car won't move in drive or reverse it drifts

ck the fluid level 1st other than that it may be an internal trans issue

Transmission fluid is full but burned black

sounds like its time for a trans

Towed car to machanic he changed the transmission fluid,cleaned the filter, replaced a blown headlight, fluid is still dark. Been driving the car two days, it is running fine. Thank God!! We will change the fluid again today and relpace the filter. Thank you so much for this wonderful Web-site. You were very helpful.
