When I read about this 150 deg. warm-up issue I wondered if my 4EAT temperature sensor could be my problem. I have Legacys and Imprezas that have the lower 50 degree warm-up temperature and I assumed the SVX was the same. Now I find out that the SVX switching point is 150 deg. I want to tap into the sensor lines to the TCU and monitor it with a digital voltmeter. I should be able to determine if it is changing as the transmission warms up. Now, does anyone know the calibration on that sensor? If I had that I could monitor the temperature while driving to determine if the tansmission oil is warming up to a high enough temperature to let the TC engage. Thanks guys - Jim

20*C/68*F = 2.3k to 2.7k ohms. In circuit voltage = 3v to 3.5v. 80*C/176*F = 280 to 360 ohms. In circuit voltage = 1v to 1.3v. The wire that runs between the gearbox and the TCU is a yellow/green wire, that is at the No. 5 pin on the square gearbox plug, to pin 10 on the 12 pin black plug at the TCU. Harvey.

I went the simple route and installed an electric temp gauge in the lines when I added a cooler. I bypassed the factory cooler completely, so on really cold days, the TC doesn't lock at all, even after 30+ minutes of highway driving. Not so great for the gas mileage, but I figure I can always partially cover the cooler if it really bothered me. So far it hasn't, and I am not nearly as concerned about the tranny slipping in summer stop & go traffic. Though if the gas prices keep climbing, I'll start having a piece of cardboard handy.
