tranny hard shifting
My 98 SLE suddenly started hard shifting tonight. Previously was fine?, but now it is really firm going from a stop to 1st and 2nd especially and 3rd. Doesn't slip or anything and drives fine, but at 96000 miles I am worried. I will likely bring it to a local shop on Monday, but I was wondering if anyone else has had this happen and if so, what was the problem. Thanks Jim

Well, the problem is gone this morning so I have to believe that it was a temporary sensor malfunction. If it comes back I will take it to the Pontiac dealer and not the transmission shop.

Hows the fluid Jim? Has it and the fliter been changed lately? Does it smell burned, or have a brown color to it? If it hasn't been changed lately, you may want to do that even if the problem has gone away, for now.

the fluid is sort of orange colored. the level is good, but the filter and fluid have not been changed in 52k miles. At 44k the dealer changed the fluid and filter on a unit that got 100% of the old fluid out, it was supposedly a new thing there. might be time for service again.

Yeah, the color doesn't sound good. I'd suggest at least dropping the pan, and replacing the fluid and filter. While you're in there, check for any chunks or shiny things.

First the fluid should be a reddish pink color... If its a bit oxodised then it may be a reddish with a brown hue...
Next thing is lets keep in mind that the 4T60-E and the 4T65-E( he has ) are controled diffrently..
I believe you may have an issue with Line pressure control, I believe its a Force Motor that may be going bad IIRC....
If you change the fluid and filter and that changes nothing, have the tranny looked at by a reputable shop soon..

Maintaining good clean fluid and filters in the tranny is very good preventive maintenance, however, it will very rarely (dare I say never?) fix a shifting concern that is already existent.
If you change the fluid and filter now, you may be dumping money into a bad tranny. Probably not, as the description you gave of the tranny sounds more like a sensor or something simple, but the possibility is still there that the tranny may be bad.
I would suggest that you have the car checked out to determine what the cause of the hard shifting was before putting money into the tranny.
