This is the sort of transmission temperature gauge kit available in the US:
http://www.ipmart.com/main/product/B...php?prod=55809
Amazon.com do it for about $48, but won't ship it to the UK.
This kit would therefore cost around £65 to deliver to your door (although a group buy on this could be beneficial in terms of carriage...).
It seems to have everything, and includes a thermostat so that the cooler is effectively bypassed until the atf reaches 80C. Unfortunately (well, maybe not for some
), the gauge only reads in Fahrenheit, although I don't see why you couldn't install a different gauge with this kit.
I just haven't found an installation kit anywhere else!
Steve - what sort of size cooler do you think would be best for behind the foglight grill, and how would you mount it? I'm still tempted to install the cooler in front of the rad, as per Dave's article.
