So is the A440F a 4 or 5 speed?

Whose is it?

Yours?

Someone else's who's a member here?

Where are they having the work done?



I mean really: Is this all top secret or something?

Relax man, its being tested. Its working on one A440 and in mine waiting testing. Once its been fully tested the information along with a thread will be made. This is not my work/idea or reserch im simply a beta tester. The one that has come up with this is a mud member and knows his stuff when it comes the the A440. I hope to have the testing done on mine by end of August.

Again this is only for the A440 and possibly the hydrolic A442.

We could be approaching this wrong. Perhaps the OD actuator from the CC circuit disengages OD when it feels it needs the transmission to downshift. That makes far more sense than it enabling OD.

So I just realized I know exactly how the CC solenoid functions. I'll bet others have experienced this as well:

Suppose you're on the hiway and start heading up a grade with the CC engaged. If you try it a few times with/without the CC engaged, you'll notice that the tranny kicks down to 3rd at about the same point whether or not the CC is engaged. However, what is markedly different is when the tranny chooses to upshift back to 4th. With the CC engaged, you have to crest the grade and be heading down the other side for a good 5-10 seconds (annoyingly long, actually) before the tranny upshifts to 4th. On the other hand, if you crest the grade either without CC engaged, or disengage it once you crest it, the tranny immediately upshifts.

So in short, the solenoid doesn't *shift* the tranny into 3rd, rather its function is to *keep* the tranny in 3rd once it has downshifted on its own, presumeably so it's not hunting between 3rd and 4th all the way up the grade. Then the solenoid only allows the tranny back into 4th once it's *really* sure 3rd is no longer needed.

Updates?
 
Glad to hear they worked great. Thanks for your feedback.
What were the mods?
Do you have info on how we can replicate them?
Inquiring minds want to know. :)

To followup on this, the CC solenoid wire on my old 91 has been disconnected for several years. There is absolutely no change in functionality of the transmission or Cruise control. Everything still works, it downshifts when it should, the TC locks/unlocks at the same speed it always has.
Not sure what you guys are arguing about, but please continue.

Either it's your imagination or it's in third and shifting to 4th and immediately locking.

The A440f is a 4 speed transmission. I seriously doubt yours has been swapped, and even if it has it would have been a huge, major and noticible thing with tons of unique parts, electronic controls etc.

The beauty of the A440f is that it is hydraulically controlled with no electronics at all. It's a very robust tranny if taken care of.

Explain "If taken care of" beyond changing the oil?
