300TE Transmission B-2 Band
OK. First let me state I must be the dumbest person on earth. Let me tell you what I did. I was changing the B-2 Piston o-ring right under the cover. (i believe it is the B-2, the second large round cover passenger side). Once the cover was off I pulled out the item with the spring on it. I assume that is the piston itself. Well as soon as i did that I realized that it was probably connected to something inside the transmission and I just screwed myself. Sure enough. I put it all back togethor and now I have no forward gears. So I am assuming the piston is no longer connected to the band. Is that correct. How can I connect it? I have sean some people say you can change the B-2 piston from the outside so I am assuming there is a way to reconnect it. Any advice is appreciated.

Well, you are lucky. There is a pin that connects the band to the piston. Just take back out the piston and look in. You should see a pin that needs to be centered in the piston. If it is not there, just take off the pan and it should be there.
Good luck

Benzmac,
Thanks for the tip. I would believe it is in the pan because when I pulled out the piston I heard something fall. Here is my question. After I recover the pin where do I stick it. In the end of the piston and slide that in or in the band and then slide the piston on to that. The hole isn't very big in the transmission for the piston. Not much room to get my fingers in there. Can it be accessed from underneath when the pan is off? I don't have much room as when I undo my tranmission mount the tranny doesn't come down very far. Must be my new motor mounts. Chuck |

I dont think that you will have access from the pan area. As I recall, there is a large aluminum gasket plate that blocks access. I cant be sure but that is what my memory is telling me. If it is at all possible, you will need some forcepts or long hemostats to hold the pin in place while replacing the piston.

The pin is made to the piston, but it is limp. To reach it from the inside you will have to drop the valve body.
Remove the piston and use some firm grease to give it lift and reinsert.

Well as always this forum saved me. I got the pin back in and now I have forward gears again. Thanks to all who replied.
