stuck Posted March 4, 2009 Share Posted March 4, 2009 Hi all, Since buying my '88 3.5 Efi auto I wondered why I had no reverse lights, wasn't top of my list but at the weekend I got around to whipping the lens covers off to find that the lamps had been removed. Reason this has been done is that there is a permanent 12V at the lamp holder, I'm assuming there is some kind of (proximity?) switch somewhere on the box, my Haynes is a bit vague on this subject but I think I have to take out the trany tunnel to get at it, is this correct? If so how big a job is it and can anybody give me a part number for the switch before I pull it apart? Mant thanks, Mick. Quote Link to comment Share on other sites More sharing options...

I think you have to work up the side of the box from below. The switch is both reverse and start inhibit and on mine is RTC4937. If you Google that part number you will see what it looks like. At about £60 you may decide not to bother with reverse lights. Steve Quote Link to comment Share on other sites More sharing options...

stuck Posted March 5, 2009 Author Share Posted March 5, 2009 I think you do hence the question. I love getting covered in mud though so not a problem for me Quote Link to comment Share on other sites More sharing options...
paintman Posted March 6, 2009 Share Posted March 6, 2009 I think you do hence the question. Not part of the MoT so doesn't matter. Mine's an 86 & the tunnel is welded in. Quote Link to comment Share on other sites More sharing options...
steve_d Posted March 6, 2009 Share Posted March 6, 2009 Not tried to do it but looking at the parts catalogue the switch lives just above the joint between main case and sump so only about half way up the box. It also appears to be held in place with a plate and one fixing. Steve Quote Link to comment Share on other sites More sharing options...

If you're lucky you might be able to pull the switch out far enough to clean it up & free it off in situ. Colin. Quote Link to comment Share on other sites More sharing options...

clbarclay Posted March 6, 2009 Share Posted March 6, 2009 On the 1987 RRCs at home ther bulk of the transmission tunnel is welded, but on the top around the gear sticks there is a pop rivited in section. With this removed you get some access to the gearbox from above, but not much (enough to get an arm through) and you have to remove quite a bit of trim to get to it.
