Newbie here, making my first post (I've read all the transmission threads I could find on the forum, but none seem to match my problem, and neither new fluid nor a kick-down cable adjustment have helped so far).

I just bought a 91 fj80 from a buddy for $500 less than kbb. He was trying to flip it, so he didn't know much about the history. I've had a major gear lust for a Land Cruiser since I was about 14, so this seemed like the right opportunity to get into one.

The Cruiser was a B title (mileage in addition to what's on the clock) with the odometer showing 159,000. I took it to two different mechanics who pointed out several leaks, a non-original tranny, and the looks of being driven over 200k miles, but otherwise the engine still sounded strong.

I noticed the transmission sticking once or twice while test driving it, but honestly wanted to buy it so bad, I tried not to notice it. After buying it, I have figured out a definite pattern and tried to remedy it without success. So now I'm asking for more help.

Here's the pattern:
The transmission will not shift into 2nd gear until I get over 3,000 rpm (sometimes almost 4,000) the first time after it has been put in Drive. It only sticks the first time, and it only sticks between 1st and 2nd gear. It shifts smooth with all other gears, and after it has made the primary shift to 2nd, all subsequent shifts from 1st to 2nd happen around 1,500-1,800 rpm - until I take it out of drive and put it back again, then the process starts all over again.

It doesn't necessarily have that much to do with the car heating up. Once or twice it has made the shift to second when cold, but almost always it's a hard shift to 2nd gear - just the first time - even if the car has been running for a half hour.

I had a mechanic (from the Toyota dealership) pull the pan, clean out all the crap, and fill with new fluid - didn't help. I have adjusted the kick down cable a mm or so in either direction and this hasn't helped. Loosening the cable seemed to make it slip in other gears, tightening seems to pull the throttle cable and make it run 30 mph without my foot on the gas (slight exaggeration).


I am now thinking that I got in over my head on this purchase, especially considering that I'm not exactly the Car Whisperer or anything like that. Here are my two thoughts:

1.) Could it help to replace the kick-down & throttle cables? I run a bicycle shop in downtown Phoenix, and when I see brake or shifter cables this old, I almost always recommend to replace them. The plastic housing is pealing off and they seemed kinked in ways they aren't supposed to be.

2.) Could my non-original tranny be something other than an A440F? A couple guys have told me it sounds like I have a bad transmission solenoid. Everybody on the forum says there are no solenoids on the A440F. So, where do I find a serial number or stamping on the transmission, or how do I figure out if it's not an A440F, and if that is the case, how do I find out what kind of transmission it is?

Any help on this? Thanks in advance...

Wait, almost forgot: :flipoff2:
 
Update:
Drove the cruiser 3 three days ago and popped it in and out of 4-low just for grins and giggles. It still followed the same pattern of not shifting to 2nd gear on only the first occasion after engaging the truck in drive.

I let it sit for three days then drove it today, and every time I have driven it today, it has shifted perfectly.

Can there have been a delayed reaction of new ATF cleaning things out? Or could throwing it into 4L have done anything?
 
Not sure about alot of your questions. If it continues to shift perfectly, then leave it alone, if not read on.

The only experience I had similar in a vehicle was in my 96 Dodge work truck. It had about 300K miles and started doing the same when it began getting cold outside. I had to drive it around the block or two until it decided to shift into 2nd. Yes, RPM's got up there as well. My fix (which worked) was to drain a qt out and add a qt of Lucas Transmission additive. This stuff is really thick and the best way to put it in is to let it drain itself overnight into your fill tube. I added a qt each winter when it started doing it and it lasted 3 years until I sold it with the original tranny and 345K miles.
 
It's not likely to be anything other then an a440 you have. The compliance plate on the firewall will tell you specifically what transmission it is.

The a440 is a full hydraulic transmission, no solenoids.

Your problems sound like a valve body problem. Time for a specialist unless you are keen. With a bit of luck it might just be something simple like the valve body gasket.
 
Another Update:
I think I've figured the pattern out a bit more.

Ultimately, the transmission sticks if I have to drive in reverse to back out of a parking spot, do a 3-point turn, etc.

The transmission will shift perfectly if, after starting the truck, I cycle through all the gears (P to L, then back to D) and then pull forward to leave a parking spot or driveway. It usually sticks if I don't cycle through all the gears first.

Any clues what this might point to (other than I should back into all my parking spots from now on)? :)
 
I’m having the problem too.
1990 HDJ81, hydraulic A440 transmission.

Just moved from OK to MT, and after taking a trip to the mountains the truck doesn’t want to shift from 1st to 2nd.

Got home and I can see a couple ATF leaks (one under power steering pump, looks like bottom banjo bolt, and one from transmission seal), but both are very slight. Not much more than a quarter sized drop every couple days.

Going through some basics (fluids and such) but if anyone else has any further thoughts, I’d be glad to hear them.

I’m a total newbie when it comes to auto mechanics, btw.

Cheers,

Fluids seemed to work for me. Flushed transmission and winterized and it shifts pretty smooth now. Hope this helps.

Did you fix the problem
 
Delay of shifts from 1st to 2nd is most certainly one of the signs of a bad tranny. I had my tranny replaced just over a few months ago, and i was getting delay of 1st to 2nd shifts like you have mentioned before plus some vibration when the car takes off. Fast forward to a few months and many trips later, my tranny finally giving up the ghost. Lost 1st, reverse. I would say check the fluid and see if they are burnt, otherwise, replace fluid, drop the pan and change out the filter and make sure fluid is topped off. Good luck.
 
Hi, I’ve rebuilt mine when this happens,and it’s happened to several of them.
