Transmission interchangability - Page 2 - Toyota 4Runner Forum

Brennerkevin · 02-09-2019, 10:11 AM

I also have a A340 trans question. I have 2 used trannys and they are both out of 2 wheel drive 4runners. 1 is a 2000 and the other is an 2001. The only difference in the 2 is the 1 uses a kickdown cable and the other is electronically controlled. My question is, can I swap out the valve bodies and use the older trans in the 01 vehicle by using the newer valve body?? Any help would be greatly appreciated

I hate when the perfect question is asked and then a field of crickets for days.

If you're wondering about what transmissions work with what year it's pretty simple. The valvebody in the A340 is different 96-98, 99-00, and 01-02. While you probably could get a 96-00 working the 01-02 A340 is electronically controlled and the valvebody is completely different and a 01-02 will not work with anything other than a 01-02 A340.

I will tell you, that the transmission from a 1st gen sequoia will work in 01-02 trucks.

You need to change the bell housing though.

It’s the same transmission from the bell housing back.

Sorry to necro a very old thread, but I'm needing some information on this. I have an 02 with an A340F that I'm having a ton of trouble finding a decent one in the junkyards here. But there are tons of 1st gen Sequoia A340F's out here with low miles for cheap. Is it really just so simple as swapping the bell and linkage? I know the torque converters have different part #'s, which converter would be needed? I've been trying to find some info on this or a write-up, but no luck. Thanks

Can't help you with which Sequoia transmissions would work, but I can tell you what I learned during my 2WD to 4WD conversion on my 2001. I couldn't find a good 01/02 version, but I was able to swap the internal valve body from my bad 01 transmission into my 'new to me' 98 version.

The 96-00 versions use a throttle cable. The 01/02 versions use a solenoid for line pressure control instead of a cable. When you swap the internal valve body into the pre ‘01 transmissions, it converts them into the 01/02 electronic version. Finding a 96-00 transmission is way easier!

The following link describes it all:

Hope this helps.

What did you do with the throttle valve when you put the newer valve body on the older trans? Wire it WOT?

Once you swap the valve control body from the 01/02 into the tranny, it comes with the wiring harness so everything connects as it was before. I hope this answers your question. The link provided gives all the info.
