Default Re: Check Engine & Trans fluid questions

Change the t-stat, gauge should be approx in the center at operating temp which is about 100 deg c. t-stat is stuck open not allowing engine to reach operating temp. As far as the trans oil change, some mechanics dont like to do them on high mileage vehicles if its never been done because in rare cases it starts to slip after the fluid change. I think your worse off not changing it myself. I have changed fluid at over 200k at the first change and never had problems.
