Hi guys.
I have just replaced the auto in my EL.The original one would not hold 4th - it would change back to 3rd as soon as any power was applied. I was told by the local auto place the the entire trans needed rebuilding, so I decided to get one 2nd hand from the wreckers.
I have now fitted the second hand box and it only has 1st and reverse.
I have made sure there is enough fluid and the right type.
All the wire connections at the trans are done, but I also have no speedo.
Does this sound like something easy to fix or am I going to spend next weekend changing another box?

Thanks
Andrew

Looks like next weekend you might be doing it all over again...have you thought about a manuel conversion

I thought about putting a 5 speed out of an XF in it - I have one sitting out the back. I would still have to get an adaptor plate for that and the extra pedal etc for the EL.
I hate changing gearboxes ^%#@(*! wreckers.

Thanks

Sounds like you "inhibitor switch" is knackered.....mine done it to, for the life of me coudlnt figure it out, drove home sittin on about 2k revs and a total of about 50km\h.

The inhibitor switch controls the shifts I beleive. But it fixed mine when I put an AU switch in it. They are exactly the same. Or your wires to the switch are loose.

Not sure which one the inhibitor switch is , but I talked to a bloke I know at an auto place today. He thinks it is because of the speedo not working. I am going to switch the speedo drive with the old one (which worked) and see how it goes then. Apparently the ECU goes by what speed you are doing to upshift

thats right
