Block Heater & Temp Gauges
Hey Guys,
You may remember a question this past spring about the rise in temp on the
Trans gauge before the engine temp gauge started to move. Someone stated
back then the trans gauge was sensing ambient temp. While over the last week
or so we have been at freezing or below here in Michigan so yes I have been pluging in the big Truck. The first thing I noticed about two blocks from the house was the trans guage moving already and the engine temp was still cold
not ready to move yet. I would think the trans would warm up only after driving awhile and the engine would at normal range, then the trans would warm up.
But that was not what happened, the trans gauge moved first I'm confused?

Are you referring to the stock "trans temp" gauge or a real aftermarket gauge? The stock "gauge" is nothing more than an idiot light... it moves regardless of temperature. Sit it in the driveway and let it idle, and it'll show the transmission quickly moving to the normal range. To make things worse, the transmission will be cooked before the thing ever indicates a problem.

From a Warranty aspect it makes no sense to have a gauge on a piece of equipment costing over $40.000 dollars that is not accurate or user friendly.
I guess thats why Ford stock is so low, They have had to buy new engines and Transmissions for folks.

From a warranty point of view, a warranty claim can't be denied because the temp gauge went up - the operator should have seen it.
A trans temp gauge would have been something mentioned by a few people at a focus group, so marketing decide that its a necessity.
Now when the "trans temp" requirement makes it to engineering, it is thier task to find the cheapest effective solution.
There was no requirement as to resolution or accuracy of the gauge by the customers in the focus group, so quite often the cheapest solution won't be the most accurate.
You also have to remember these are analogue gauges being fed a digital signal too..
Therefore its progression won't be linear.
