Did you trace that off of the 4WD tailhousing?  Let me see if I can trace mine - my buddy can scan it for me so we can have an actual drawing.

Sure did!  One thing I thought of though...I'm not sure how difficult it would be to mill the front in order for the "lip" on the tranny to fit?

Hey Cebby,
Have you "opened up" your 340F tranny yet?  I'm wondering how similar it is to a 340E?  If they're basically the same (IRT solenoids and valve body), I might just go the route of swapping the necessary parts from the Lexus tranny to a 340F.  I re-read the thread where Toylexus was having issues with using a 340H tranny, but was wondering if it would be much more straight forward with a 340F? 

On my 4Runner's 340E, I had the valve body upgraded and would really like to use it in either the Lexus 340E or maybe a 340F is the VB's are indeed the same!

Ok, I went ahead and got some 340F tranny parts...



I bought the 4WD output shaft and oil pan.  They're being shipped from Canada so hopefully they'll get here soon!   :)
As soon as they do, I'm gonna swap out the shafts on my Lex 340E and hook up the transfercase!!  Stay tuned...

Just an FYI.  The 4wd Toyota tranny pan has its dipstick tube on the opposite side from the 2wd Lexus.  You may need it as well.

Do you know if there will be clearance issues with the tranny dipstick coming off the right side?  I guess if there are any problems, I could use the Lexus pan instead...  :-\

Ok, I finally finished my output shaft swap!  I decided to go this route since I thought it would be easier than trying to fabricate an adapter.  For those that want to transform the Lexus tranny into 4WD, this is for you!  You basically swap out the rear shafts and essentially turn the Lex tranny into a 340F tranny.  From there you can either mount up a stock 96+ chain-driven transfercase, or maybe a gear-driven case with the help of an Inchworm/Marlin adapter.  Anyway, here

That's not as hard as I was led to believe.  I may opt for that route if I can't get by trans wiring using the standard A340f.

Well I knew I couldn't do this shaft swap without running into at least one problem!  I've just about got the entire tranny back together and realized I have no idea where this piece goes...




So much for keeping things straight! ::)  But I do remember that it came out shortly after pulling the oil pump and input shaft assembly.  I'm pretty sure it's some sort of retainer clip, but I can't seem to match it up to anything in the tranny.  Unfortunately, the FSM I have is for the Supra 340E and the clip isn't in the exploded parts diagram.  You guys have any thoughts?

Hey Russell,
First off, welcome to the forum!
Thanks for the link!  Looks like I'll have to wait to get home to check it out though...I'm at work right now and for some reason that website is blocked, yet I can get on UZswap no problem!!   ???

With the band loose, you can now pull out the D&F Clutch.  With it removed, I noticed something that concerned me.  The surface appeared to be damaged...almost as if some bolts had gouged into the surface

Hey russell,
I think this is the same guy over at Lextreme who did this to his truck.  I was gonna go this route with mine, but the output shafts & sensor rotors were too different!

Hey Cebby, did you by chance run across this piece when you pulled apart your 341E/340F trannies?

I didn't get that far into mine, I quit digging once I swapped planetary assemblies.

Mystery solved!  I emailed John over at IPT Transmissions...here's what he had to say:

"As far as the spring in the picture, it is an anti rattle spring for the overdrive clutch (B-0). Fortunately, it is pretty much an unnecessary part that you can toss if you wish. They made these transmissions for about 15 years before they decided to put that spring in."

Sweet!  Now my "Lexus 340F" is officially ready for install!!   ;D
