  1. It does seem really strange as there seems to be very few issues with the IPS gearbox beyond the connector/plug. I'm sure mine when we first had issues a few years back spat out a code relating to one on the internal sensors, presumably the same one as I can only see that one on the parts diagram. I suspect mine only lasted as long as it did as it's kept in a dry garage most of the time. If you've seen the pictures of my plug on the other thread, I'm surprised it lasted as long as it did.

  2. Well ive just had the connector in the gearbox replaced and the pins on the loom. I believe they pins took longer than expected and they didnt remove the gear selector that Im aware of but my invoice was just over half of what youre suggesting. They have 8 hours labour against it and thats a main dealer. So they had to drop the valve block and replace the gearbox oil etc so in theory that leaves them 2 days to do the extra beyond that for the selector and speed sensor. Just looking at the parts diagram, my part was no21 the speed sensor is no22. Looking at the article on page 10 of this:-

    Then it looks like it just bolts/clips onto the valve body asssembley?

  3. I dont know but it will involve presumabley taking the sump off and dropping the valve body assembly, so a gearbox oil change at a minimum. Do i presume you are getting an error code indicating the sensor is faulty? I ask, as a couple of years ago I had some issues which eventually cleared, the code was read and it did relate to one of the gearbox sensors. Fast forward to this year and it was found to have corrosion on the gearbox connector. That needs a new connector for the gearbox side and normally an engine loom.  The garage has re-pinned mine, I presume as a bit of an exercise, so its cost a lot less than replacing the engine loom, but dont know if it would actually be viable for them tbh.

  4. Well the GTE's were rebuilt from the end of 2014 onwards so they should be ok too, obviously not. Ive found out the Toyota TCU plugs in the gearbox directly and is bolted to it, lotus have it mounted in the car. It makes me wonder if its more an IP rating issue of the loom plug compared to the Toyota TCU. Heres the state of mine. I think a $hit load of dialectric grease is inorder for when it goes back together.

  5. Started off as likely AC condenser replacement, which then transpired to corroded AC and oil pipes in the sill, then just as that was done the gearbox started playing up. It did it one before a couple of years ago then cleared. It's turned out to be bad corrosion on the gearbox connector. That in itself isn't the end of the world, however the plug on the loom is, the only official remedy is a new engine loom!

  6. Mines been in for other works and having this issue. The plug on the gearbox has corroded, this is reasonably priced and straight forward to replace. The socket on the other hand is part of the engine loom and that isn't cheap. They have to pull a few bits to get to it but it's obvious when they do. I'm struggling to find any other options at the moment.

  7. You can pull the wheel, take th wheeel arch iner off, unbolt the oil cooler frame (if you have one) and gentle move it out of the way, then you need to unbolt the tank as its on the side of the tank against the chassis. Also make sure you get the rubber grommets. Dont know how much it is from lotus but as usual its off something random, I want to say either an mg or a blck cab, but cant remember as it was years ago now.
