just purchased a used 4runner with 37k miles. I've read about the transmission shudder issue. My question is this...Even though I have not notice the shudder from my tranny, is it feasible to take it to the dealer and have them replace it under the TSB? I know I have a little while before my warranty expires, but if this is a known problem and the fix is to replace the entire tranny, I'm afraid to wait, and as soon as my warranty expires, the tranny will start shuddering and then I'm SOL. I'm a little gun shy right now because my tranny crapped out on my Saturn Outlook (which has a crappy tranny), which is the reason I'm in a 4Runner. Traded that Saturn for my 4runner. Now I find out about the tranny problems on these 4runners.
