my auto tranny went out at 35k miles, would hesitate shifting from 3rd to 4th, took it in and was replaced under warranty, i guess i was just one of the unlucky ones
New transmission replaced under warranty sounds rather lucky to me! It's unlucky when the warranty is gone or they say nada to the replacement claim. You should be real good with your new trany, they don't rebuild them they replace them.
My experience with Toyota auto transmissions is very positive, going back to the A440F auto tranny in my 1991 FJ80. I have never had a failure or a problem with one, and I put 250,000 miles on the FJ80, 100,000 miles on a Sequoia, and currently have more than 120,000 miles on my auto-tranny FJC. But auto trannies are more complex, and have more moving parts to fail than a manual gear box. IMO it's important to fully flush the ATF in an auto tranny more frequently than the recommended service interval, if you use your truck off-road or tow with it. And to use synthetic ATF. There are a few people here on the forum that have had problems with theirs; the vast majority have not. IMO Toyota and Honda both build an auto tranny as well or better than anyone.
The grinding you describe was almost certainly in your transfer case though, not your transmission. The VF2A transfer case on your truck is very robust mechanically. The shifting sensor switches on it the various ECM's use seem somewhat problematic for some folks, but mechanical failures of the transfer case itself are extremely rare.
I hope not the A440F was/is the largest trany Toyota ever brought into the US. They used that same trany in their diesel buses in Japan. (look like airport buses) Of course the 3FE motor could never over power that trany! The most anemic motor put into a Land Crusier in that package! We know of one FJ80 that was re-powerd with a 24 Valve Cummins and they used the A440F! The trany lasted for almost a year behind that power! (then died a horrible death)
Thanks for the idea. With the rig stopped and AT at N, I will try moving the transfer case stick, firmly and quickly, when going from L4-N-H4-H2. I was reading elsewhere (here in the forum), that when trying to go from L4 back to H2, that if it is not easy (e.g. grinding) then move the truck forwards and/or backwards a little, to realign the gears--then retry. I will try this also. I followed the operator's manual carefully, it makes no mention of these issues. It seems maybe TOYOTA should spell these solutions out in the manual.
In any case, I just love my FJ, and hope this matter with the transfer case is solvable
with my improved technique. Thanks for your suggestions.
Auto trany + putting the t-case in N the case stops spinning. Its going to grind if you move it slow or hunt for the gear. Like 1911 said, authority!
I have 191,***+ on my 97' FZJ80 Land Cruiser, shifts strong and no issues.
