Hi everybody,
My trans temp seems to be running high; 1st linefrom bottom to halfway past the 2nd line, whatever temp values they represent. I seem to remember the needle always resting on the bottom with the exception of extended idling times. Whenever I pull my trailer, it would only get to that first line. i don't know if it is a coincidence since I'm now in the Gulf Coast region, but I'm concerned about overheating when trailering.

I had my cluster rebuilt. My tach and oil pressure started going haywire just recently. I was hoping they were all related. The other guages are reading fine now but the trans tremp is still different.

One idea I have is possibly replacing the trans cooler with a larger one. does anybody have any experiences and/or recommendations?

Thaks folks!
