. The cost - $115.00 - Plus -$20.00 S&H. No core is required with a 1 year limited warranty. Go to Torque converter1.com - or call -562-644-1534 and ask for johnny

Thanks for your answer.
Whats the reason why? Just so people know.
I actually recently found a V6 one so im good to go.
Also to answer my very first question. YES you can service the t case while still on the tranny. Its actually incredibly easy.

A couple of reasons - # of splines - flex plates are different. When you fill the transmission - Don't add the total amount of AT fluid at once. Add about 1/2 the total amount - start vehicle run far a few minutes - shift through the gears a few times - recheck the level - add fluid - repeat process until full. The dry fill should be 7.6 quarts of dexron 11 ATF. The transfer case uses - API GL4 OR GL5 -SAE 75-90 Or a full synthetic gear oil 75 w -140 its costly but in your and my area its worth the cost. The case holds 1.2 quarts
