I had my '02 transmission fluid and filter changed (at the dealer) in in Feb. Last couple of weeks it has been starting to shutter when taking off from a stop just before it shifts out of first gear. Sometimes it actually feels like I am hitting patches of ice. I decide I would check fluid level and due to having no dipstick I followed the instructions stamped on the bottom of the pan. "outer bolt for fluid drain center bolt for fluid level check - check fluid level by removing center bolt until fluid stops running out then fill through fill plug until fluid begins to run out again" (I don't know if this is the exact wording) Anyway, with the vehicle level I removed the center plug out of the drain plug on the bottom of the pan and fluid ran out of the hole. I put the plug back in after about a quart ran out (it looked like it wasn't going to stop) because I though that I might be checking it wrong. Because of what was stamped on the pan I thought that I would see a little fluid come out not that much. Does anyone know the proper method? Is my transmission overfilled?
P.S. 46,000 miles and problem seems to get worse as transmission gets warmed up. It is hardly noticeable when cold
