1999 toyota Sienns Transmission Failure
 Overal we have bee happy with the XLE. 
With regular maintenance, it has given 
us much fewer problems than our 
previous Plymouth Voyager. However at 
72,000 miles the transmission is going 
faulty. I have heard from a Canadian 
toyota dealer that the transmission has 
been an issue with the Sienna. One 
owner said that their dealer routinely 
changes the transmission fluid at 
30,000 mile intervals. Toyota 
recommends 45,000. However, after 
searches on the internet it seems that 
engine failure due to oil sludge has 
been more of a common problem than the 
transmission. Personally, I don't think 
thats right for a $30,000. car that has 
been regularly maintained.
