Tranny Problem
Hi all
I’m new here, I have a 2000 Bonneville with the 3800 NA and I believe the 4T65-E transmission car has 136,000 km. The problem I am having is the car accelerates very slow in forward gears, The engine is revving up at around 1800 to 2200 rpm then starts to move. Reverse gear works just fine. I am also getting a code P1860. The fluid is nice and red and topped up. The car has sat for about 3 years in a garage. Any help would be greatly appreciated.
