A343F Transmission Rebuild Dilemma (3 Viewers)

[Malleus]

Thanks everyone. My new steel plates and clutches are from the Transtar kit. Since this pack consists of 7 steel plates and 7 clutches, a tiny thickness variation might easily explain why my gap came in a bit large. I still have all of them so I could make those measurements to check that. However, things are not quite so clear cut.

The FSM and various parts diagrams such as, EPCdata, are not always in agreement with each other or reality. This situation we are discussing here is a good example of that. On page AT-59 of the FSM, there is a nice drawing for this first & reverse brake pack. The problem is, the drawing does not match what was in my transmission. That drawing shows 8 plates and 7 discs/clutches in the Land Cruiser pack. Mine had 7 of each. I watched a decent video of an A343F rebuild and that transmission also had 7 of each. If you look at the EPCdata drawing, it shows 7 plates and 7 discs/clutches, which matches number-wise, but the order they show is not correct.

My Transtar kit had 7 plates and 7 discs/clutches, which agreed with what I removed, and so that is what I replaced in mine. But, when I discovered that the gap was a bit too much, I will add back 1 plate taken from my old plates. Doing that, I will get the gap right in the middle of where it should be. So, funny enough, when I am done, I will have 1 flange, 8 plates, and 7 discs/clutches, which matches the FSM...

The only remaining question is where to place it. My plan was to add that extra plate directly on top of the flange, creating a thicker flange. But oddly, the FSM shows that 8th plate going in at the top of the pack. In effect there are 2 plates back-to-back at the top. SO I will need to think about that.

As long as you don't put two clutch plates back to back, it doesn't matter where you put the extra steel. It's just taking up the gap between the clutches and the piston/spring retainer.

I thought the hardest part was that ?!?!?!%%@@ snap ring at the bottom on the Number 2 brake piston. I almost needed a bigger sledgehammer for that job.

Two very long, very large screwdrivers

Which A343F manual are you using? There are two and they are both for Land Cruisers, but they are for the 80 and 100 series versions. The two transmissions are not the same.

The copy I have has AT147-01 on the top in miniscule print. I will have to look further.

Yeah, that is where I finally arrived, but I had to step away twice for a break to get there.

Paper or PDF?
You want RM479U.

It is a PDF that I got from this site as I remember. I do not see any reference for RM479U.

I went through my PDFs and there is one listed as RM479U, but that PDF shows how to remove the transmission and how to diagnose codes and so on. At least that is what is in my PDF stored under the RM479U file name.

I am grateful that I have 2 spare A343F transmissions so I don't have to rebuild 1

That's the one I posted. I need to replace it with a copy that has the pub number on it. You are using the correct version.
