Well, looks like my number is up. Over the weekend I started having transmission trouble. My truck is a 1994 FZJ80 with the A442F transmission. Unfortunately, the O/D light is out so I can't get codes from it. Checked engine codes and there aren't any.
Anyway, when I put it in D I get no power...
Two things Y
You need a functional OD light to read the AT cods you use a jumper in the OBD connector and count the blinks
And I used Isuzu solenoids 60$ for the all 4
2x Isuzu 8-97202072-0 Transmission Solenoid

I've been struggling with transmissions issues on the 1994 we bought last year to fix up for our youngest son. Finally figured out it was the Transmission Control Module. Back in September while driving home from work I lost all gears except 2nd. While in Drive with O/D on it would start in...
Hello mudders,
I am working on developing a trans control harness and tune for my 1993 USDM 80 series so I can use a Haltech standalone ECU. I have been able to successfully map A34x series transmissions in Tacomas and for the most part the A442 (AW450-43LE) looks to function the same really...
...move, like it’s in park. My mechanic thought the lock-up solenoid was bad and replaced it, but it didn’t fix the issue. The transmissionsolenoids are all good and there are no chunks of metal in the transmission. Any ideas on what the issue might be? I’m not sure if it’s an electrical issue...
Looking for troubleshooting help. I have a 94 LC with A442F transmission (US specs). All of a sudden it would not engage in Reverse and it will stall if I shift to D 2 or L. When the transmission wire harness is unplugged it will go into gear (I think that puts it into safety mode?). Thought...
It’s the first thing that you should check on a A442F if you’re having shifting issues.
Some Isuzus use the same transmission. The shift Solenoids can be had for a fraction of the cost of the Toyota ones.
If you have trouble find them I can go through my receipts and get you the numbers.
Speedometer bounce is gone. Replaced the speed sensor and not a bounce in a 15 mile test drive. And, a very important side benefit, the transmission hesitation I was also experiencing went away as well. Talked with my Toyota mechanic who indicated that speed sensor signal gets to the...
Long time lurker, first time poster here. I have a '94, non-locker bought it a couple years back. I'm looking to put together either an Elite 2500 or the 2000 to control the engine and transmission for a few reasons. I'd like to be able to tune the 1FZ to understand what the milage potential...
Good morning,
My 1997 FZJ80 has an issue where when I put it into gear it shifts hard and going from first to second it shifts hard. This only happens about 25% of the time. The transmission works great outside of these hard shifts occasionally. I was considering replacing the shift solenoids...
...be that connection.
First thing really is to check the error codes.

Did you replace the bad gasket between the filter and the valve body?
Did this recently start happening with the super cold weather?
Did you use the correct ATF?
Did you check the ATF level with a fully warmed up engine/transmission (20+ minute drive in cold weather)?
May not be your issue...
442 solenoids seem fragile. Some cruisers go through them again and again. If it has a track record for eating shift solenoids that'd be the first thing I check.
