I have a 95 with only 47k original miles. I've had it for about 30k of those miles and bought it from the original owner. As far as I know the transmission fluid has never been changed. The fluid is reddish brown and I get a shudder around 30-35mph but only when going up hills. I have read all about torque converter shudder and switching to mercon V. My question is, do you guys think it is safe to replace all the trans fluid, from pan and converter? And should I do it? Some people have told me not to drain fluid because then the trans might slip. Any info would help. Thanks.
