So is the A440F a 4 or 5 speed?

Only full hydrolic a44?f that I've heard of in the world that has full lockup control is longbow's period,and it gentleman is electrically operated.
Sure it can, with the right valve body. The valve body on the 440 just isn't equipped to do so without heavy modifications. 'wrongway around' wants an easy solution, or so I assume, which is simply not possible.
Dang Lane, I used to be helpful like you; now I'm just old and crotchety.
And I don't even have my 80 anymore! You're slacking, Curtis!

sorry i don't know how to link,i can barely search on the computer as you can probably tell by my spelling and english. Doesn't everybody want the easy solution. Can't say it can't be done at least anymore. I'm just wondering if it can be done with a stock v/b. Lka1988 did i miss the answer to the question of what does control the lockup solenoid, where does the electrical side of things come into play. kind of wanting to know if you can over-ride the solinoid like everyone does on the electronic transmissions with a button which basically splits your gears. Please dont think that this is just for me ,i'm sure this mod is going to be a must have just like the power rod ,intake mod ,gturbo , 9 pin mod is to all the 1hdt diesel guys,let alone any body with a a44? with cc.
Of course everybody wants the easy solution. But that doesn't mean it's suddenly possible.
In short...No. Not without heavy modifications.
Ok, you're getting two things mixed up here.
1) Torque converter lockup
2) Overdrive solenoid
These two functions/components are not related in any way other than being in the same transmission.
The lockup control for the torque converter is housed deep inside a transmission component called the valve body. It's basically a housing for a maze of tiny oil passages, one-way ball valves, and valves resembling solenoids. Now, as I stated 4.5 years ago, the electronics only come into play when the cruise control needs to accelerate. All it does is *deactivate* the O/D solenoid, causing it to downshift into 3rd gear. That's it. I promise.
This mod IS a must-have, but only for those who have fat wallets. The modified valve body (I forget prices, but it's not cheap) is shipped from Australia. The shipping also costs lots of money.
Since I'm in here, I might as well finish this thought.
As I stated in the previous post, all the electric O/D solenoid does is act as a secondary actuator for the 3-4 shift valve. That's it. Hydraulic pressure still actuates it, that's how the non-CC A440F works and how the CC-equipped A440F can still shift into O/D with the thing unplugged.
this heavily modded v/b that you keep referring to is nothing like im talking about. the only one you seem to know of only locks up in 3-4 gears.and yes you are correct that one comes from aus.(wholesale automatics). can you explain how this one can get lockup in each gear. pretty hard to move forward like this glad longbow never read this thread before.

AFAIK to get the torque converter to lock up in each gear would require massive modification to the A440F valve body to tell the fluid to lock the converter when you want it to.
The hydraulic circuits are a lot like electrical circuits. When things happen, fluid pressure makes other things happen. In order to take control, you have to send fluid to certain parts of the VB. Much easier to do with one that has electronic valves instead of hydraulics because electricity is much easier and cleaner to control and customize.

My setup is a stock A440 out of a FJ80 that has had the VB fairly modified with a different solenoid that allows lock up at any time with the push of a button. The stock CC solenoid is only used by the CC to drop it down out of OD if needed for a hill/headwind. Mine is no longer hooked up.
I have not fully tested mine yet as I am still in the final process of the swap.

yes it is easy on the electric solenoid transmissions ,one electric solenoid for lockup = one wire . funny everyone seems to be stuck on the v/b needing to be heavily modified for tons of pressure yet on the electric one all that needs to be done is to activate that lockup solenoid . I guess i just cant get it that in principle that it's just a solenoid that controls lockup . and in reality you only need to control it just like the electric one. i thought maybe re-opening up this thread that more might had been learned . Sorry you guys are obviously getting angry ,so out of respect only i'll stop . plus i just realized that there is very few 80's with this transmission anyways so knowledge might be limited . But i will repost when i get the answer. till then keep helping others gentleman.
Ok. Stop right here.
Clearly you're not understanding what I was trying to explain to you in several previous posts.
Yes, electronically-controlled transmissions are easier to modify for a push-button torque converter lockup, but the A440F is NOT an electronic transmission. What wheelingnoob has done is modify (or purchase a modified) valve body that has provisions for an electric solenoid IN PLACE OF the normally hydraulic valve that controls torque converter lockup, among other things I would imagine.
What you are not understanding is that this is NOT a simple job, it is NOT plug-and-play. It requires professional expertise and a massive amount of patience to modify the valve body properly. If you fudge it up, you're out a LOT of dough. And believe me, VB's are VERY EASY to fudge up.
If you have the money, cool. Go ahead and modify it to your liking and make it do what you want to do. I (we?) have no problem with that. What I DO have a problem with is your argumentative attitude and unwillingness to acknowledge what I've been trying to explain to you. Wheelingnoob HIMSELF posted:
Typically, that means extensive modifications were required. Take that for what you will. I'm not trying to dissuade you from doing what you want, but it seems that you just aren't hearing what you want to hear.

the deal is just about to become public,shouldn't be much longer,im waiting to here if it will work on the a442f(full hydrolic ), and wether or not you need the reworked the v/b . i really don't think you need the higher pressure for lockup, that most think you do if you see what others have actually done to overide the solenoid for lockup, being pressure is already there activateing a solenoid for lockup already, mind you i don't even consider myself a backyard mechanic let alone someone that is specailized in transmissions. as soon as i hear or find a solution i'll post up here and give you a personal pm.cjf
only the electric solenoids can be activated manually i meant . this is the first a44? full hydro iv'e heard of being converted to manual v/b . and ya i hear you on the pm thing . hope it's not going to be to expensive.
