how do you open the TCM?

Can anyone please tell me how to open the TCM that I have removed from my 2001 S430? I want to see if there is any corrosion and give it a clean with electrical contact cleaner as recommended by some of the more experienced guys on this forum. Is there a method of pulling it out of the black plastic sleeve? Many thanks in advance.

Please use a small flat screw driver to pry it open.

Thanks.

Thanks for the reply. I have tried a number of flat screwdrivers and other such tools but it seems to be very tight and I don't want to break anything. Is there a trick to this?

No, no trick is needed. Just simple and I don't even remember how I did it.

I don't think you can break anything. The circuit board is sandwiched between the two halves of the case. It is not easy to damaged even you break the plastic case/cover.

Good luck.

It's actually very easy to open, you'll need 2 flat screw drivers one for each side. There are clips on each side that need to be released. I've opened mine with ease but come to find out my TCM was corroded so i ended buying another one from a salvage yard for $200 and thank goodness its been working great otherwise i'd have to pay $1300 for a new one.
