I have a v6 firebird 1999 4l60e, got code p1870 for god knows how long (car dealer cleared check engine light before I bought it). Anyway it slips, has shuttle shifts, grinds between gears sometimes.I already know the transmission is dead, but don‘t know if a used transmission gets rusty (gears, solenoids, etc) overtime?Because there‘s a a rating transmission 12,000 miles but 1999Scared of rusty gears, clutches then its a wasteDoes rust happen in old transmissions with fluid or no?
Eventually, anything that had oil or fluid coating it disipates then moisture settles in. Once moistures settles, things rust. Moisture is in everything, I suggest if you like wasting your time changing transmissions for the heck of it, then sure. go ahead use it
GM did no longer change to the obd 2 computing gadget device until ninety six in there vehicles and suv's.So a 4l60e from ninety 3-ninety 5 might artwork from a 4x4 truck,Tahoe,suburban.92 and older does no longer artwork nor might a ninety six and extra moderen . stable success
if the transmission has sat outside then can rust if water does get into it. most yards keep transmissions inside. water can ruin a transmission. pull pan off transmission before installing if o.k then replace filter. if anything looks bad as in water in it or to much debris in the pan return it and get another one
