So how come you don’t see many builds using Toyota automatics? I am buying an 89 Toyota 4Runner with a 3.0 V6 and an automatic. I'm just wondering if I should be looking for a 5 Speed to replace the auto with or can the auto handle some 31's and some fire road cruising, general use and camping?

I don’t see why not but it just seems like most people avoid the Toyota automatics like the plague. What do people know I don’t.

Thanks
Josh
 
hey can not speak for all toyota autos but i baught a used 90 4runner and wheeled it once comming home from work one day the trans split the casing fluid was running evey where call junk yards to find a new one finnaly found one on the west coast called them the would not ship it the guy said they used so many different ones that he ate too much shipping charges because them being wrong but check that fluid well before you buy drive it before you check the fluid.
 
nothing wrong with the auto you just cant get t-case gears for it. Sorry you bought a 3 slow it is generaly a weak motor but you did get the best year.
 
it realy went slow when the trans cracked i checked the fluid on the lot should have known somthing was up looked and smelled fine will not buy any thing from them again and i will stick with the old true 22re from now on
 
i have the 22re/auto for now and for fire road,camping easy to medium wheelin it will be fine but it does waste power and doesnt like the angles
 
ya know, I have heard the same thing about the auto's, that there a poop. However after wheeling alot with a 5 speed I whish I had an auto. To e I cant see a problem with the old slush boxs since you can get crawl boxs for them these days. you shouldnt have power issues since you the extra juice of the 3.0. best of luck to ya, i would keep the auto if I had it.
 
I run an auto in a some what extreem truck. I have no desire to wheel a stick! and neither do most of my friends now.

All of the above "problems" I have never expirianced.
 
The trannys are good AFAIK.

The problem is the secondary hydraulic driven TC that I've read, acts like an additional torque converter and the fact it's being driven by a weak but dependable little 4 or 6 cylinder....

Other than that I know of very few problems.



you can get an adapter to bolt a gear driven TC to them and pic up a few MPG's.

Also something about valve body sizes between years...IIRC the older ones had smaller valve bodys and at some point they were enlarged...


Just don't gear it based off the 5 speed trucks, 2MK all ATs had LOWER gears. I'd jump down a gear in comparison to the 5 speeds...5:29's for 33's, and 5:71s for 35's...Don't worry, the OD gear is a 500 rpm drop in ATs and a 250rpm drop in the 5 speeds.

Wouldn't go bigger than that unless you like the fact you could be in the middle of nowhere and have a tranny failure...Allison's they are not.
