Default Transmission problems

Last night, I took a two hr drive on the interstate with cruise set at 80mph. When I got off the i-state, the tranny started acting up. Stopped at a stop light, then when I started going (normal driving, no heavy acceleration), the tranny didn't shift into 2nd until 3000rpm, then it shifted very hard. Same thing shifting into 3rd, 2800-3000rpm, shifted very hard. Stopped at next light, then when I started going, the tranny started out in either 2nd or 3rd, it didn't shift back down to 1st when I stopped. I pulled over and checked the fluid, it was a little low, and I had some tranny fluid with me, so I added fluid and started again. When I shifted into park, it had gone down to 1st, but if I stopped and didn't shift into park or reverse, it wouldn't shift down to 1st.

I have never had any tranny problems before, and as I mentioned, it just started when I got off the interstate.

Any ideas?

Thanks
Seth

Sounds like your appointment to the trans shop has been made. It definitely hints the sound of a rebuild. Sorry to hear of the bad news.

:cheers:

Vette mech-

Could you elaborate a little on things that I could check.

I changed my fluid and filter about 12-15k miles ago, should I change it again?

I read somewhere that there could be some trach in a TV valve that is causing the high rev and hard shift. Does this sound correct?

I haven't had any transmission problems before this. It has always shifted quick and on time, no prior signs of slipping.

Thanks for the help!!!

Seth

How many miles on this transmission? Does the fluid smell burnt? How does it act when the fluid is cold? How are the shifts if you manualy shift it. I don't trust tranny shops so maybe you have a good a mechanic, but my quess is that any shop you take it to is going to recommend a rebuild.
