Gearbox Tale of Whoa
I recently sold my high milage '99 K12LTC to a friend and purchased a low milage '03 for myself. We were both on a ride a couple of weekends ago when he tried to downshift and got stuck in 4th gear. We pulled over and checked out linkage, but it seemed to be a problem inside the gearbox.
So, Sunday we pulled the gearbox out of the '99 and when we opened the drain plug we got pieces of mettle and the foulest smelling oil.
Today, my friend took the gearbox over to one of our 3 Houston dealerships and the service manager told him to forget it and purchase a new gearbox to the tune of $3K.
Well... even with all the mettle that came out of that tranny, he rode ~75 miles home on it the day it broke and there were no grinding sounds. So I'm thinking that there is still a chance that the problem is with the syncros and the shifting mechanism and not the main gears.
What do you super users think of this failure? Have we heard of this type of failure before? Should we expect the dealer's service department to at least make an effort to see what is wrong before suggesting spending that kind of money on a '99 with 97K miles?
Also, if we really should not be trying to rebuild this gearbox, where would we start looking for a used replacement?
Thanks for your advice and opinions.
