Hi all, I hope someone can offer me some advice on the problem I have. I recently purchased a 2001 (mk2.5) MX5 1.8 automatic however the speedo does not work currently and the gearbox does not change gears on its own - it has to be selected manually from 1>2>3. I am guessing that this issue is linked if the gearbox works off the speed the car is doing.
I have so far taken it to two garages, one being an MX5 specialist however they have not been able to fix it even after looking at it for several days. It also seems like this is an uncommon issue as I can’t find any information online and I have even asked a couple of MX5 breakers but they don’t know what controls the speed on these.
Any suggestions would be very much appreciated as I don’t know what else to do. The specialist I took it to said that it would probably need a whole new gearbox because they think that a sensor inside the gbox itself is likely in need of replacement on my car.
