get it flushed, how many kms has it done? I have owned several auto terranos and the gearbox seems to be a temperamental thing on them, a good flush and new oil does them wonders. Local nissan dealer flushed mine for me, its not a job you can do yourself as they use a special machine and cycle fluid through the gearbox for a good hour or so then drain it all out before putting new oil in.
yea usually it is the that the valve body is just gunked up with heaps of crap thick old oil I was amazed at the amount of shit that came out of a couple of my ones haha
thanks for the advice i went to an auto trans shop this morning and explaned my symtom, he sugesssted that it could be the temp sensor in the trans that could be faulty.
so as kind as he was he gave me a resistor and showed me how to add it into the curcuit.
he did not seem to think it was the kick out, as earlry suggested by a mate of mine.
