general problems of the 1998 Volvo V70

I just purchased about 2 months ago a 1998 Volvo V70 used on 4/3/2014 for 3000. 00 . The vehicle drove just fine up until two weeks ago where the transmission seems to be slipping. While I was riding on i695 and was going about sixty miles per hour when the car jerked and cut off, meaning blinking in and out of the electrical system along with the engine as I was pulling over on the shoulder, which is terribly unsafe. I assumed and thought Volvo's were great on miles and transmission so I didn't expect it to be having these type of issues. I am a first time Volvo purchaser and highly disappointed and it's to expensive for all the hassles. All of the minor issues were expected because of the vehicle being a used car. Also, I cannot even check the transmission fluid levels in order to see if all I need is some transmission fluid, the dipstick that leads to the transmission is stuck, as in I have tried pulling, twisting and turning but to no avail. After purchasing a 300 dollar key pad from the dealer I expect more from the manual and at least to be able to check all fluids on the vehicle. If these minor issues didn't evolve into major issues with my Volvo vehicle I would not have an issue. Yet the problem is that these minor issues are indeed causing major repairs which is simply unacceptable and causing unsafe driving hazardous situations that could indeed affect the life of myself and other drivers. Thank you very much for listen and hopefully directly addressing my concerns.
