My car's transmission degraded very quickly. Saturday I drove it one hundred miles city and highway, and noticed slight clunk accelerating from a stop. Sunday it had a lag before shifting into reverse and drive.
Monday morning, (cold), it would not shift into any gear.
I know that these cars have valve body issues after 100K, but the valve body was replaced 22K miles ago.
I cant believe that the tranny is shot since it was running like a top two days ago.
Electric/hydraulic issue?

Thank you

Have you scanned it for codes yet? Sounds like you could have lost pressure from the pump.

I took too transmission shop and they say transmission needs to be rebuilt. I do not know what codes they read.
Would pump fail without a sound?
I would like to try a fluid flush before a transmission rebuild.

A flush is not going to do much if it is not moving in any gear. Can you hear the actuators buzzing when you put it in drive?

I did not hear any buzzing when I tried all the gears. I did hear engine speed up when put car in gear.

Have you checked for blown fuses? You should hear something when you shift into drive?
