Auto-Transmision woes 80 Series 1990 Model

[Hilton Thomas]

Hi All

I recently bought my first Landcruiser. 80 Series vx 1990 model.

My problem was the transmission. When it was cold I had to manually select 1st and 2nd. I then blew the from gearbox seal on the pump.I had some guys remove the box and they replaced various parts. At the end I had to get another torque converter as well. Anyway back on the road but with faults.

First they did not connect the kick down cable and say the box does not function properly with it connected.
Second problem is when it's cold I have to rev to move forward or reverse. This all goes away when hot and she runs well.
Third problem is when she changes from 2-3 there is a slight pick up in revs before she takes.

Can anyone advise me as to what to check?

Firstly the level and condition of the auto transmission fluid, should be a nice pinky red, smell it as well, if it smells like burnt toast start digging deep in your pocket !!!!!

As its the early autobox I don't think it has an ECU controlling it, if so the kick down cable is very important. I had a kick down cable fail in the wide open throttle position, on one of my other auto 4wds. This made the gearbox hold the gear and make the engine rev hard before changing up, all the time. When I took it to a friends auto transsmission workshop he told me that it was better to fail with a wide open throtte, than no throttle input, as the wide open throttle meant that the auto gearbox applied a good strong clamping force on the clutch packs, with no throttle input there would have been little clamping force and the box would have slipped, causing wear and possible failure. Seeing as I was in Belgium when the kick down cable failed, I was pleased I hadn't suffered any damage to the auto box by driving all the way home.

New kick down cable fitted and the vehicle was restored to normal service with no adverse affects. This was over three years ago.

My concern is that if your experiencing slip at low speed, you could be damaging the clutch packs through lack of clamping pressure. If the auto box can't tell what your doing with the throttle pedal, it doesn't know what forces to apply.

It does sounds like you have a few problems with your box, which may not have been helped by a garage which don't seem to be able to fix cars. I'd stop driving it and get the box seen to by a specialist.
