Transmission Slip

Maintenance/Repairs

I own a 1998 Oldsmobile Intrigue, also known as a P.O.S. I have owned the car since May and ever since I owned the vehicle after about 25 minutes of driving, the car develops a much harder shift when shifting into any gear. I took the car to both my general repair mechanic and a transmission specialty shop and both said that the car is fine and to ignore the hard shift. When I bought the car in May, it came with a re-built transmission. The hard shift has gone away, however, a much more concerning problem has arisen this past month. I did all of the obvious things, I checked the fluid, it’s fine, full and not discolored. Now, at highway speeds(55mph and over) when climbing a slight hill, the car feels like it comes out of gear (at the point when I fell it should be shifting into overdrive) and tries to shift (I assume it’s trying to downshift for more power going up a hill) but then slams back into gear. This whole sequence of events occurs in about a second. I feel a jarring feeling in the driver’s seat. It feels like the transmission wants to shift, but can’t, or that it’s slipping. The car shifts perfectly at low speeds, but any highway speed going up any sort of hill and I get the problem. I again took it to a transmission shop and they scanned it and said it was the valve body. I don’t know what this means. I added a half bottle of Trans-Tune by SeaFoam to the transmission and the problem went away for 2 weeks. What is causing this???How much will it cost to fix? Is the car reliable even though this problem exists? Will the transmission fail on me while I’m on the highway. I’ve done some research and some possibilities for this car seem to be the Pressure Control Solenoid or the torque convertor, although I was told the TC was replaced when the tranny was re-built. Why did the problem go away for 2 weeks after I added the trans-tune? I can’t afford another car, I am a poor college student. Any help/suggestions would be greatly appreciated. The car still shifts fine, at highway speeds I get that 'slip" though. Thanks!!!
