Hi, I've got an r33 auto transmission. I just noticed last week that when I have the gear in D mode, the light in the dash doesn't lit up at all? The others P R N 1 2 all. lit. up perfectly.. jst the D? I doubt it has an individual bulb for that? any ideas? Haven't pulled cluster out yet

Well your certainly not going to fix it with the cluster in.

Just pull it out and have a look. I dare say it will have an individual globe. To me the trans ECU would get a signal from the gear selector then output a signal to the corresponding globe on the dash

I will pull it out on the weekend but I was jst googling diagrams on it and it seems not to have an individual bulb for it. I just didn't wanna pull everything apart n then find out its nothing to do with the cluster that's all. If it's definitely a bulb issue then I would pull it apart. so far I've google a diagram for it and it doesn't seem like it has an individualbulb for it

guess like u say.. only way to find out is pull it apart!

Having a bit of a look into the wiring diagrams I have, and on FAST, it does look like a bit of an odd setup. I'd pull it out and have a look. It must send some sort of signal to the dash from the A/T controller so I'd say its either a bulb (if they run 1 bulb per gear displayed) or an open circuit/broken wire to the dash

Again, its a strange setup so I may be wrong, but thats where I'd start

Thanks. for that diagram, it'll definitely help when I get a mechanic mate of mine to check it out. If he knows, lol.

I pulled the cluster out today.. and there isn't an individual bulb for it, I took all bulbs out n in to test.. so maybe it's some wiring on a circuit or something sort.

I looked on FAST and it looks like it may be a printed circuit board. Not at my computer right now so cant put the parts breakdown up but you may find that it runs a printed circuit board with LED's built into it then a lense plate over the top

Good news however is that the printed circuit board part is only $66 (US) from Amayama so if you are really keen to fix it then it shouldn't cost too much assuming it comes out of the dash easy enough

Really? I have a stagea but the cluster should be very similar. Theres a bulb for every shifter position. Otherwise how would it light?

The plastic knobs on the back of the cluster are T5 bulb holders.

Its an opportunity to change them all to LED if you so desire (white light makes the dials blue, due to a filter inside the cluster)

Just dont put an LED in the low fuel light.

Thanks! That helped a lot! Think it'll be a lot cheaper jst getting a 2nd hand cluster :) So far it's not really bothering me.. but if i do get annoyed with it and come across a good and cheap cluster, i might change it around :)

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
