I installed the sending unit in the hard line just before the cooler. I understand and accept that this may give me higher readings than the pan, but I'm okay with that. As Stutaeng said, I'll be mindful that it may be reading higher than if in the pan. The whole point of installing the gauge is too pull over and let things cool if, while towing, the temp starts climbing too high. The problem I've having is the cheap-ass gauge I bought is reading too high and it doesn't have a zero set for the needle (when off it does not return to zero but rests on the 60 degree mark). I ordered a new, better gauge. Supercharged111, are you saying there is a temp sending unit in the transmission pan? I can't find it if there is supposed to be one. Being a 92 and OBDI, I'm doubtful of that.
Eric, the Awful, being a K2500HD, I have the larger front disks and larger rear drums. I just rebuilt the drums and installed new rotors and pads on the front. I deleted the rear ABS sensor and installed a larger model master cylinder (from a 2003). Brakes work so much better than before.
Supercharged111, regarding your question about the torque converter staying locked up, I always have troubled determining that, especially where I live since I'm rarely on a flat road - there's always a grade. However, it seems to be fine. I can see by the tach it holds pretty steady unless I'm accelerating. I think some of your comments are leading me to believe you have an OBDII, especially if you're reading it from a laptop. I can't do that with an OBDI truck.
Appreciate all the comments and help.
