I am having trouble with my A340H transmission. For a couple of weeks it shuddered from a standstill, and then would even out and be fine until I have to start moving again (1st gear is the problem). It has now started to slip, and the shudder is gone. I tried to change the fluid and filter, but it has the same result.

Okay now to the question: Does it need to be rebuilt? I have been doing some reading, and it seems the solenoids or valve body could cause this. Any thoughts? Anyone try changing these parts? I don't want to spend the money on parts if there isn't a reasonable chance of it working.

Any help would be greatly appreciated.
