Hey guys just blew the tranny in my 1989 chevy 4x4. And of course I'm
broke so any help locating a good deal on one local to Buffalo,NY
would be greatly appreciated. It would be great if it was recently
rebuilt or known excellent condition as the last one from the scrap
yard only lasted a year.

When you shop for a used 700R4 from a bone yard pay attention to the
vehicle it came out of (mileage, tire size and axle ratio) because
that will give you a gauge as to how much service life it has left.
The 700R4's weakness is heat and certain senerios place a lot of heat
stress on it because it is otherwise a sound design. (the newer 4L60E
is basically a electronically controlled 700R4) You want a 87 or later
model or a earlier one that has been rebuilt and brought up to current
specs. Do instal a aux tranny cooler with next tranny and change fluid
and filter every 20 to 30 K with a fresh change when you install it.
Do this and you will have a long service life. Do stay away from shift
kits because the intermediate sprags are not that strong and while
they hold up fine with stock shifts they are prone to fail over time
with hard shift kits. (the factory softens the shifts for a reason)
