2000-02 A340F vs pre-00

I picked up a 2001 sr5 transmission including transfer case off Craigslist for $350 a while back. Only problem is, I drive a 1996 sr5 4runner. The easy solution would be trade it for an older model transmission. Before I do that I'd like to consider a few other options.
If you don't know, the earlier models have a kickdown cable. The later models have an electronically controlled kick down. So would I be able to swap these two assemblies?
What would be another solution?
I realize this is an odd idea, but I'm not totally convinced my money was wasted.

Welcome to the forum, Tommy. Here's your answer:

The compatibility issue lies not with the transmission, but with the valve body, which is essentially the "brain" of the transmission. Much of the information below is a re-post from a writeup in my build thread.

The early model years (1996-1998?) used a VB like the one below. Notice the overall length, which is shorter than the later versions, and the presence of the tubes (there should be two tubes, one has been removed in this photo) on the left hand side. The tubes are transmission fluid paths that were integrated into the actual VB on later versions. Also note the connection for the transmission kick-down cable @ bottom center. The other end of that cable connects to the throttle body and controls line pressure in the transmission @ various throttle positions. Last, notice that there are only three electronically controlled shift solenoids. Two along one edge and the third at the end near the tube.



The mid generation model years (1998-2000?) used a VB like the one below. Notice the increase in overall length, and that the VB now encompasses the fluid paths that were previously separate tubes. Also, notice that there is still a connection for the transmission kick-down cable to control transmission line pressure. Finally, there are still three electronically controlled shift solenoids, but their position on the VB has changed. All three solenoids are now aligned on one side of the VB.



Last but not least you have the late model VB (I know for sure this one is found on 2001-2002 model years). This version retains the overall shape and size of the previous version, but there are changes to the hydraulic controls. Where line pressure was controlled manually by a kick-down cable on prior versions, it is now controlled electronically by the ECU using a 4th solenoid, the SLT solenoid. This goes hand in hand with the drive-by-wire feature found on the 01-02 models. Take a peek under the hood of a í01-í02 and youíll notice that there is only one cable connected to the throttle body, which is a failsafe throttle cable. The transmission kick-down cable is eliminated on these model years. This version also gets a 5th solenoid, which is the Shift Control Solenoid, however it is not electronically controlled. The two new solenoids are visible at bottom center, where the cam and kick down cable were located on previous models.



You will not be able to install the transmission from the '01 into your '96, due to the presence of the SLT solenoid on the '01 transmission valve body (and the corresponding lack of provisions for a kickdown cable), which the ECU on your '96 will have no means of controlling. Also, you will not be able to install the valve body from the '96 transmision into the '01 transmission because the fluid paths are laid out differently, due to the '96 valve body having the separate tubes, as pictured above.

You need to get your hands on a transmission that came from a similar model year 4Runner ('96-'98) that has the same type of valve body and provisions for a kickdown cable. The only other potential solution would be to pick up a transmission from one of the mid-gen model years, which also have the provisions for the kickdown cable, along with the updated valve body. However, I'm not even sure that would work because there maybe be differences between the solenoids on the two versions of the valve body that would result in compatibility issues with the ECU.

Hope that helps.

Also noteworthy for future CL buys that a 2-5 minute phone call to your dealership parts department would have told you a simple yes/no on compatibility.

Great info though BFAD. I read about the VB differences in your build thread and even after such a detailed explanation I'm still a bit baffled by it all.

Good, practical advice for the uninformed among us. That's the first place I would have looked for reliable info, rather than posting on a forum.

I love how Mr. Mynameistommy510 never even followed up on this thread... which is a perfect example of why I normally don't respond to random question threads posted by new members.

I fixed my notifications and have become more active on the forum. Luckily the seller of the transmission knew about as much as I did about the A340f, this transmission has a mount for a kickdown cable indicating its from an earlier model 4Runner.

Your information was not wasted! A Google search led me back to this old post, and I hope it helped other people in choosing a replacement transmission. Thank you for your extensive and helpful post BigFish

So I have a 2001 and I found a 2000 transmission. Will this not work in my truck. Both are 4x4 from a 3.4l engine. I understand the transfer case is different but is the transmission also different to the point this can not be done?

oneal48 - From reading this thread it sounds like you need the electronic kickdown version. I have a 2000 and and am looking for the trans you have! heh

I wonder if the tundra a340f like this one Automatic Transmission Toyota Sequoia 2003 03 2004 04 4x4 693787 | eBay would work for you if you could switch valve bodies. Ive been reading and it seems that the tailpiece and the transfer cases are interchangeable. I wonder if the bellhousing is as well.

did many searches, Need clarification On A340f Transmissions - Tacoma World Forums

Since the kickdown is electronically controlled wouldn't there be a need for the trans ecu and the main ecu also?

Im in the process of swapping in a new to me used tranny. The new one had its kickdown cable cut when it was removed from the truck. I cant seem to separate the kickdown cable from inside the valve body. I tried prying to get the pin out but I ended up breaking a small piece off and decided to stop before I do any more damage. Does anyone know how to remove the kickdown from the valve body?

I swapped the valve body and that worked fine.

Bit of a revival here specifically to 01/02 4wd Trans...

Does the SR5 4wd and 4wd trans use the same ECU ? 2001-2002

Installed a '02 used 4WD trans into a '02 SR5 4WD Sport ED and the shift from 1st to 2nd is stretching to about 3100 rpm, any throttle. Reverse is delayed, sometimes it has to rev like a manual to move back. Fine is all other gears

Any insight will be helpful

Reverse slow to engage is usually a problem with seals. The piston to engage is not pushed because the cylinder is leaking, especially when cold. Shifting out of second could also be line pressure, although controlled electronically, it still has to have good enough sealing to work correctly. I'm not a transmission guy, but it sounds like you got a bad trans there.
