I have a 1996 Buick Regal. Until recently, it'* ran fan. And then, this past Sunday (as of the time of this post), the RPMs began to shoot up to 5 and 6 and the car lost acceleration. I thought it needed more transmission fluid, but today I found out that I had put too much in it. So my dad and I drained the pan and refilled it, but the car refused to go into gear. Let me rephrase -- it would go into gear, but it wouldn't go anywhere. I found several posts on various sites about how it might be a transmission pump or a transmission lockup solenoid, but the results upon testing them were still the same -- no acceleration at all. Does anyone know how this can be fixed without the need for a mechanic?

Got one of these?

Tech II'* point is you need a mechanic.
