no. 4 solenoid, a340h

New to the 4runner world, I was wondering if anyone knows how long a transmission will hold up if you get a "code 65". I understand this to be the no.4 solenoid which i am told is in the connected transfer case. If it is toast, does 2550 sound remotely reasonable for fixing the transmission (im assuming rebuild :disappoin ). Thanks in advance for any input. :smile:

(8-19-05) To clarify a bit, I am wondering if I avoid using the overdrive on my 4runner, will that prolong the use of this tranny before needing to rebuild?
