I tore a hole in the rubber seal that holds the b2 piston bushing in place. I put the car back together, and drove it, and it ran fine, but... IS there any problems that will occure becuause of this??? I really need to know. If there is, I will redo the job. Thank you

The seal is critical to the release of the B2 band, with a leak the band will not fully release and drag. The release oil is also used for the 3- 4 shift.

I was driving the car yesterday, and I had to come to a sudden stop, when I went to go again, I had no foward gears at all. There were no noises that I heard, it just wouldn't go. I checked the b2 piston, its still all in tact. Does this sound like something that could occur frorm the seal having a hole?

Absolutely, the seal is leaking. While the piston is out, also check the T seal on it for any damage.
