Hello
I have been researching but can't find any solid information on where is the transmission control module on an LR3 and don't mean the transfer case control module behind the battery i already changed that. Some people on the internet say its under the drivers seat and others say its on the tranny. I have an error code U0101-87 and i need to check my TCM. Any solid information would be aprecciated.

Thanks

 

It is attached to the valve body. #13 in this picture:

 

According to Mitchell 1 DIY's wiring diagram, the ground for the TCM at the Left A Pillar. I believe that is behind the driver's side front inner fender. I know there's a ground post or two in there. That might be a good place to start troubleshooting.

 

OK, not in the fender... Here it is in the "A" Pillar:

 

As per the above diagrams its inside the transmission, U codes are only communication errors but does it come back after clearing ? Any other dash messages or trans related error codes ?

 

A leaking Mechatronic sleeve can allegedly cause issues. Is that sleeve new, old or leaking? Its the main connector to the transmission. A part very often replaced with an updated design.

 

Thanks, its a little bit more involved than i though, but i need to do a tranny service anyway

 

Thanks for the info, ive been super busy havne't had time to mess with the Disco but ill look into those diagrams. Thanks a lot for responding

 

It is leaking a little bit, i have to do a tranny service anyways so i guess ill pay once and cry once with this one

 

Hi guys,

I've just seen this post and I have a follow up question. My 2008 Disco 3 has just "died". It doesn't start and mechanics say it is the Transmission Control Module (TCM) that needs to be replaced. They ask for 8,000 bucks which is a lot of money so I am trying to find that part elsewhere. Does anybody know what is the serial number OEM of that part?

Thank you so much
