1995 Cadillac El Dorado Transmission Slipping

[quote:e4fc180074="RonWohlfarth"]Transmission problem
1995 Cadillac El Dorado V8 Two Wheel Drive Automatic 189000 miles
----------------------------------------------------------------
After running car for 30 to 45 minutes at various speeds (30 to 65) all is fine and THEN-- when going from 40 to 65 miles per hour the motor continues to race at 4,000 to 4,500 rpm's...It will not settle down to a normal drive rpm of about 1,500 to 2,000...
Is there an additive that may help..
A few weeks ago dropped trasmission pan replaced both filters and put new fluid in...
Looking forward to your response...
Thanks
