Speed converters

[Spud73]

Hi, i'am a new member on Pistonheads with a question. I have bought a speed converter/delimiter for my Skyline and after i installed it in the back of the speedo it seems to play havoc with the auto gearbox. Does anyone have any ideas? Great site by the way and having read some of your conversations, yes your all mad. So i should fit write in hopefully...

Sounds like its corrupting the signal from what the autobox ecu is expecting to see.
A similar thing occurs with MR2's but in their case it screws up the power assistance on the steering.
Specailist required i think...Abbey Motorsport maybe?
